Explanation:
Pendulum a has frequency 3 hz and B has 2 hz.
Frequency = Total oscillations / Total Time
Pendulum A
15 oscillations in 5 seconds (Given)
Number of oscillations in 1 second will be -
= 15/5
= 3 Hz
Thus, frequency = 2.8 Hz
Pendulum B
8 oscillations in 4 seconds (Given)
Number of oscillations in 1 second will be -
= 8/4
= 2 Hz
Frequency = 2 Hz
Therefore, Pendulum A has a higher frequency
