31. Turpentine oil is extracted from which tree?

(1) Teak
(2) Oak
(3) Rose-wood
(4) Pine

Correct Answer: (4) Pine

Solution:Turpentine oil is a fluid that is mainly obtained by the distillation of resin derived from the pine trees.

32. In which part of the Earth value of "g" is maximum?

(1) Equator
(2) Poles
(3) Tropic of Capricorn
(4) Equal at every where

Correct Answer: (2) Poles

Solution:Because the Earth is not round completely, the diame ters of the earth decrease when we move from the equator towards the poles. Because the value of R is more on the equator, therefore, the value of G is less on the equator. whereas the value of R is less when value of G is less.

33. Which organ is called "Graveyard of RBC?

(1) Spleen
(2) Liver
(3) Heart
(4) Kidney

Correct Answer: (1) Spleen

Solution:Spleen is known as 'Graveyard of RBC. because it expels the old red blood cells and maintains the Blood reserves.

(3) Calcium
(4) Zirconium

Correct Answer: (1) Cadmium

Solution:Greenockite is a rare mineral and it is the only actual ore of cadmium, though it is the most common mineral.

35. Rain drops are spherical in shapes due to.

(1) Capillarity
(2) Gravity
(3) Surface Tension
(4) None of these

Correct Answer: (3) Surface Tension

Solution:Due to the surface tension of water, drops of rain seem to be spherical.

36. Pulsars are.

(1) Stars moving towards the Earth
(2) Stars moving away from Earth
(3) Rapidly spinning neutron Stars
(4) High temperature stars

Correct Answer: (3) Rapidly spinning neutron Stars

Solution:Pulsar is a rapidly spinning neutron star, which emits electromagnetic radiation.

37. Angle of friction and angle of repose are.

(1) Equal to each other
(2) Not equal to each other
(3) Proportional to each other
(4) None of these

Correct Answer: (1) Equal to each other

Solution:The friction angle is the angle formed by the resultant force of the normal reaction force and friction caused by the beginning of the movement of an object. The angle given by the cross reversal of the friction Coefficient between the two surfaces are same.

38. The mode of respiration in amphibians is.

(1) Buccal
(2) Cutaneous
(3) Lung
(4) All of the above

Correct Answer: (4) All of the above

Solution:Three different methods are used for respiration by amphibians.

1. Cutaneous

2 Buccal

3. Pulmonic

39. Baking soda is

(1) Sodium Carbonate
(2) Sodium Bicarbonate
(3) Sodium Sulphate
(4) Potassium Carbonate

Correct Answer: (2) Sodium Bicarbonate

Solution:Sodium bicarbonate (NaHCO₃) is known as baking soda. It is used mainly in baking in the form of a fermenting substance.

40. Acid rain contains

(1) Sulphuric acid only
(2) Hydrochloric acid only
(3) Nitric acid and Hydrochloric acid
(4) Both Sulphuric acid and Nitric acid

Correct Answer: (4) Both Sulphuric acid and Nitric acid

Solution:Acid rain contains sulphuric acid (H₂SO₄) and nitric acid (HNO) they are formed by the use by Electronic equipments and combustions of fossil fuels.
