Question

A simple pendulum completee 40oscillations in on minute find it's frequency and it's time periods

Answer 1

Answer:

frequency is the no. of oscillations per one second. so, for 60sec, it undergoes 40 oscillations. then for one second, it undergoes 40/60=0.6 oscillations.so,it's frequency is 0.6Hz.

it's time period is 2π√l/g.
