Answer 1

A miracle is an event that seems inexplicable by natural or scientific laws. In various religions, a phenomenon that is characterized as miraculous is often attributed to the actions of a supernatural being (especially a deity), magic, a miracle worker, a saint, or a religious leader.

Answer 2

The height from which the ball is dropped cannot be 10 cm, it will be 10 m as the ball is said to rebound 2.5 m.
