Newton’s second law of motion states that when a force acts on an object, the object’s acceleration is equal to the net force divided by the object’s mass, and is in the same direction as the net force.
I can't see numbers here, so here are all the answers:
1) the frequency is c/λ = 3e8/556e-9 = 5.39e14Hz
2) light travels at <span>299,792,458 m/s. So in nanoseconds it's 0.299792458m. This is about 1/3 of a meter which is about one foot.
3) length is L = ct = (</span>299,792,458 m/s)(6e-15) = 1.799e-6m or 1.799μm

Answer: A- removes fertile topsoil
A wind erosion is a natural phenomena in which the surface and subsurface layers of soil is removed and displaced by the action of wind. It occurs in flat, bare areas, having dry and sandy soil or any place where the soil is loose, dry and fine in texture.
The wind erosion removes the superficial layers of soil that are fertile, hence reduces the soil fertility of soil.
