A pendulum oscillates 40 times is 4 seconds. Find its time period and frequency.

Explanation

To solve the problem, we need to find the time period and frequency of a pendulum that oscillates 40 times in 4 seconds.

### Step 1: Calculate the Frequency
Frequency (f) is defined as the number of oscillations per second. We are given that the pendulum oscillates 40 times in 4 seconds.

To find the frequency, we can use the formula:
\[
f = \frac{\text{Number of oscillations}}{\text{Time in seconds}}
