Question

6. If a distance - time graph for the motion of a body in a line is parallel to x- axis then b. the body is moving with a constant speed.

Answer 1

Answer:

According to distance - time graph,

Distance-time graph means that Distance is the y axis, and Time is the x axis.

If we draw a line that is parallel to the x axis, then it's slope is null .

Using the first derivative of motion, change in distance is velocity.

∆x=v

Since the change in distance is zero, because the slope is zero, we can deduce that the velocity is also zero.

Hence, Option B is correct.

Answer 2

Explanation:

if the line is parallel to the x axis then the car is not moving i.e it covers zero distance in increasing interval of time... so obkect is at rest ......hope this will help u surely please follow me please
