Averaged over a year in the central United States radiation from the sun transfers about 200 WTH square meter of the earth surface if a house is 10m long by 10 M wide how much solar energy falls on the house each second

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

Iwould have to say sorry i can't elaborate more. hope this though!

The big glowy thing is called the sun it is a star in our galaxy and is over 1 million degrees

It is increased due to the doppler effect. (apex)
