Answer 2

The correct answer is option (D) Rotation of Earth.

• Rotation of earth happens during a period of time i.e. 24 hrs. therefore, rotation of earth is a periodic change. The time taken by earth to rotate on its axis is fixed, and it repeats after the same time interval.
• The motion which repeats itself after equal time intervals is called periodic motion.
• Periodic changes are the changes that tend to repeat or reoccur at the same interval of time periodically.
• There are infinite examples of a periodic change like a simple pendulum, the change in the position of a simple pendulum can be periodic and sometimes it can also be categorized as cyclic change.
