The heating element in a hair dryer is essentially a wire whose resistance causes it to become red-hot when a current exisits in it. Such wires are usually made of nichrome (a nickel-chromium alloy), whose resistivity is p=1.0*10^-6 ohm*m. (a) Suppose one such wire has a diameter of 0.30 mm and a resistance of 9.0 ohm. What is the length of the wire? (Note that wires like this in a hair dyrer tend to be coiled around to save space)...

Now let's consider the resistance of speaker wire. Suppose you're hooking up a pair of stereo speakers, You happen to have on hand some 20-m-Jong pieces 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? To improve the performance of the system, you purchase...
