Use the drop-down menus to complete the statements. The amount of energy a wave carries corresponds to its
vis equal to the number of wavelengths that pass a fixed point in a second.
Frequency is typically expressed in

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

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.
