When Meagan strikes her drum, the skin of the drum moves. The kinetic energy of the skin is converted to sound energy. Which statement best explains why all of the kinetic
energy is NOT converted to sound energy?
Friction slows the movement of the drum skin.
The kinetic energy is converted to potential energy.
Some of the kinetic energy is lost as heat.
The skin of the drum absorbs kinetic energy.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
