Question

Pendulum A makes 140 Oscillations in 5 sec and pendulum B makes 10 Oscillations in 3 sec. Which has a higher frequency. Express the frequency of each pendulum in hertz.

Answer 1

Pendulum B has higher frequency.

Pendulum A-

frequency=1/time period

f=1/5=0.2Hz

Pendulum B

f=1/t

f=1/3=0.3

So, B has higher.
