Question

A pendulum completes 30 cycles every minute. What is the frequency of the pendulum?

Answer 1

For this case we have that by definition, the frequency is given by the number of cycles that are formed in a second.

According to the statement we have:

Cycles: 30

Time: 1 minute = 60 seconds

Thus, the frequency is:

`f = \frac {30} {60} = \frac {3} {6} = \frac {1} {2} = 0.5`

Thus, the frequency of the pendulum is
`0.5 \ Hz`

Answer:

`0.5 \ Hz`
