You are to launch a rocket, from just above the ground, with one of the following initial velocity vectors: (1) , (2) , (3) , (4) . In your coordinate system, x runs along level ground and y increases upward. In the following questions, you will need to rank these vectors. If multiple vectors rank equally, use the same rank for each, then exclude the intermediate ranking (i. e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all vectors rank equally, rank each as '1'.

explanation:

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.
