Which of the following conditions creates the largest waves?

a.
slow-moving wind over smooth water

b.
slow-moving wind over choppy water

c.
fast-moving wind over smooth water

d.
fast-moving wind over choppy water

D because choppy water is already a little bit of wave action and then the wind adds a lot of speed to the waves and height to the waves to meek the best waves. Hope this helped.

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.
