Question

A pulse traveled the length of a stretched spring.

The pulse transferred
(1) energy, only
(2) mass, only
(3) both energy and mass
(4) neither energy nor mass

Answer 1

So we want to know to what is the pulse transformed that traveled the length of a stretched spring. So a pulse is a part of a mechanical wave, and mechanical waves are energy transfer trough some medium, in this case a stretched spring. So the correct answer is (1) energy. The pulse cant be transferred into mass.

Answer 2

Answer: The correct answer is energy only.

Step-by-step explanation:

Wave is a disturbance which carries energy from one particle to another particle. It is a continuous disturbance.

Pulse is a single disturbance. It is non repeating single bump. It carries energy only. For example, a person is holding one end of the rope. He is moving that end. The pulse will create through the rope.

A pulse travels the length of a stretched spring. The pulse transfers the energy only.

Therefore, the correct option is (1).
