1) A 42kg box is sitting on a 32° ramp. What are the forces in each direct that are keeping it still?
2) A book is left on an angle table of 35°. if the book weighs 22N and has a normal force of 18N with a force of friction of 11N, what is the net force acting on the book?

correct it is c.) b b

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.

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
