D

Explanation: 

Detailed explanation-1: -The Newton’s cradle is a device that demonstrates the conservation of momentum and the conservation of energy with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.

Detailed explanation-2: -Thus, if two balls are lifted into the air on one end of the device and released, then two balls on the opposite end will swing in response. This continuous clicking of balls is also proof of Newton’s law of the conservation of energy, which states that energy can’t be created or destroyed but that it can change forms.

Detailed explanation-3: -Newton’s Cradle visualizes an elastic collision by allowing students to see the mass as a number of balls, and the speed as the height the balls travel.

Detailed explanation-4: -The balls lose energy to many things – they lose energy to the air as they move through it (air friction), they make sound energy when they collide, and they lose energy to heat upon collision. Each of these factors “takes away” energy from the ball – as the ball loses energy it slows down and eventually stops.

Detailed explanation-5: -Why do Newton’s Cradle balls stop? As the balls on either end swing, eventually, the balls lose energy to many things. This includes air due to air friction, sound when they collide and finally heat upon collision.
