Question

In the following questions, the Assertion and Reason have been put forward. Read the statements carefully and choose the correct alternative from the following:
(a) Both the assertion and the reason are correct and the Reason is the correct explanation of the assertion.
(b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
(c) Assertion is true but the Reason is false.
(d) The statement of the Assertion is false but the Reason is true.
(e) Both assertion and reason are false.

1.ASSERTION- Velocity may be variable even if speed is constant.
REASON-Velocity is a vector quantity and speed is a scalar quantity.
2.ASSERTION- The displacement of the body is zero and distance of the body is non
zero when final position coincides with the initial position during its
motion.
REASON-Displacement depends upon the actual path traversed by the object during
motion.
3.ASSERTION- Distance-time graph of body is a straight line and motion of the body
is uniform speed.
REASON-Slope is the gradient of distance-time graph.
4.ASSERTION- A fixed point with respect to which the given object changes its
position is the reference point.
REASON-The motion of the body is not relative to the reference point.
5. ASSERTION- A body moving in a circular path has uniform velocity.
REASON-Velocity changes as the direction of motion changes.
6. ASSERTION: Displacement is a vector quantity.
REASONING: Displacement is described by magnitude but not by direction.

Answer 1

Answer:

b is the answer

Explanation:

Answer 2

Answer:

snswer is a

Explanation:

because velocity is a vector quantity it varies with change in direction
