The report was rejected by the Indian National Congress and the All-India Muslim League. The report led to the Civil Disobedience Movement in India.

The Simon Commission was a controversial commission. The Indian National Congress boycotted the commission because it did not have any Indian members. The All-India Muslim League also boycotted the commission because it did not give any representation to the Muslims. The Simon Commission was a major turning point in the history of India. It led to the Civil Disobedience Movement and the Round Table Conferences.

The correct answer is D. Manna asked Rohan if he has ever sat in a trolley bus.

The sentence "Have you sat in a trolley bus before?" is a present perfect interrogative sentence. It asks about an event that has happened or may have happened in the past. The present perfect tense is used to talk about events that have happened or may have happened at any time up to the present moment. The past participle "sat" is used to form the present perfect tense.

The word "ever" is used to ask about a general experience or event. In this case, Manna is asking Rohan if he has ever sat in a trolley bus, regardless of when it happened.

The other options are incorrect because they do not use the present perfect tense. Option A uses the past tense "had sat", which is used to talk about events that happened at a specific time in the past. Option B uses the past perfect tense "had sat before", which is used to talk about events that happened before another event in the past. Option C uses the simple past tense "sat", which is used to talk about events that happened at a specific time in the past.

The correct answer is C. Security Council.

The Security Council is one of the six principal organs of the United Nations and is responsible for maintaining international peace and security. It has 15 members, five of which are permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 non-permanent members elected by the General Assembly for two-year terms.

The Security Council has the primary responsibility for the maintenance of international peace and security. It can adopt resolutions that are binding on all member states. The Security Council also has the power to establish peacekeeping operations, to impose sanctions, and to authorize the use of force.

The Security Council is often referred to as the "most powerful" organ of the United Nations because of its ability to adopt binding resolutions. However, the Security Council is also the most controversial organ of the United Nations because of the veto power that each of the five permanent members has. This means that any one of the permanent members can veto a resolution, even if it is supported by the other 14 members of the Council.

The Security Council has been criticized for its inability to take action in some of the most serious crises of recent years, such as the Rwandan genocide and the Syrian civil war. However, the Security Council has also played a key role in resolving some of the most intractable conflicts of the 20th century, such as the Cold War and the decolonization of Africa.

The Security Council is an essential part of the United Nations system and plays a vital role in maintaining international peace and security. However, the Security Council is also a flawed institution that is in need of reform.

The correct answer is: A) Tropical monsoon.

West Bengal primarily experiences a tropical monsoon climate. This type of climate is characterized by hot, humid summers and warm, dry winters. The monsoon rains are caused by the seasonal shift of the Intertropical Convergence Zone (ITCZ). The ITCZ is a band of low pressure that lies near the equator. During the summer, the ITCZ shifts northward, bringing with it warm, moist air from the Indian Ocean. This air rises and cools, causing the formation of clouds and rain. The monsoon rains are essential for agriculture in West Bengal.

The other options are incorrect because they do not describe the climate of West Bengal accurately.

Arid climates are characterized by low rainfall and high temperatures. Arid climates are found in deserts and semi-deserts.

Mediterranean climates are characterized by warm, dry summers and cool, wet winters. Mediterranean climates are found in the Mediterranean region, California, and parts of Australia.

Temperate climates are characterized by moderate temperatures and rainfall. Temperate climates are found in most of Europe, North America, and Asia.

The correct answer is: A) Confiscate Zamindari estates without direct heirs.

The Zamindari system was a system of land tenure in India under which a landlord, known as a zamindar, held a large estate from the government and collected revenue from the peasants who worked the land. The Sunset Law of 1859 was passed by the British government in an attempt to reform the Zamindari system. The law stated that all zamindari estates would be confiscated if the zamindar died without a direct heir. This was intended to break up the large zamindari estates and redistribute the land to smaller farmers.

Option B is incorrect because the Sunset Law of 1859 did not aim to increase land revenue. In fact, the law was intended to reduce the amount of revenue that the zamindars collected from the peasants.

Option C is incorrect because the Sunset Law of 1859 did not aim to promote agricultural reforms. The law was not concerned with improving the way that land was farmed.

Option D is incorrect because the Sunset Law of 1859 did not aim to abolish slavery. Slavery was abolished in India in 1843, 16 years before the Sunset Law of 1859 was passed.

The correct answer is D. established on insecure foundations.

The phrase "built upon sand" is a metaphor for something that is not secure or reliable. In this case, the speaker is saying that the man's plans are not based on solid ground, and are therefore likely to fail.

Option A, based on inexperience, is incorrect because it does not address the issue of the man's plans being insecure. The man may be inexperienced, but that does not necessarily mean that his plans are not sound.

Option B, resting on immature ideas, is incorrect for the same reason. The man's ideas may be immature, but that does not necessarily mean that his plans are not feasible.

Option C, resting on cheap material, is incorrect because it does not address the issue of the man's plans being insecure. The man may be using cheap materials, but that does not necessarily mean that his plans are not going to work.

Therefore, the correct answer is D. established on insecure foundations.

The rules and regulations of the Municipal Administration of the state are described in the West Bengal Municipal Act, 1993.

The correct answer is D) All of the above.

Many workers from West Bengal migrate to other states like Kerala, Maharashtra, and Gujarat for employment in industrial sectors, agriculture, and information technology.

According to the 2011 census, West Bengal is the third most populous state in India, with a population of over 91 million people. The state has a long history of migration, with people moving from rural areas to urban areas in search of better opportunities. In recent years, there has also been a significant increase in the number of people migrating from West Bengal to other states.

There are a number of reasons why people from West Bengal migrate to other states. One reason is that there are more job opportunities in other states. The industrial sectors in Kerala, Maharashtra, and Gujarat are particularly attractive to migrants from West Bengal. Another reason for migration is that the cost of living is lower in other states. This is especially true for states like Kerala, which have a lower cost of living than West Bengal.

The migration of people from West Bengal to other states has a number of implications. One implication is that it can lead to a brain drain in West Bengal. This is because many of the people who migrate are highly skilled and educated. Another implication is that it can lead to a shortage of labor in West Bengal. This is because many of the people who migrate are young and able-bodied.

The government of West Bengal has taken a number of steps to address the issue of migration. One step is to provide more job opportunities in the state. Another step is to improve the infrastructure in the state. The government has also tried to improve the quality of education in the state.

Despite the efforts of the government, the issue of migration remains a challenge for West Bengal. The government will need to continue to take steps to address this issue in order to improve the lives of the people of West Bengal.

The correct answer is A. He said that he must go next week.

The other options are incorrect because they do not accurately reflect the meaning of the original sentence.

Option B, "He said that he must go the following week," is incorrect because it changes the order of the words in the original sentence. The original sentence says "I must go next week," but Option B says "He said that he must go the following week." This changes the meaning of the sentence because it implies that the speaker is talking about someone else who must go next week, rather than himself.

Option C, "He said that he would have to go the following week," is incorrect because it changes the tense of the verb. The original sentence uses the present tense, but Option C uses the future tense. This changes the meaning of the sentence because it implies that the speaker is talking about something that will happen in the future, rather than something that is happening now.

Option D, "He said that he was to go the following week," is incorrect because it changes the mood of the sentence. The original sentence is in the indicative mood, but Option D is in the subjunctive mood. This changes the meaning of the sentence because it implies that the speaker is talking about something that is possible or probable, rather than something that is certain.

The correct answer is (c), Goffman.

Role distance is a concept in sociology that refers to the ways in which individuals distance themselves from the roles they are expected to play in society. Goffman argued that individuals are constantly playing a variety of roles, and that they often feel a sense of tension or conflict between these roles. This tension can lead to role distance, which is a way of managing these conflicting expectations.

There are a number of ways in which individuals can express role distance. One way is to simply ignore the expectations associated with a particular role. For example, a student might ignore the expectation that they should always be respectful of their teachers. Another way to express role distance is to make fun of or ridicule the role. For example, a person might make jokes about the expectations associated with being a parent. Finally, individuals can also express role distance by simply refusing to play the role at all. For example, a person might refuse to take on a leadership position at work.

Goffman argued that role distance is a necessary part of social life. He believed that it allows individuals to manage the conflicting expectations that they face on a daily basis. Without role distance, individuals would be constantly feeling stressed and overwhelmed.

Goode, Newcomb, and Hiller are all sociologists who have made significant contributions to the field. However, they did not develop the concept of role distance.

Optical fiber is the fastest communication channel because it uses light to transmit data. Light travels at the speed of light, which is about 300,000 kilometers per second. Microwaves, radio waves, and other types of electromagnetic radiation also travel at the speed of light, but they are not as efficient at carrying data as optical fiber.

Microwaves are a type of electromagnetic radiation with a wavelength of about 1 millimeter to 1 meter. They are used for a variety of purposes, including communication, radar, and cooking. Microwaves are not as efficient at carrying data as optical fiber because they are more easily absorbed by materials.

Radio waves are a type of electromagnetic radiation with a wavelength of about 1 millimeter to 100 kilometers. They are used for a variety of purposes, including communication, broadcasting, and navigation. Radio waves are not as efficient at carrying data as optical fiber because they are more easily absorbed by materials and can be interfered with by other sources of radio waves.

All of these types of electromagnetic radiation travel at the speed of light, but optical fiber is the fastest communication channel because it is the most efficient at carrying data.

The correct answer is A. Oxygen.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in molecules of the sugar, glucose.

The process of photosynthesis can be summarized by the following chemical equation:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

In this equation, six molecules of carbon dioxide (CO2) and six molecules of water (H2O) are combined with light energy to produce one molecule of glucose (C6H12O6) and six molecules of oxygen (O2).

The oxygen gas that is released during photosynthesis is a byproduct of the reaction. It is not used by the plant, but is released into the atmosphere.

The other options are incorrect because they are not produced during photosynthesis. Nitrogen (N2) is the most abundant gas in the atmosphere, and it is not used by plants. Water vapor (H2O) is a product of transpiration, which is the process by which plants lose water vapor through their leaves. Carbon dioxide (CO2) is a reactant in photosynthesis, and it is not released during the process.

The correct answer is: B. Variable

In the short run, the quantity of at least one factor of production is fixed. This means that the factor ratio, which is the ratio of the quantities of the variable factors to the quantity of the fixed factor, can change. For example, if a firm has a fixed amount of capital, it can increase the amount of labor it uses to produce more output. In this case, the factor ratio would increase.

Option A is incorrect because the factor ratio can change in the short run. Option C is incorrect because the factor ratio is not always constant. Option D is incorrect because the factor ratio can change in the short run.

The correct answer is from.

The word "from" is used to indicate the cause of death. In this case, the person died from overwork. This means that the person's death was caused by working too much.

Here are some examples of how the other options could be used in a sentence:

• The person died of a heart attack.
• The person died with their family by their side.
• The person died to save their loved ones.

The correct answer is (c) 27.

A two-digit number is a number between 10 and 99. The first digit can be any number from 1 to 9, and the second digit can be any number from 0 to 9. This means that there are 10 possible first digits and 10 possible second digits, for a total of $10 times 10 = 100$ two-digit numbers.

To find the number of two-digit numbers that are divisible by 3, we can use the following formula:

Number of multiples of $n$ from 1 to $m$ = $frac{m}{n} + leftlfloor frac{m}{n} rightrfloor$

where $m$ is the upper limit and $n$ is the divisor.

In this case, $m = 99$ and $n = 3$. Substituting these values into the formula, we get:

Number of multiples of 3 from 1 to 99 = $frac{99}{3} + leftlfloor frac{99}{3} rightrfloor = 33 + 33 = 66$

However, we need to subtract 1 from this number because the number 0 is divisible by 3, but it is not a two-digit number. Therefore, the number of two-digit numbers that are divisible by 3 is $66 - 1 = boxed{27}$.

Option (a), 30, is incorrect because it is the total number of two-digit numbers. Option (b), 29, is incorrect because it is the number of two-digit numbers that are not divisible by 3. Option (d), 26, is incorrect because it is the number of two-digit numbers that are odd.

The correct answer is: C. September 23

The Saka calendar is a solar calendar used in India and Nepal. It is a lunisolar calendar, which means that it is based on the cycles of the moon and the sun. The Saka calendar is 78 years ahead of the Gregorian calendar. This means that the first day of the Saka year is always 78 days after the first day of the Gregorian year.

The month of Bhadra is the sixth month of the Saka calendar. It begins on the day of the new moon that falls between August 23 and September 22 in the Gregorian calendar. The end of the month of Bhadra is marked by the full moon that falls between September 22 and October 21 in the Gregorian calendar.

Therefore, the corresponding Gregorian date of the Saka month, Bhadra is September 23.

Here is a brief explanation of each option:

• A. July 23 is incorrect because the month of Bhadra does not begin on July 23 in the Gregorian calendar.
• B. August 23 is incorrect because the month of Bhadra does not begin on August 23 in the Gregorian calendar.
• C. September 23 is correct because the month of Bhadra begins on September 23 in the Gregorian calendar.
• D. October 23 is incorrect because the month of Bhadra does not end on October 23 in the Gregorian calendar.

The correct answer is: D. All of the above

A Lorenz curve is a graphical representation of the distribution of income or wealth. It shows the cumulative percentage of income or wealth that is received by the bottom x% of households, where x goes from 0 to 100. The Lorenz curve for a perfectly equal distribution would be a straight line from the bottom left corner to the top right corner, since everyone would receive the same amount of income or wealth. The more curved the Lorenz curve, the more unequal the distribution of income or wealth.

The Gini coefficient is a measure of the inequality of income distribution. It is calculated by taking the area between the Lorenz curve and the line of perfect equality, and dividing it by the total area under the line of perfect equality. The Gini coefficient ranges from 0 to 1, with 0 representing perfect equality and 1 representing perfect inequality.

The proportion of income received by different size groups is another way to measure income inequality. This measure is calculated by dividing the total income received by each group by the total population. The higher the proportion of income received by a small group of people, the more unequal the distribution of income.

All of these measures can be used to compare income inequality across countries or over time. They can also be used to track changes in income inequality within a country.

The correct answer is B. Only I and II are implicit.

The statement "Quality of life of a person is not dependent only on his wealth" does not imply that the aim of most people is just to acquire more wealth. It also does not imply that wealth does not contribute to the quality of life at all. It simply means that there are other factors that contribute to the quality of life besides wealth.

Assumption I is implicit in the statement because the statement is saying that there are other factors that contribute to the quality of life besides wealth. Assumption II is also implicit in the statement because the statement is not saying that wealth does not contribute to the quality of life at all. Assumption III is not implicit in the statement because the statement is not saying that wealth does not contribute to the quality of life at all.

Here are some examples of factors that contribute to the quality of life besides wealth:

• Health
• Relationships
• Happiness
• Freedom
• Security
• Meaning and purpose in life

The correct answer is C. Representative democracy.

In a representative democracy, citizens elect representatives to make decisions on their behalf. These representatives are accountable to the citizens and can be voted out of office if they do not perform well.

India is a representative democracy. The citizens of India elect members of Parliament to represent them in the central government. They also elect members of the legislative assemblies to represent them in the state governments. The members of Parliament and the legislative assemblies are accountable to the citizens and can be voted out of office if they do not perform well.

A direct democracy is a form of government in which the citizens of a country directly participate in the decision-making process. This can be done through public meetings, referendums, or initiatives.

A presidential democracy is a form of government in which the head of state is elected by the people. The president is usually the head of government as well, but in some cases, the head of government is a prime minister who is appointed by the president.

A dictatorship is a form of government in which one person or a small group of people holds all the power. There is no freedom of speech or assembly, and the people have no say in how they are governed.

In conclusion, India is a representative democracy. The citizens of India elect members of Parliament and the legislative assemblies to represent them in the central and state governments. These representatives are accountable to the citizens and can be voted out of office if they do not perform well.

The correct answer is C. Pascal's law.

Pascal's law states that pressure applied to an enclosed fluid is transmitted equally in all directions. This principle is used in hydraulic brakes to amplify the force applied by the driver's foot. When the driver presses the brake pedal, it pushes a piston in the master cylinder. This piston pushes fluid through a tube to a smaller piston in the brake caliper. The smaller piston is connected to the brake pads, which press against the brake rotors to slow the car.

Bernoulli's law states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. This law is used in some types of air brakes, but it is not used in hydraulic brakes.

Poseuille's law states that the flow rate of a fluid through a pipe is proportional to the pressure difference across the pipe, the fourth power of the radius of the pipe, and the viscosity of the fluid. This law is not directly related to the working of hydraulic brakes.

Archimedes' principle states that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object. This principle is not directly related to the working of hydraulic brakes.

The correct answer is (a). Contingent interest.

A contingent interest is an interest in property that is not certain to vest. In this case, C's interest in the property is contingent on him attaining the age of majority. If C does not attain the age of majority, his interest in the property will lapse and the property will revert to A.

A vested interest is an interest in property that is certain to vest. In this case, A has a vested interest in the property because he is the current owner of the property.

Both contingent and vested interest is not the correct answer because C does not have a vested interest in the property.

No interest is not the correct answer because C does have an interest in the property, even though it is a contingent interest.

The correct answer is: D. gas-fired power project.

An atomic power project is a power plant that uses nuclear fission to generate electricity. A hydro-electric project is a power plant that uses the power of moving water to generate electricity. A thermal power project is a power plant that uses heat to generate electricity. A gas-fired power project is a power plant that uses natural gas to generate electricity.

Gas-fired power plants are the most common type of power plant in the United States. They are relatively inexpensive to build and operate, and they can be started and stopped quickly, which makes them well-suited for meeting peak demand. However, gas-fired power plants also emit greenhouse gases, which contribute to climate change.

Atomic power projects are less common than gas-fired power plants, but they are becoming more popular as the cost of nuclear power decreases. Nuclear power plants are very efficient at generating electricity, and they do not emit greenhouse gases. However, nuclear power plants are also very expensive to build and operate, and they produce radioactive waste that must be carefully disposed of.

Hydro-electric projects are the least common type of power plant in the United States. They are only feasible in certain locations where there is a large body of water with a significant drop in elevation. Hydro-electric projects are very efficient at generating electricity, and they do not emit greenhouse gases. However, they can have a negative impact on the environment, as they can disrupt the flow of water and damage fish habitats.

Thermal power projects are the oldest type of power plant. They are still widely used, but they are becoming less common as other types of power plants become more efficient. Thermal power plants emit greenhouse gases, which contribute to climate change.

The correct answer is: A. a-1, b-2, c-3

Prof. Robin is a professor of finance at the University of Chicago. He is known for his work on security profit. Prof. Milton Kafoglis is a professor of finance at the University of Pennsylvania. He is known for his work on Marris growth maximisation. Prof. Rothschild is a professor of finance at the University of California, Berkeley. He is known for his work on output maximisation.

Security profit is the difference between the market value of a security and its book value. Marris growth maximisation is a theory of corporate finance that argues that firms should maximise their growth rate subject to a constraint on their profitability. Output maximisation is a theory of corporate finance that argues that firms should maximise their output subject to a constraint on their costs.

In the question, List-I contains the names of three professors of finance, and List-II contains three theories of corporate finance. The correct answer is the one that matches each professor with the theory that they are best known for.

Option A matches Prof. Robin with security profit, Prof. Kafoglis with Marris growth maximisation, and Prof. Rothschild with output maximisation. This is the correct answer because it is the only option that matches each professor with the theory that they are best known for.

Option B matches Prof. Robin with Marris growth maximisation, Prof. Kafoglis with output maximisation, and Prof. Rothschild with security profit. This is not the correct answer because it does not match Prof. Robin with the theory that he is best known for, which is security profit.

Option C matches Prof. Robin with output maximisation, Prof. Kafoglis with security profit, and Prof. Rothschild with Marris growth maximisation. This is not the correct answer because it does not match Prof. Kafoglis with the theory that he is best known for, which is Marris growth maximisation.

The answer is D. 104 : 78.

In each of the other options, the first number is twice the second number. For example, 80 is twice 60, 96 is twice 80, and 64 is twice 48. However, 104 is not twice 78.

The correct answer is: C. the income of the consumer does not change.

The ceteris paribus clause in the law of demand states that all other factors that might affect demand remain constant while the price of the good changes. This means that the income of the consumer is not included in the ceteris paribus clause.

If the income of the consumer changes, it will affect the demand for the good. For example, if the income of the consumer increases, they will be able to afford to buy more goods, including the good in question. This will increase the demand for the good. Conversely, if the income of the consumer decreases, they will be able to afford to buy fewer goods, including the good in question. This will decrease the demand for the good.

Therefore, the ceteris paribus clause in the law of demand does not mean that the income of the consumer does not change.

The word "amature" is a misspelling of the word "amateur." It is often used to describe someone who is not very good at something, but this is not the correct meaning of the word.

The words "designation," "controversy," and "burglar" are all spelled correctly.

The correct answer is: B. Thermal

Thermal power plants are the most common type of power plant in India, accounting for over 60% of the country's electricity generation. They use coal, oil, or natural gas to heat water, which turns into steam that drives a turbine to generate electricity.

Thermal power plants have shown the largest growth till the Eighth plan because they are relatively inexpensive to build and operate. They are also reliable sources of electricity, which is important for a country like India that is experiencing rapid economic growth.

However, thermal power plants also have a number of disadvantages. They are a major source of air pollution, and they contribute to climate change. They also require large amounts of water, which can be a problem in areas that are already facing water shortages.

In recent years, there has been a growing focus on developing renewable sources of energy, such as solar and wind power. These sources of energy are cleaner and do not produce greenhouse gases. However, they are also more expensive to build and operate than thermal power plants.

It is likely that India will continue to rely on thermal power plants for the foreseeable future. However, the government is also working to increase the share of renewable energy in the country's energy mix.

Here is a brief explanation of each option:

• Hydro power plants use the power of moving water to generate electricity. They are a clean and renewable source of energy, but they can be expensive to build and operate.
• Gas power plants use natural gas to generate electricity. They are a cleaner and more efficient source of energy than coal-fired power plants, but they still produce greenhouse gases.
• Nuclear power plants use the heat from nuclear fission to generate electricity. They are a clean and efficient source of energy, but they produce radioactive waste that must be carefully disposed of.

The correct answer is:

D. no article

The reason is that the food is not specific. It could be any food. If we used an article, it would imply that we were talking about a specific food. For example, if we said "The food that you cooked was very good!", it would imply that we were talking about a specific dish that you had cooked. However, since we are not talking about a specific dish, we do not need an article.

Here are some more examples of how to use articles with food:

• I like to eat pizza. (No article is needed because pizza is a general food item.)
• I like to eat the pizza that you made. (An article is needed because we are talking about a specific pizza.)
• I like to eat Italian food. (No article is needed because Italian food is a general type of food.)
• I like to eat the Italian food that you made. (An article is needed because we are talking about a specific Italian dish.)

I hope this helps!

The correct answer is D. All of the above.

The demand for a good or service is the amount of that good or service that consumers are willing and able to purchase at various prices during a given period of time. The demand for a good or service can change for a variety of reasons, including changes in consumer income, changes in population, changes in fashion and customs, and changes in the prices of related goods and services.

• Change in consumer income: When consumers have more money to spend, they are typically willing and able to purchase more goods and services. This is known as the income effect. The income effect can cause the demand for a good or service to increase or decrease, depending on whether the good or service is a normal good or an inferior good. A normal good is a good whose demand increases when consumer income increases. An inferior good is a good whose demand decreases when consumer income increases.
• Change in population: When the population increases, there are more consumers in the market. This can lead to an increase in the demand for goods and services.
• Change in fashion and customs: Fashion and customs can change over time, which can lead to changes in the demand for goods and services. For example, if a certain type of clothing becomes popular, the demand for that clothing will increase.
• Change in the prices of related goods and services: The demand for a good or service can also be affected by the prices of related goods and services. For example, if the price of a substitute good decreases, the demand for the good will decrease. A substitute good is a good that can be used in place of another good. For example, coffee and tea are substitute goods. If the price of coffee decreases, the demand for tea will decrease.

In conclusion, the demand for a good or service can change for a variety of reasons. The most common reasons for changes in demand are changes in consumer income, changes in population, changes in fashion and customs, and changes in the prices of related goods and services.

The correct answer is $boxed{rm{hat i} - 4{rm{hat j}}}$.

The vorticity vector is defined as the curl of the velocity vector, which is given by:

$$omega = nabla times overrightarrow V$$

In Cartesian coordinates, the curl can be written as:

$$omega = left( dfrac{partial Q}{partial x} - dfrac{partial P}{partial y} right) {rm{hat i}} + left( dfrac{partial P}{partial z} - dfrac{partial Q}{partial x} right) {rm{hat j}} + left( dfrac{partial R}{partial y} - dfrac{partial Q}{partial z} right) {rm{hat k}}$$

where $P$, $Q$, and $R$ are the $x$, $y$, and $z$ components of the velocity vector, respectively.

In this case, the velocity vector is given by:

$$overrightarrow V = 2xyhat i - {{rm{x}}^2}{rm{zhat j}}$$

Therefore, the components of the vorticity vector are:

$$begin{align}
dfrac{partial Q}{partial x} - dfrac{partial P}{partial y} &= 2y - 0 = 2y
dfrac{partial P}{partial z} - dfrac{partial Q}{partial x} &= -2xz = -2z
dfrac{partial R}{partial y} - dfrac{partial Q}{partial z} &= 0 - 0 = 0
end{align}$$

Therefore, the vorticity vector is given by:

$$omega = 2y{rm{hat i}} - 2z{rm{hat j}}$$

Evaluating the vorticity vector at the point $(1, 1, 1)$ gives:

$$omega = (2)(1){rm{hat i}} - (2)(1){rm{hat j}} = {rm{hat i}} - 2{rm{hat j}}$$

The correct answer is (a) Parsi.

Parsi people have the lowest fertility rate in India, with an average of 1.5 children per woman. This is significantly lower than the national average of 2.2 children per woman. There are a number of reasons for this, including the fact that Parsi families are typically small, and that many Parsi women choose to have careers rather than children.

Sikhs have a fertility rate of 2.1 children per woman, which is close to the national average. This is likely due to the fact that Sikhism is a religion that values family life. Jains have a fertility rate of 2.0 children per woman, which is also close to the national average. This is likely due to the fact that Jainism is a religion that values non-violence and compassion, which may lead to people choosing to have smaller families. Marwaris have a fertility rate of 2.5 children per woman, which is higher than the national average. This is likely due to the fact that Marwaris are a community that values tradition and family, and that many Marwari women choose to stay at home and raise children.

It is important to note that these are just averages, and there is a great deal of variation within each community. There are many Parsi families with more than two children, and many Sikh, Jain, and Marwari families with fewer than two children.

The missing number is 849.

The numbers in the sequence are the sum of the squares of the first $n$ natural numbers, where $n$ is the position of the number in the sequence. For example, the first number in the sequence is 1, which is the square of 1. The second number in the sequence is 4, which is the sum of the squares of 1 and 2. The third number in the sequence is 9, which is the sum of the squares of 1, 2, and 3.

The missing number is the 10th number in the sequence, which is the sum of the squares of 1, 2, 3, ..., 10. This sum is equal to $849$.

Here is a table of the first few numbers in the sequence:

Number | Sum of squares of first $n$ natural numbers
------- | --------
1 | 1
2 | 4
3 | 9
4 | 16
5 | 25
6 | 36
7 | 49
8 | 64
9 | 81
10 | 100

As you can see, the numbers in the sequence increase rapidly. This is because the square of a number is always greater than or equal to the number itself. For example, $1^2 = 1$, but $2^2 = 4$. This means that the sum of the squares of the first $n$ natural numbers is always greater than or equal to $n$.

The missing number in the sequence is 849. This is because the sum of the squares of the first 10 natural numbers is equal to 100 + 100 + 81 + 64 + 49 + 36 + 25 + 16 + 9 + 4 = 849.

The correct answer is B. Rectifier.

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). This is done by using a semiconductor device, such as a diode, to allow current to flow in only one direction.

A transformer is a device that transfers electrical energy from one circuit to another without changing the frequency of the power. This is done by using two coils of wire that are wrapped around a common core. The current in one coil creates a magnetic field, which induces a current in the other coil.

An induction coil is a type of transformer that is used to create a high voltage from a low voltage. This is done by using a coil of wire that is wrapped around a core of iron. When current flows through the coil, it creates a magnetic field that induces a current in the core. This current then flows through the secondary coil, which is connected to the load.

A dynamo is a device that converts mechanical energy into electrical energy. This is done by using a rotating coil of wire that is placed in a magnetic field. The rotation of the coil creates a current in the wire, which is then used to power a load.

In conclusion, the correct answer to the question "A device used for converting a.c. into d.c. is called" is B. Rectifier.

There are 12 pairs of ribs in the human body, which are connected to the spine at the back and to the sternum (breastbone) at the front. The first seven pairs of ribs are called true ribs because they are attached directly to the sternum. The next five pairs of ribs are called false ribs because they are not attached directly to the sternum. The last two pairs of ribs are called floating ribs because they are not attached to the sternum at all.

The ribs protect the organs in the chest, such as the heart and lungs. They also help with breathing by expanding and contracting the chest cavity.

The number of ribs can vary from person to person. Some people may have an extra rib, or they may be missing one. This is usually not a problem, but it can sometimes cause pain or other health problems.

The correct answer is: B. Negative

A Giffen good is a good that people demand more of as their income decreases. This is because the good is relatively cheaper for them when their income is low, and they are willing to sacrifice other goods to consume more of it.

For example, imagine that you are very poor and you only have enough money to buy rice and beans. If your income increases, you will be able to afford to buy other goods, such as meat and vegetables. However, you may still choose to buy more rice and beans, because they are relatively cheaper for you now.

The income effect towards a Giffen good is negative because the demand for the good decreases as income increases. This is because the good becomes relatively more expensive for the consumer as their income increases.

The other options are incorrect because:

• Option A is incorrect because the income effect towards a Giffen good is negative.
• Option C is incorrect because the income effect towards a Giffen good is not zero.
• Option D is incorrect because the income effect towards a Giffen good is not none of these.

The correct answer is (a) Cotton.

The Pink Revolution is a term used to describe the development of genetically modified cotton varieties that are resistant to the pink bollworm. The pink bollworm is a major pest of cotton, and the development of resistant varieties has had a significant impact on the cotton industry.

The pink bollworm is a moth that attacks cotton bolls, or the fruit of the cotton plant. The larvae of the pink bollworm feed on the cotton fibers, causing significant damage to the crop. The pink bollworm is a major pest of cotton in many parts of the world, including the United States, China, and India.

The development of genetically modified cotton varieties that are resistant to the pink bollworm has been a major breakthrough in the fight against this pest. These varieties have been engineered to produce a protein that is toxic to the pink bollworm. When the larvae of the pink bollworm feed on these varieties, they ingest the toxin and die.

The development of genetically modified cotton varieties that are resistant to the pink bollworm has had a significant impact on the cotton industry. These varieties have allowed farmers to reduce the use of pesticides, which has saved them money and reduced the environmental impact of cotton production. In addition, these varieties have increased yields, which has benefited farmers and consumers alike.

The Pink Revolution is a significant example of how biotechnology can be used to improve agriculture and protect the environment.

The correct answer is (d). The Champaran Satyagraha was not the first movement launched by M.K. Gandhi on an All India level. The first All India movement launched by M.K. Gandhi was the Non-Cooperation Movement of 1920-22.

The Champaran Satyagraha was a peasant uprising in the Champaran district of Bihar, India, led by Mahatma Gandhi in 1917. The movement was against the British indigo plantation system, which was exploitative and oppressive to the peasants. The peasants were forced to grow indigo on their land, even if they did not want to, and they were paid very little for their labor. The system was also very unfair, as the British planters were given a lot of power and the peasants had very little say in how their lives were run.

The Champaran Satyagraha was a major turning point in Gandhi's life and career. It was the first time that he had led a major movement on a national scale, and it was also the first time that he had used the strategy of satyagraha, or nonviolent resistance. The movement was successful in achieving its goals, and it helped to raise awareness of the plight of the peasants in India. It also helped to establish Gandhi as a national leader and a champion of the rights of the poor and oppressed.
