The function `sin^(2)(omega t)` represents:

Options

A. A periodic, but not simple harmonic motion with a period `2pi//omega`
B. A periodic, but not simple harmonic motion with a period `pi//omega`
C. A simple harmonic motion with a period `2pi//omega`
D. A simple harmonic motion with a period `pi//omega`

Answer

B

Explanation

`sin^(2)(omegat)=(1-cos(2omegat))/(2)`
`T=(2pi)/(2omega)=(pi)/(omega)` Periodic but not SHM.
