Question

2. A straight line parallel to time -axis on a distance-time graph tells that the object is:
a) moving with constant speed b) at rest c) moving with variable Id) in motion​

Answer 1

Answer:

(b) at rest

Explanation:

the parallel line shows that time is increasing but diatance is not

thus the object is at rest

Answer 2

Answer :

A straight line parallel to time axis on a distance-time graph tells that the object is at rest$.$

_________________________________

◈ Slope of distance-time graph gives velocity.

ATQ, slope of graph is zero it implies that, speed of particle is zero.

We know that, speed is defined as the ratio of distance travelled to the time taken.

Here, speed of particle is zero.

➝ speed = distance/time

➝ distance = 0 × time(t)

➝ distance = 0

Hence, distance covered by body is zero, indirectly body is at rest position.
