Question

A pendulum makes 100 oscillations in 20 seconds. Calculate its time period and frequency​

Answer 1

Answer:

Number of Oscillation in 20 sec = 100

Frequency = Number of Oscillation / time

=> Frequency = 100 / 20

=> Frequency = 5 Hz

Time period = 1 / Frequency

=> Time period = 1 / 5

=> Time period = 0.2 seconds
