Question

When a wave hits an ocean buoy, it bobs up and down
so that the movement over time can be described by a
sine function.

Suppose the buoy travels 1 meter from its high point to
its low point and completes 20 cycles per second.

Which equation BEST represents h, the height of the
buoy in meters relative to its position on a calm ocean,
as a function of t, the time in seconds?

h = sin(20nt)
h = sin(40nt)
h= 20 sin(2nt)
h=0.5 sin (40nt)
