Question

a pendulum oscillates 60 times in 5 seconds find its time period and frequency​

Answer 1

Answer:

Frequency = (Value Variation) / (Duration) Frequency.

                   = (60/5) = 12Hz.

Explanation:

The pendulum oscillates 60 times in 5 secs.

so taken taken to oscillate once =5 / 60 secs =0.1 secs

so time period of the pendulum is 0.1 secs.

Frequency =1/timeperiod=1/0.1Hz =12 Hz

We get, 12Hz.
