Answer:

B. 0.0254m

Step-by-step explanation:

A is the amplitude of the oscillation, i.e. the

maximum displacement of the object from

equilibrium, either in the positive or negative x-direction. Simple harmonic motion is repetitive.

The period T is the time it takes the object tocomplete one oscillation and return to the startingposition.

d = 2A = 2×0.0127
