Question

In a watch P. E of wound spring is converted into. a. Chemical energy

b. Kinetic energy

c. Mechanical energy

d. Electrical energy​

Answer 1

Answer:

b

Explanation:

kinetic energy because when the wound of watch is come in motion

Answer 2

● In a watch potential energy of wound spring is converted into to kinetic energy and this energy makes gear move or rotate.

● An wound up watch spring has potential energy that is stored energy.

● Work was done to wind the spring. When running, a watch changes over the potential energy of the spring into dynamic kinetic energy of the apparatuses.

● At the point when a watch runs down, its energy has been changed over to heat energy and sound energy.
