A 20.0m -long cable consists of a solid-inner, cylindrical, nickel core 11.0cm in diameter surrounded by a solid-outer cylindrical shell of copper 11.0cm in inside diameter and 22.0cm in outside diameter. The resistivity of nickel is 7.810^-8 ohmm. What is the resistance of this cable? If we think of this cable as a single material, what is its equivalent resistivity?
