Adiver dives off of a raft - what happens to the diver? the raft? how does this relate to newton's third law? action force: reaction force:

1.      The diver transfers forward and dives into the water.

2.      The raft transfers backwards in the water for the reason that of the reaction force.

3.      The action force is the diver pushing off of the raft; and the

4.      reaction force is the raft pushing back on the diver (causing the diver to go forward and into the water)

a.) travels faster in solids because the particles are closer together.
