Question

A PENDULUM OSCILLATES 30 TIMES IN 3 SECONDS. FINDS 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

Answer 2

Answer:

the time period is 3/30=1/10

frequency is 30/3=10Hz.
