Detailed Solution

Concept- The principles and uses of rotational motion in physics can be used to address the given problem. Additionally, it is possible to perform the fundamental analysis that must be done in order to visualise the example of our everyday lives.
If an object has a circular motion along a given path with some amount of velocity along the circular path—known as the angular velocity—then the object is said to be in rotational motion. And angular displacement is the term used to describe the length of path travelled by a single revolution.
Everyday uses for the rotational speed can be found in the following popular applications, which are described below:
1. The ceiling fan's blades are turning around.
2. The movement of bicycle, motorcycle, and other vehicle wheels.
3. The satellite's movement in relation to Earth's and other planets' orbits.
4. The earth's axis is rotating.
5. How the DVD player rotates the CD or disc.
Hence, option 4 is correct.
