Determine the recoil speed of Earth if all of the inhabitants of Canada and the United States simultaneously jumped straight upward from Earth's surface. Suppose the average jump height reached by the population is 0.60 mm, the population of the two countries is about 3.46×108×108, an average mass is 50 kgkg. Mass of Earth is 5.98×1024kg×1024kg.

i believe it is b. what was the cause of the big bang

hope this !

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.
