A carbon wire and a Nichrome wire are connected one after the other. If the combination has total resistance of 10.0 k ohm at 20°C, what is the resistance of each wire at 20°C so that the resistance of the combination does not change with temperature?(resistivity at 20°C of: nichrome= 1.5x10^-6 ohms m, Carbon= 3.5x 10^-8 ohms m, Temp. coef of resistivity: nichrome= .4x 10^-3/°C, carbon:-.5x10^-3/°C)
