Question

A pendulum oscillates 40times in 4 second . Find its time period and frequency

Answer 1

Answer:

Explanation:

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

Time period is the time required to complete one oscillation. Or it is the inverse of time period. Therefore time period = 1/10 = 0.1 seconds.
