Question

The period of oscillation of a simple pendulum
which takes 38 s for 20 oscillations is
a) 38s b) 76 c) 3.85 d) 1.9 s​

Answer 1

Answer:

1.9

Explanation:

period =38/20=1.9s

Answer 2

Answer:

Time Period = (Total time is taken)/ (Number of Oscillations)

Given: - 20 oscillations taking 38s to complete.

Therefore 1 oscillation will take = (38)/ (20) sec = 1.9 second

Therefore, 1.9s is the time period of the pendulum.
