A length of #8 copper wire (radius = 1.63 mm) has a mass of 24.0 kg and a resistance of 2.061 ohm per km (ohm/km). What is the overall resistance of the wire? (Hint: Begin by using the mass and the density of copper to determine the volume of the wire and then use V = p(r^2)l to determine the length of the wire.)
