An australian emu is running due north in a straight line at a. speed of 13.0 m/s and slows down to a speed of 10.6 m/s in 4.0 s.. (a) what is the direction of the bird’s acceleration? (b) assuming that. the acceleration remains the same, what is the bird’s velocity after an. additional 2.0 s has elapsed?

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.
