A bullet traveling at 300m/s strikes a log of wood and it penetrates to a depth of 0.11m, if the mass of the bullet is 1.8g, in what time does the bullet come to rest

dang that balls went far

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.
