Suppose that a copper sleeve of inner radius 2.40 cm and outer radius 2.50 cm is to be cast. to eliminate bubbles and give high structural integrity, the centripetal acceleration of each bit of metal should be 118g. what rate of rotation is required? state the answer in revolutions per minute.

d is the correct answer

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
