A 0.60-mm-diameter wire made from an alloy (a combination
Chapter 27, Problem 27.95(choose chapter or problem)
A 0.60-mm-diameter wire made from an alloy (a combination of different metals) has a conductivity that decreases linearly with distance from the center of the wire: s1r2 = s0 - cr, with s0 = 5.0 * 107 -1m-1 and c = 1.2 * 1011 -1m-2 . What is the resistance of a 4.0 m length of this wire?
