Question

please answer my question​

Answer 1

Answer:

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.

Hope this would help u..!✨

Answer 2

Answer: Number of oscillations= 10

Time taken = 20 seconds

Time period = time taken/ number of oscillations

= 20/10

= 2 seconds

Frequency of its oscillations = 1/time period

= 1/2

= 0.5 Hertz

Therefore, the time period = 2 seconds and the frequency = 0.5 Hertz.
