As part of a class project you are given 0.900 g of copper and asked to fabricate a wire with uniform cross-section. You use up 95% of thecopper and make a wire with a resistance of 0.723 ? The resistivity of copper is 1.72 As part of a class project you are given 0.90 10-8 ? ? m and its density is 8.92 As part of a class project you are given 0.90 103 kg/m3.

(a) What length of wire do you end up with?
(b) What is the diameter of the wire?
