A small mass of 0.2kg is weld round in a horizontal circle at the end of the stream of length 0.5m at a constant angular speed of 4radius per sec calculate the angular speed of the object

lexy is right because she has the labeled s

0.19 m/s and 0.45 m/s

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.
