Question

A PENDULUM COMPLETES 2400 OSCILLATIONS IN 4 MINUTES. FIND FREQUENCY AND TIME PERIOD OF VIBRATION.

Answer 1

Solution:-

Given:-

Oscillation = 2400

Time period = 4 min = 60s × 4 min = 240s

In 240s = 2400/240

=> 10Hz

Frequency = 1 / time period

=> time period = 1/frequency

=> time period = 1/10 = 0.1 sec

☆Frequency = 10Hz

☆Time period = 0.1 sec

Answer 2

Answer:

The frecuquency is 2400÷ 240 = 10 Hz

And the Time period is 0.1 sec .
