Answer:
Orbiting satellite that speeds up near the earth and slows down far away.
Explanation:
A uniform circular motion can be defined as the movement or motion a body that is in circular path and it must be in constant speed. The direction of motion of such a body can be known by taking tangent at its every position.
Now according to given options:
- CD in a CD player in spinning at a constant speed and motion is circulatory. So it is in uniform circular motion.
- The speed of satellite is varying with respect to the distance from earth, so it is not in uniform circular motion.
- The speed of jet fighter is also given (constant), So it is also in uniform circular motion.
- Merry-go-round has constant rotations per minute so it will also be in uniform circular motion.
I hope it will help you!
