As the energy of a wave moves through the water, what happens to the water particles themselves?
a. they are carried away.
b. they sink to the bottom.
c. they move up and down, but do not move forward.
d. they slowly move backward.

As the energy of a wave moves through the water, the water particles move up and down, but do not move forward. The correct option among all the options given in the question is option "c". The wave itself starts moving forward, but the particles remain in a stable condition without moving along with the waves.

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way

2. they have negligible mass.
