Suppose you are hooking up a pair of stereo speakers (A) You happen to have on some 20 m long peices of 16 gauge copper wire (diameter 1.3 mm); you use them to connect the speakers to the amplifier. These wires are longer than needed, but you just coil up the excess length instead of cutting them. What is the resistance of one of these wires? (B) To improve the performance of the system, you purchase 3.0 m long speaker cables that are made with 8 gauge copper wire (diameter 3.3 mm). What is the resistance of one of these cables?

You have a lump of copper with a mass of 1.8 grams. Copper is ductile so you can draw it into a cylindrical wire. You draw it into a wire with length L and diameter D so that it has a resistance of 2Ω. What is the length of the wire in m and the diameter in mm? Hint: you may need to look up some properties of copper!
