1.

The function sin^(2)(omegat) represents :

Answer»

a periodic, but not simple harmonicmotion with a PERIOD`2pi//omega`
a periodic, butnot simple HARMONIC motion witha period `pi//omega`
a simple harmonic motion with a period `2pi//omega`
a simple harmonic motion with a period `pi//omega`

SOLUTION :`sin^(2) WT=(1-cos2" wt")/(2)=(1)/(2)-(1)/(2)cos2` wt
`implies` Motion is periodic but not SHM.
So the correct CHOICE is (b).
