Question

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

Answer 1

Frequency is defined as the number of oscillations per unit time.

Time = 4 sec.

Time Period = (4/40) = 0.1 sec.

Frequency = (Number of Oscillations)/ (Time taken)

Frequency = (40/4) =10Hz.

Answer 2

Answer:

Frequency is defined as the number of oscillations per unit time. Time = 4 sec. Time Period = (4/40) = 0.1 sec. Frequency = (Number of Oscillations)/ (Time taken)Frequency = (40/4) =10Hz.
