Question

Answer with full reasons

Answer 1

Answer:

Option b

Explanation:

Because, diff. Of velocity gives acceleration...

And diff. Of distance gives velocity......

Answer 2

(B)

In uniform circular motion, the speed of the body is constant.

Acceleration is a vector depending on magnitude and direction.

The acceleration is constant and zero in magnitude as the speed of the body does not change in at all.

But the direction changes continuously and this direction is inwards towards the centre of the circle.

Take an example. When you are cycling on a circular track, don't you change direction continuously to stay on the track? You cannot keep the handle straight as you need to change direction towards the inner part of the path.

Thus, option B is correct.

Please mark this as the brainliest answer. I've spent a lot of time answering this question to make it look like it's from a textbook. A brainliest will mean a lot to me.
