A student in Denver (altitude = 1 mile = 1609 m above sea level) brings a physics book of mass 1.3 kg to the top of a ten story building of height 26 m and holds the book over her head 151 cm above the roof.

At the north magnetic pole the earth's magnetic field is vertical and has a strength of 0.62 gauss. The earth's field at the surface and further out is approximately that of a central dipole.

A vessel of 0.25 m3 capacity is filled with saturated steam at 1500 kPa. If the vessel is cooled until 25% of the steam has condensed, how much heat is transferred, and what is the final pressure?

Which best describes Savanna's error? The label at the top of the diagram should be "FM Radio," not "Cell Phone." The FM carrier waves should have different frequencies than the carrier waves, not different amplitudes.
