In simple harmonic motion, the acceleration is proportional to In simple harmonic motion, the acceleration is proportional to:. a. the amplitude.
b. the velocity.
c. the frequency.
d. the displacement.
e. all of the above

e. all of the above

Explanation:

In simple harmonic motion, the acceleration is given as;

a = -ω²x = -(2πf)²x

where;

ω is the angular velocity

f is the frequency

x is the displacement

A is the amplitude

Thus, In simple harmonic motion, the acceleration is proportional to the amplitude, velocity, frequency, and displacement.

The correct option is E.

"all of the above"

3. dark matter

empty space could also be a simple vacuum
