State the dependence of angle of deviation: (i) On the refractive index of the material of the prism. (ii) On the wavelength of tight.

Answer»

(i) If the refractive index of the material increases, the angle of deviation also increases. 

(ii) Lesser the wavelength of light, greater is the angle of deviation.

5454.

Does total internal reflection occur when light passes from a rarer medium to a denser medium ?

Answer»

No

Because when light goes from a denser medium to a rarer one, the refracted Ray moves away from the normal. Hence it's possible for there to exist a particular angle of incidence (critical angle) such that the refracted Ray makes an angle of 90 degrees.

In the other case, when the light goes from rarer to denser medium, light bends towards the normal, thus there wouldn't exist any angle of incidence for which the refracted Ray becomes 90 degrees with the normal.

What is meant by Ecosystem? Explain three adverse effects of mining on the ecosystem.

Answer»

Ecosystem: An Ecosystem is a complex set of relationship among the living resources habitats and residents of an area but changing global pattern of land use have had a significant negative effect on ecosystem.

There is a biotic balance in an ecosystem, which makes it possible to sustain the various interdependent members (plant and animal life). Ecosystem maintains a very delicate balance. Various human activities have been done to disrupt this balance and destroy the world’s ecosystems.

Adverse effect of mining on ecosystem:

1. It causes deforestation and removal of vegetation. In order to construct a mine large amount of land has to be cleared off trees and vegetation. This is bad for environment. 

2. The waste material remaining after the valuable minerals have been extracted is called tailing. These tailings are generally made up of hazardous material. Dust from these tailings causes air pollution. 

3. Chemical like arsenic and iron are very harmful. When it rains these chemicals find their way to ground water, surrounding water bodies and soil. This pollutes water bodies as well as affects agriculture.

What is meant by privatisation? Explain in brief three arguments against privatization of public sector units in India.

Answer»

Privatization: Privatization means the transfer of managerial control of any public sector units to any private entrepreneur or to any private corporate body is called privatization.

Arguments against Privatization in India are:

1. Social welfare aspect is neglected: Main motive of the private sector enterprises is to earn maximum profits. Thus, the social welfare aspect is being neglected. 

2. Growth of monopoly power: Privatization may lead to the growth of monopoly power in the industry and services sectors. The weak Indian companies may either be closed down or taken over by some big companies. Ultimately the monopoly power of multi-national companies will grow more and more which would not be in the interest of economic development. 

3. Misutilization of resources: The private sector in India has been wasting away valuable resources in the name of securing profits by opting for obsolete technology and producing shoddy products. It depends entirely on Government technologies or imported know-how.

‘Efficient labour force is an important economic ingredient’. In this context, define efficiency of labour.Explain three factors that determine the efficiency of labour.

Answer»

‘Efficiency of Labour’: The amount of work which a labourer can do within a given time. —Dr. Saxena

In other words, efficiency of labour refers to the quantity and quality of goods and services which can be produced during a given period under certain prevailing conditions. 

Three factors that determine the efficiency of labour:

1. General and Technical Education: The general education broadens the knowledge, develops the intellect and improves the skill of a person. The technical education provides knowledge to a worker concerning different systems of work of the productive units. All these make an educated person more efficient and better in skill, as compared to an uneducated and untrained person.

2. Experience: The practical experience of work is gained by the worker during the training period. After that, he becomes perfect by doing day-to-day work, regularly and repeatedly. Simultaneously his efficiency also goes on increasing. Thus, an experienced worker is usually more efficient than an inexperienced one.

3. Climatic Factors: Climatic differences also affect the efficiency of labour Working under extreme climatic conditions is always more difficult than working in the temperate zones.

4. Working Conditions: A healthy and conducive work environment increases the level of efficiency. The facilities enjoyed by the worker determine labour efficiency to a significant extent. Employer-employee relations are also an important part of the work-environment. An employer, therefore, can contribute to labour efficiency by building a cordial relationship with his workers. (any three)

Define Privatisation. Discuss two arguments each in favour and against privatisatio.

Answer»

Privatization: “Refers to the sale of all or parts of a government’s equity in state owned enterprises to the private sector.”

Privatization means the transfer of managerial control of any public sector units to any private entrepreneur or to any private corporate body is called privatization.

Arguments in favour of privatization:

1. Greater flexibility in making decisions: Sometimes PSUs suffer losses just due to inadequate autonomy in the ‘decision making power’ of the management. If the PSUs are privatised, then the production and investment decisions of the management would be free from any Government intervention, and they would be purely guided by profit motive.

2. Improvement in Managerial Efficiency: Privatization is a means of improvement in managerial efficiency because the private sector is almost free from political interference.

When many areas of industial production are opened up for the private sector enterprises, then their investment in the industrial sector is expected to increase to a large extent. Higher investment would mean creation of greater employment and income opportunities within the economy.

Arguments against privatisation: 

1. Social welfare aspect is neglected: The private sector enterprises operate mainly for the maximisation of profit. Hence this measure does not guarantee the social welfare of the common people. 

2. Imbalanced regional development: Industries requiring huge investment but yielding low returns are not taken over by the private sector.

Miranda’s appeal lies in her sweet innocence, gentle nature and pure selfless love for Ferdinand. Referring closely to the text bring out the truth of the statement.

Answer»

It is a true estimate of Miranda that her appeal lies in her sweet innocence, gentle nature and pure selfless love for Ferdinand. This is seen when Miranda believes that people have perished in the shipwreck and she says “O, I have suffered with those that I saw suffer.” She further states, “O the cry did knock against my very heart!” and wishes if “I had been any gou of power, I would have sunk the sea within the earth; or ere, it should the good ship so have swallowed and the fraughting souls within her.”

When Miranda meets Ferdinand for the first time, she says, “What is’t a spirit?” She says to her father “Believe me Sir, It carries a brave form; but tis a spirit”, as she had so far only seen her father and Caliban. She takes Ferdinand to be a spirit but Prospero tells her that he is a human being and she falls in love, i.e., love at first sight. She finds Ferdinand to be noble, but is shocked to see her father behave in a strange manner and requests him to be kind and gentle towards him.

Miranda is convinced that Ferdinand is one in whom “Nothing” can dwell in such a temple. When Prospero orders Ferdinand to be obedient to his commands, Miranda pleads for him to her father, “Dear father, Make not too rash a trial of him, for He’s gentle and not fearful.” On being rebuked by her father, she implores mercy on behalf of Ferdinand and says, “Sir, have piti,: I’ll be his surety”. It is an example of her innocence.

She tries to convince Ferdinand by saying, “my father’s of a better nature, sir, than he appears by speech.” When her father says that there are better-looking men in the world than Ferdinand, she says, “My affections are then most humble; I have no ambition to see a goodlier man!”

On seeing Ferdinand carrying logs of wood, against the orders of her father, she goes to meet him and is even willing to carry that for him. She finds the task so hard and laborious that she remorses by saying, “when this (logs) bums I will weep for having wearied you,” and then she asks him to take some rest.

Miranda is an example of innocence and straightforwardness. Her conversation with Ferdinand lacks cunningness and shrewdness. She is overjoyed when told that Ferdinand also loves her, and she considers herself to be very lucky to have his love as a great reward.

Read the following extract and answer the questions that follow: Economic Times, September 4th, 2012Terming payment of taxes as a ‘mark of civilisation’, Finance Minister P. Chidambaram has assured that authorities will not “rashly” implement controversial retrospective tax rules while once again promising a non-adversarial tax regime for all taxpayers. It is the second time in less than a week that Chidambaram has given assurance of a stable and fair tax regime, after the tax department attracted criticism for ushering in what some have called a “raid raj” and for introducing a series of measures industry and investors have slammed as retrograde.1. Define direct tax. Give two examples.2. State how a direct tax can foster social consciousness. 3. What is meant by a progressive direct tax? How does its imposition bring about equity? 4. State two demerits of direct tax.

Answer»

Case Study:

1. The tax paid by the person on whom it is legally imposed is called direct tax. In other words, Taxes imposed on receipt of income are called direct taxes. 

Example: 

1. Income Tax. 

2. Capital Gain Tax.

2. Direct tax can foster social consciousness as person knows that he is paying a tax he feels conscious towards his rights. He claims the right to know how the government uses his money. Civic sense is thus developed. He behaves as a responsible citizen.

3. Taxes in which the rate of tax increases, with the increase in tax base are called progressive direct taxes.

Progressive tax: A tax is called progressive when the rate of taxation increases as the tax payer’s income increases.

Exaniple: 

Income tax. A direct tax is equitable in the sense that it is levied according to the taxable capacity of the people. The rate of direct taxes, like the income tax, can be fixed in such a way that the higher the income of a person, the greater is the tax rate.

4. Two demerits of direct tax:

1. Inconvenient: The greatest drawbacks of direct taxes is that they put the taxpayer to a lot of botheration and inconvenience. Sometimes, the taxpayer is called to pay the entire tax in one installment. 

2. Evadable: By submitting false return of income, some people evade the tax. That is why a direct tax is called as ‘A Tax on Honesty’.

5463.

Briefly explain why direct taxes foster civic consciousness among people.

Answer»

What steps did the Congress Government take after the imposition of Emergency by Indira Gandhi in 1975 ?

Answer»

At 6 a.m. on 26th June, 1975, members of the Union Cabinet were faced with the fact that an Emergency had been declared. The first step the Congress Government took was to jail leaders and legislators of opposition ‘ parties, student activists, trade unionists or anyone with the slightest connection to the Jana Sangh, The Congress (O), The Socialists or other groups opposed to the Congress including Jayprakash Narayan, Morarji Desai and the Rajmatas of Gwalior and Jaipur. 

Thousands were arrested under MISA- Maintenance of Internal Security Act. The Prime Minister said that there was a need for a ‘New Spirit of Discipline and Morale’. Government copywriters began to churn out slogans such as ‘Discipline Makes the Nation Great’. ‘Talk Less, Work More’, ‘Be Indian, Buy Indian’, “Efficiency is our Watchword”. The New Economic Programme was put through. The slogan was “Garibi Hatao”. The Prime Minister offered the ‘20 Point Programme for Economic Progress’ which promised a reduction in prices of essential commodities, speedy imple-mentation of land reforms, the abolition of indebtedness and of bonded labour, higher wages for workers and lower income taxes for the middle class. 

A series of Constitutional Amendments were passed. The 38th Amendment passed on 22nd July, 1975 barred Judicial Review of the Emergency. The 39th Amendment stated that the election of the Prime Minister could not be challenged by the Supreme Court, but only by a body constituted by Parliament. The Supreme Court, too, supported the Government by ruling that detentions without trial were legal under the new dispensation. The 42nd Amendment gave unprecedented powers to the Parliament. It could now extend its own term. Laws passed by the Parliament were immune from judicial scrutiny and strengthened the powers of the Center over the State. 

In January 1976, when the term of the DMK Government ended in Tamil Nadu, the Center ordered President’s Rule. The same was applied to Gujarat. This is how the Congress made itself supreme all over India. 

Most importantly, freedom of the Press was curbed. A system of pre-censorship was put in place whereby editors had to submit for scrutiny and approval of any article that criticized the Government. There were guidelines as to what constituted and what did not constitute as news. Even jokes and cartoons tinged with satire were forbidden. 

The Congress Government supported the programme of Sanjay Gandhi who formulated a 5-Point Programme to complement his mother’s 20-Point Programme. These dealt with family planning, afforestation, abolition of dowry, removal of illiteracy and slums. It was his forced sterilization programme and indiscriminate bull dozing of slums that finally led to the downfall of Indira Gandhi and the Congress Government.

How does the state fulfill the following socio-economic objectives? 1. Reducing income inequality. 2. Promoting industrial growth. 3. Environmental protection.

Answer»

1. Reducing income inequality: State fulfill the objective of reducing income inequality by taxation policy, the government makes it sure that the burden of tax is not falling on the poor section of the society. Similarly, when the government spells expenditure policy, it always attempts to benefit the lower income group of society.

In the context of the Arab-Israeli conflict in the Middle East, discuss the following:The circumstances that led to the Oslo Peace Accords (1993), its terms and impact

Answer»

Camp David Accord (1979) was condemned by PLO and most of the Arab states except Sudan and Morocco. 

President Sadat was assassinated by some extremist Muslim soldiers. They believed the Arabs had been betrayed by him by signing the Camp David Accord with Israel and trying to make peace with them. However, Sadat’s successor Hosni Mubarak also decided to continue with the Camp David Accord. 

Iraq-Iran war occupied the Arabs for few years and Arab-Israeli feud got overshadowed. 

Tensions arose one again when there was massive demonstration by the Palestinians who lived as refugees along Gaza Strip and the West Bank. They protested against repressive Israeli rules and policies and the brutal behaviour of the Israeli army in the refugee camps in the occupied territories. Israelis tried to clamp down the unrest with tough measures but it earned them condemnation from the UN and rest of the world. 

America kept pressuring both the nations to settle for peace. Situations changed after election in Israel in June 1992. Yitzhak Rabin, the new Prime Minister of Israel and PLO leader Yasser Arafat both agreed for lasting peace. 

This led to the Oslo Peace Accord of September 1993. The main terms of this treaty were: – 

• Israel formally recognized PLO. 

• PLO recognized Israel and committed , to give up terrorism. 

• The Palestinians were to be given limited self-rule in Jericcho, on the West Bank and in part of the Gaza Strip, areas that were occupied by Israel since the 1967 war. Israeli troops would be withdrawn from these areas. The areas would be ruled by a Parliament or Palestinian Council of 88 members that were to be elected in 1966 by all West Bankers and Arab residents of Jerusalem aged over 18. 

• Around 6000 Palestinian prisoners held by Israel were to be released in three phases. 

The leaders of different countries welcomed this bold attempt and hoped that it would bring peace. 

There were many extremists of both sides, who were ashamed of this treaty and claimed that the leaders were guilty of this surrender. Yitzak Rabin, the Prime Minister of Israel was assassinated by a right wing extremist. 

King Hussein of Jordan made an official visit to Israel for the first time, 1200 Palestinian prisoners were released, and talks went on between Syria and Israel. 

Elections were held as promised. Yasser Arafat became the Palestinian President with huge majority. 

However, tensions continue between the Arab states and Israel and there are often bomb shelling and attacks.
