The resistance R of a wire varies directly with the length L of the wire and inversely with the square of its radius r. A wire with a length of 350 cm and a radius of 0.4 cm has a resistance of 16 ohms. Determine the resistance of a 500 cm piece of similar wire with a radius of 0.35 cm. Round your final answer to four decimal places and be sure to include units.

A length of metal wire has a radius of 0.002 m and a resistance of 0.1 ohms. When the potential difference across the wire is 13 V , the electron drift speed is found to be 0.000208 m/s. Based on these data, calculate the density of free electron in the wire. The fundamental charge is 1.6 x 10^-19 C i cant figure this out
