An 80 cm long wire is made by welding a 1.8 mm diameter, 20 cm long copper wire to a 1.8 mm diameter, 60 cm long iron wire at normal room temperature (20 ∘C). When two wires are connected end to end, their resistances add together. The resistivity of copper is 1.68×10−8Ωm and the of iron is 1.00×10−7Ωm. The temperature coefficients are: copper = 0.0039/∘C and iron = 0.0050/∘C. What is the resistance of the iron section of wire?
