Question

a pendulum oscillates 40 times in 4 second find its time period and frequency​

Answer 1

Answer:

Frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency is = 40 vibrations /4 seconds= 10 Hertz.

Answer 2

A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency. Frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency is = 40 vibrations /4 seconds= 10 Hertz.
