1. Consider a square that is composed of four 100 ohm resistors connected together. A fifth 100 ohm resistor is connected across the diagonal of the square. This arrangement is called a bridge circuit. (a) A 10 V battery is connected to the two corners of the square, which are themselves connected to the 100 ohm diagonal resistor. What current flows from this battery

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.
