An object revolves uniformly in a circle of diameter `0.80` m and completes 100 rev `"min"^(-1)`. Find its time period and angular velocity.

Explanation

To solve the problem step by step, we will find the time period and angular velocity of an object revolving uniformly in a circle.

### Step 1: Find the radius of the circle
Given the diameter of the circle is \(0.80 \, \text{m}\), we can find the radius \(r\) using the formula:
\[ r = \frac{\text{diameter}}{2} = \frac{0.80 \, \text{m}}{2} = 0.40 \, \text{m} \]
