31. Which of the following are included in the definition of Narrow Money?

1. Currency with the public
2. Demand deposits
3. 'Other' deposits with Reserve Bank of India
4. Banker's deposits with Reserve Bank of India

Select the correct answer using the codes given below.

Correct Answer: (b) 1 and 2
Solution:Options (1), (2) and (3) are included in the definition of Narrow Money. The Narrow Money refers to the category of money supply that includes all the real money held by the Central Bank. It refers to Physical money such as coin, currency, demand deposits and liquid assets that are easily accessible to Central Bank. It is called Narrow Money because easily can convert into cash and has high liquidity.

32. Which of the following is/are the effects of devaluation or depreciation of currency?

1. It leads to increase in imports and decrease in exports.
2. It leads to increase in exports and decrease in imports.
3. It leads to increase in domestic inflation.
4. It leads to decrease in domestic inflation.

Select the correct answer using the codes given below.

Correct Answer: (c) 2 and 3
Solution:Options (2) and (3) are the effects of devaluation or depreciation of currency. Depreciation of currency means that more rupees are required to buy a dollar. Accordingly exports are expected to increase, while imports will take a hit. It can also increase the domestic inflation.

33. Which one of the following taxes is not subsumed under the Goods and Services Tax in India?

Correct Answer: (d) Taxes on Petroleum and Petroleum Products
Solution:Taxes on Petroleum and Petroleum Products are not subsumed under GST (Goods and Services Tax). It is an indirect tax imposed on the supply of goods and services.

34. The following diagram shows a pendulum at different positions. Which one of the following statement is true?

Correct Answer: (c) The pendulum has minimum potential energy at position R.
Solution:For the given diagram which shows a pendulum at different position, the statement (c) is true. In this the pendulum has minimum potential energy at position R and maximum potential energy at position P and T. Because the position of maximum, displacement of the pendulum. the potential energy is maximum.

35. In which of the following media is the speed of sound the maximum ?

Correct Answer: (b) Stainless steel
Solution:Among the given options, the speed of sound is maximum in stainless steel. Sound is a mechanical wave because they pass through a physical medium like air, liquid and metal. The amplitude of sound wave depends on the force with which an object is made to liberate. So, greater amplitude wave have more energy and greater intensity.

36. A charged particle moves through a magnetic field B with a velocity v. Which one of the following statements is true for the force (F) experienced by the particle?

Correct Answer: (c) F is maximum when v and B are perpendicular to each other.
Solution:A charged particle moves through a magnetic field B with a velocity v. Then force (F) is maximum when v and B are perpendicular to each other.

∵ A force (F) on charged particle given by
F = qv Bsinθ
If, theta = 90° than sin 90° = 1
So, F = quB which is maximum.

37. Which one of the following is the correct relation between Celsius and Fahrenheit temperature scales? (Symbols carry their usual meanings)

Correct Answer: (d)
Solution:

38. Which one of the following statements is correct regarding the travel of a light beam from a rare to a dense medium?

Correct Answer: (a) A light beam travelling from a rare medium to a dense medium slows down and bends towards the normal.
Solution:Statement (a) is correct. A light beam travelling from a rare medium to a dense medium slows down and bends towards the normal is correct regarding the travel of a light beam from a rare to a dense medium. Here the amount of bending the light beam depends on the refractive index of both media.

39. In which one of the following cases do both physical and chemical changes take place?

Correct Answer: (a) Burning of candle
Solution:In Burning of candle, both physical and chemical changes take place. Freezing of water is a physical change and cooking of food and rusting of iron both are chemical change.

40. Which one of the following statements is correct about diamond and graphite ?

Correct Answer: (b) Diamond is hard but graphite is smooth and slippery.
Solution:Statement (b) is correct about diamond and graphite. Diamond is hard but graphite is smooth and slippery.
