A three-phase load consumes 200kVA at 0.8 pf lagging. The line-to-line voltage magnitude at the load is 2000V. The three-phase distribution line supplying this load has an impedance of .
Compute the line-to-line voltage magnitude at the sending end of the distribution line, the real and reactive power supplied at the sending end of the distribution line.

tube or goog will be great resources to find the answer to the question that you're asking

double the distance = divide strength by 4

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.
