Answer 1

Answer:

Estimate the average drift speed of conductin electrons in a copper wire of cross sectional area 1.0×10-7m2 carrying a current of 1.5 A. Assume that each copper atom contributes roughly one conduction electron. The density of copper is 9.0×103kgm-3 and its atomic mass is 63.5u. ... speed vd is given by vd=(I/neA).
