You are working at a company that manufactures electrical wire. gold is the most ductile of all metals: it can be stretched into incredibly long, thin wires. the company has developed a new technique that will stretch 1.60 g of gold into a wire of length l = 2.20 km and uniform diameter. your supervisor gives you the task of determining the resistance of such a wire (in mω) at 20.0°c. (the density of gold is 19.3 ✕ 103 kg/m3.)
