Question

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

Answer 1

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.

Answer 2

Answer:

Time period = 0.1 and frequency = 10Hz

Explanation:

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

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

Frequency = (40/4) =10Hz.
