Question

A pendulum oscilates 50 times in 6 seconds, find its time period and frequency

Answer 1

the pendulum oscillates 50 times in 6 secs.
so time taken to oscillate once= 6/50 secs = 0.12 secs
so time period of the pendulum is 0.12 secs.
frequency = 1/time period= 1/0.12 Hz = 8.33 Hz [Answer].

Answer 2

Answer:

the pendulum oscillates 50 times in 6 secs.

time period= 6/50 secs = 0.12 sec.

frequency = = 50/6 = 8.33 Hz
