(a) An aluminum power transmission line has a resistance of 0.0580Ω/km0 . \text{0580} \Omega / \text{km}. What is its mass per kilometer? (b) What is the mass per kilometer of a copper line having the same resistance? A lower resistance would shorten the heating time. Discuss the practical limits to speeding the heating by lowering the resistance.
