Whale and Kanmuro are two islands located at the Chimera archipelago. These two are separated by a distance of 16 miles. A power link is to be established between them. The power link delivers a maximum power of 584 megawatts at full capacity with an operating voltage of 580 kilovolts. Note that 1 mile is 1.6 kilometers. Solve for the resistivity (in ohm-micrometers) of the cable asusming a conductor diameter of 1.55 centimeters.
