Question

The time period of a simple pendulum is 20 s, its frequency is

Answer 1

Explanation:

When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds. Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz. Therefore, the frequency of that pendulum is found to be 0.5 Hz.

Answer 2

Answer:-

6

When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds. Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz. Therefore, the frequency of that pendulum is found to be 0.5 Hz.
