the time period of the pendulum is 10 seconds per minute.

Answer 2

Answer:

Hey bud,

Since the, Time period of pendulum is characterized by Time taken by the pendulum to the ratio of number of oscillations made by the pendulum.

That is ,

$time \: period \: = \frac{time}{osciallations}$

$time \: period = \frac{4}{40}$

Time period = 0.1 seconds.

$frequency = \frac{1}{time \: period}$

$frequency = \frac{1}{0.1}$

Frequency = 10 Hz

Hope that helps... : )
