Answer 1

Answer: The frequency of a pendulum is
`0.2 s^(-1)`.

Step-by-step explanation:

Time period is defined as the time required to produce complete wave.

As we know that the frequency and time are inversely proportional to each other.

That means,

`\\u =(1)/(T)`

Where,

`\\u` is frequency of pendulum

T is time period

Given:

Time period = 5 seconds

Now putting all the given values in the above formula, we get the frequency of the pendulum.

`\\u =(1)/(T)\\\\\\u =(1)/(5s)\\\\\\u =0.2s^(-1)`

Therefore, the frequency of a pendulum is
`0.2 s^(-1)`.
