Copper has fcc structure. If its density is 8.92 g cm^-3 , calculate its radius if atomic weight of Cu is 63.5 g mol^-1 .

The mass of a coil of copper wire of diameter 1.2 mm is 150 g. If the density of copper is 8.9g*cm^(-3) , then find the length of the copper wire.

(a) Estimate the average drift speed of conductin electrons in a copper wire of cross sectional area 1.0xx10^(-7) m^2 carrying a current of 1.5 A. Assume that each copper atom contributes roughly one conduction electron. The density of copper is 9.0xx10^3 kgm^(-3) and its atomic mass is 63.5 u. (b) Compare the drift speed obtained with the speed of propagation of electric field along the conductor, which causes the drift motion.
