Question

A pendulum covers 500 oscillations in 20s then find the frequency and time period of the pendulum

Answer 1

Answer:

Explanation:

time period = time taken by no. of oscillations / no. of oscillations

                   = 20 / 500

                   = 1 / 25

                   = 0.04 sec

frequency = 1 / time period

                 = 1 / 0.04

                 = 25 Hz
