Answer:
Explanation:
The object is moving to and fro about its mean position
and the equation for its displacement is given as
now in one complete time period we know that the the object will complete its one oscillation
So the change in the position of the object in one complete time period will be ZERO
so here we can say that
since change in position is zero
so displacement = 0
