Answer 1

Answer:

2 * r will be the displacement

Answer 2

Explanation:

It is a vector quantity. For example, if a body moves along a circle of radius r and covers half the circumference, then displacement is given by s=2r.Since distance is the length of path covered therefore it will be equal to half the circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distance between initial and final point. Therefore it will be equal to the diameter or r+r=2r.
