Calculate the resistance of a 5.46m length of lead strip, 0.450cm wide and 1.25mm thick. What length of similar strip, but made of copper, would have to be put in parallel with the lead strip for the effective resistance of the combination to be 0.100 ohm? (Resistivity of lead = 20.6 × 10E-8 Ohms meter; of copper = 1.72 × 10E-8 Ohms meter)

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
