For some an application, it is important that the value of a resistance not change with temperature. We want to make a 4.70-kO resistor from a carbon and Nichrome wire-wound resistor conected together so the total resistance is the some of their separate resistances. What value of should each of these resistors have ( at 0 °C) so that the combination is temperature independent?

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.
