    Calculate the drift velocity of electrons in a copper wire given the current flowing in it, its diameter and density.

    A copper wire 2.5 millimeters in diameter is carrying a current of 10 amperes. Assume one free electron per copper atom and find the magnitude of the drift velocity. [Copper has a density of 8.92 grams/(centimeter)^3, an atomic weight of 63.5 grams/mole, and Avogadro's number is 6.0 x 10^23/mole.
