Question

A Pendulum makes 400 oscillations in 10 seconds. Calculate the frequency and time period of oscillation of the pendulum in milliseconds. [2 MARKS]

Answer 1

Each point: 1 Mark

1. Given that 400 oscillations are made by the pendulum for 10 sec.
We know that the number of oscillations made per second is called its frequency 400/10 =40
2. Time period = 1/ Frequency
1/40
=0.025s
=25 ms
