Four resistors of R1 = R, R2 = 5 R, R3 = 5 R, and R4 = R/3 (R is the resistance of the first resistor and the others are related to the first resistor by some factor) are connected purely in parallel to a 56 volt battery. The current out of the battery is 10 amps. What is the power dissipated by resistor, R2, in Watts?

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
