I'm really bad at mechanical !
using the example of the skateboarder on the half-pipe, explain how kinetic and potential energy relate to the mechanical energy at different positions.

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

Which of the following are properties of mechanical waves? check all that apply ⭕️ particles of the medium move back and fourth, but do not move with the wave. ⭕️ the particles of the medium always move parallel to the wave motion. ⭕️ wave motion begins with a disturbance in the medium. ⭕️ waves transport energy from a source outward, away from the source.
