Question

A simple pendulum takes 50 s to complete 25 oscillations. Its time period and frequency are
2 Hz , 0.5 s
2 s, 0.5 Hz
5 Hz, 0.2 s
58, 0.2 Hz​

Answer 1

Answer:

ANSWER

For 15 oscillation it takes 30 sec

For one oscillation Tme period = 30/15 = 2sec

Frequency = 1/ Time period

=1/2=0.5 Hz

Answer 2

Answer:

For 25 oscillations it takes 50 second

For one oscillations time period = 50/25

frequency = 1/ time period

1.2=0.5 Hz
