What is the resistivity of a 10. meter wire with a 0.315 millimeter diameter if it has a resistance of 0.50 ohms? Write your answer in scientific notation with three digits and no units

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.
