Compare the expressions for the energy stored in an inductor and the energy stored in a capacitor. Select the choices that explain the similarities indicated by the two expressions.

a. Calculating the energy stored in each device involves multiplying by a factor of 1/2.
b. The expressions are equivalent because LC= Δt^2
c. The proportionality constant used in each expression is determined by the physical properties of the circuit element.
d. The energy stored in each device is directly proportional to the square of a quantity involving charge.
e. The energy stored in each device is directly proportional to a quantity related to current.
f. Each device stores an amount of energy that is inversely proportional to the physical dimensions of each device.

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.
