What is an "equilibrium temperature"?

A 5000-km long cable consists of seven copper wires, each of diameter 0.85 mm, bundled together and surrounded by an insulating sheath. Calculate the resistance of the cable. Use 3x10^-6 cm.Ω for the resistivity of the copper.

1. Many people make the mistake of believing that when a larger defensive player collides with a wide receiver who is making a catch in the air, the larger defender must be exerting a bigger force on the smaller receiver, leading to a greater chance
