The gravitational force between two rocks 2 x 10^-4 N. They are separated by 2m. One rock has a mass of 3 x 10^3 kg. Find the mass of the other rock

conduction, convection, radiation

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
