1. An automobile with a mass of 1000 kg accelerates when the traffic light turns green. If
the net force on the car is 4000 N, what is the car's acceleration?

25 because I said so and yeah

its a 5.5 n

glad that

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.
