Question

simple pendulum completes 22 oscillations in 20 seconds, so the time period of the pendulum is ______. *

1) 2.1 s
2) 1.2 s
3) 1.0 s
4) 1.1 s
​

Answer 1

Answer:

Answer =1.0S is the correct answer

Answer 2

Correct answer

When a simple pendulum makes 10 oscillation in 20 seconds

The time for each oscillation = 20/20 = 2 second

Hence , as the time period is calculated to be 2 seconds , the frequency of oscillations = 1/T = 1/2 = 0.5 Hertz

Hope it's help you !
