1. A Pendulum oscillates 90 times in 30 seconds Find its time period and frequency
​

Answer 1

Answer

The pendulum oscillates 60 times in 6 secs.

so taken taken to oscillate once =6/60 secs =0.1 secs

so time period of the pendulum is 0.1 secs.

Frequency =1/timeperiod=1/0.1Hz =10 Hz

We get, 10Hz.
