Question

A pebble is thrown into a calm lake, ripples are formed from the center and move outward. The water particles in the lake travel in a circular pattern that moves up and down on the surface of a lake, and the energy travels A) diagonally. B) downward. C) horizontally. D) upward.

Answer 1

Answer: The option (C) is correct. The energy travels horizontally.

Explanation: When the pebble is thrown into a calm lake, there will be disturbance in the lake. The ripples are formed from the center and move outward because the energy is carried out from particle to particle.

The distribution of the energy among the particles starts from center and it will carry out outward. This disturbance will occur horizontally.

Therefore, the energy travels horizontally.
