-- The source of most of the energy that radiates from the sun is nuclear energy.
-- Most of the energy that radiates from the sun is electromagnetic energy.
-- Heat energy is part of the electromagnetic energy that radiates from the sun.
Other parts include radio, microwave, visible light, ultraviolet, and X-ray energy.
Gravity increased the downward speed (or decreases the upward speed) by 9.8 m/s every second.
21.2/9.8 = 2.2 seconds
I don’t know what your talking about. ?!?!?!?
This type of wave is a transverse wave, or an S wave (secondary wave)
Then the waves (and the energy they carry) are completely reflected from the surface of the impenetrable medium.
Example:
An ordinary mirror is a sheet of glass with a thin layer of aluminum
or silver stuck to the back of the glass. Light waves have no trouble
traveling through the glass, but they can't get through the silver layer
on the back of it. So the waves completely bounce off of the silver, and
go back through the glass in the direction they came from.
