In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.130 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-to-end. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.32 mm. What are the lengths of the Nichrome segment and the carbon segment of the resistor (in m)?
