1.- (5 points) We need to make three wires (gold, copper, and Aluminum). Wires must have a resistance of 1 ohm and a diameter of 1mm. what should the length of each wire be? What will be the mass of the gold wire be? Useful data: Resistivity for aluminum, Pal = 2.75 x 108 0-m. Resistivity for copper, Pe = 1.72 x 10-8 4-m. Resistivity for gold P. = 2.44 x 10-8 0-m. Density of gold equals 1.93 x 104 kg/m
