A plane is traveling at 250 m/s north after being in the air for 1 hour, what is the displacement?

900,000 meters of displacement.

Explanation:

250x60x60 because it is meters per second and needs to be converted to a full hour.

the total distance traveled by the car is

30km + 49km = 79 km .

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.
