Codes:
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
32. Assertion. There is no difference between distance and displacement.
Reason. Distance and displacement have same units.
33. Assertion. When final position of a body coincides with its initial position, the body is surely at rest.
Reason. This is because distance is scalar and displacement is vector.
34. Assertion. Average velocity = (initial velocity + final velocity) / 2
Reason. This happens when velocity of the body is changing at a constant rate.
35. Assertion. In uniform motion, the average and instantaneous velocities have the same value.
Reason. In uniform motion, the velocity of the object increases uniformly.
36. Assertion. Displacement of a body may be zero when distance travelled by it is not zero.
Reason. Displacement is a scalar quantity and distance travelled is a vector quantity.
37. Assertion. A car moving with a speed of 35 m/s takes U-turn in 5 seconds without changing its speed. Average acceleration is 7 m/s².
Reason. Acceleration = change in velocity / time taken.
38. Assertion. Distance and displacement represent the same thing.
Reason. Both have same units.
39. Assertion. Distance is scalar.
Reason. Displacement is vector.
40. Assertion. Distances can be added algebraically.
Reason. Displacement can be added vectorially.
41. Assertion. When a body travels 100 m east and then 30 m west, its displacement is 130 m.
Reason. Displacement is vector.
42. Assertion. When a body travels 100 m east and then 30 m west, total distance travelled is 130 m.
Reason. Distance is scalar.
43. Assertion. A body travels 100 m north and then 100 m south. Net displacement = 0, total distance = 200 m.
Reason. Distance is scalar and displacement is vector.
44. Assertion. Distance travelled may not be zero even when displacement is zero.
Reason. This is because displacement is vector and distance is scalar.
45. Assertion. When final position of a body coincides with its initial position, displacement is zero; distance travelled is not zero.
Reason. Displacement is a vector.
46. Assertion. Displacement may be zero when distance travelled is not zero.
Reason. Displacement is scalar and distance is vector.
47. Assertion. A car moving at 36 km/h takes a U-turn in 5 seconds. Average acceleration is 4 m/s².
Reason. Acceleration = rate of change of velocity.
