2. A ball is released from a vertical height of 20 cm. It rolls down a "perfectly frictionless” ramp and up a similar ramp. What vertical height on the second
ramp will the ball reach before it starts to roll back down?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Can anybody me with this? ? (picture included.)
