Which equation shows the correct relationship between mechanical energy, kinetic energy, and potential energy? me = ke + pe me + ke = pe me = ke – pe me + pe = ke

ME = KE + PE

Explanation:

The sum of the kinetic energy and the potential energy is called mechanical energy.

Kinetic energy is defined as the energy possessed by the virtue of motion of a body.

The formula for the kinetic energy is given by

Where, m is the mass of the object and  be the speed of the object.

Potential energy of a body is defined as the energy possessed by the body by virtue of its position or configuration.

The formula for the potential energy is given by

Where, m is the mass of the object, g be the acceleration due to gravity and h be the height of the object.

d. air pressure decreases as altitude increases.

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.
