In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.100 Ω and no change in resistance with temperature. She suggests making the resistor from lengths of cylindrical carbon and Nichrome wires of equal radius, placed end-toend. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.50 mm. What are the lengths of the two segments of the resistor?
