a. Tidal heating can lead to subsurface zones of liquid water.
b. Tidal heating causes surface oceans to slosh back and forth with the tides.
c. Tidal heating is thought to be necessary for life on any world.
d. Tidal heating can melt surface ices into liquid lakes and seas.

A top is set spinning so that the rotation is counterclockwise around its axis when viewed from above. When the top is placed on a level surface it happens that its axis of rotation is not quite vertical. Viewed from above, which way does the rotational axis of the top precess?
a. clockwise b. counterclockwise c. It's random, if it starts clockwise it will continue clockwise, and vice versa, i.e., a 50% chance either way. d. The direction depends on the little shove given to the axis when the top is placed on the surface. e. In the northern hemisphere it will be clockwise, in the southern hemisphere it will be counterclockwise.
An 800-kHz radio signal is detected at a point 8.5 km distant from a transmitter tower. The electric field amplitude of the signal at that point is 0.90 V/m
Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. What is the average electromagnetic energy density at that point? (c = 3.0 × 108 m/s, ?0 = 4? × 10-7 T ? m/A, ?0 = 8.85 × 10-12 C2/N ? m2) A) 3.6 pJ/m3 B) 5.1 pJ/m3 C) 7.2 pJ/m3 D) 10 pJ/m3 E) 14 pJ/m3
Figure 2-70 shows a section of a large surface plate used for precision measurements. A person touches the surface and thereby induces heat transfer through the plate. Neglecting radiation involved, write the node equations for nodes 1, 5, and 12.
How large is Jupiter's magnetosphere?
A) It is about as large as the Earth's. B) It is so large it extends out to the orbit of Io. C) It is a million times the volume of the Earth's, extending beyond the orbit of Saturn. D) It extends inward to the orbit of Mars. E) It envelopes even the Sun and rest of the solar system.
