A forestry worker accidentally strikes a pipe with the end of a
pickaxe while trying to dig a hole. If
the pickaxe strikes with a force of
2000 N and the end of the pickaxe
measures 0.02 m by 0.01 m, how much
pressure is exerted on the pipe by the
pickaxe?

what type of charge does it have? negative

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.
