Chapter 32, Problem 47P
SSM ILW WWW The magnitude of the magnetic dipole moment of Earth is 8.0 × 1022 J/T. (a) If the origin of this magnetism were a magnetized iron sphere at the center of Earth, what would he its radius? (b) What fraction of the volume of Earth would such a sphere occupy? Assume complete alignment of the dipoles. The density of Earth’s inner core is 14 g/cm3. The magnetic dipole moment of an iron atom is 2.1 × 10–23 J/T. (Note: Earth’s inner core is in fact thought to he in both liquid and solid forms and partly iron, but a permanent magnet as the source of Earth s magnetism has been ruled out by several considerations. For one, the temperature is certainly above the Curie point.)

- You are working with a team that is designing a new roller coaster-type amusement park ride for a major theme park. You are present for the testing of the ride, in which an empty 150 kg car is sent along the entire ride. Near the end of the ride, the car is at near rest at the top of a 100 m tall track. It then enters a final section, rolling down an undulating hill to ground level. The total length of track for this final section from the top to the ground is 250 m. For the first 230 m, a constant friction force of 370 N acts from computer-controlled brakes. For the last 20 m, which is horizontal at ground level, the computer increases the friction force to a value required for the speed to be reduced to zero just as the car arrives at the point on the track at which the passengers exit. (a) Determine the required constant friction force (in N) for the last 20 m for the empty test car.
