2. in the electric current flow, it is found that the resistance (measured in the units called ohms) offered by a fixed length of wire of a given material varies inversely as the square of the diameter of the wire. a) set up a formula using k as the constant of proportionality. b) if a wire 0.01 inches in diameter has a resistance of 0.381 ohm, find k. c) what is the resistance of a wire of the same length and material with diameter 0.0298 inches. (round to the nearest ten-thousandth)
