The dense, rocky, and metallic planets are found close to the Sun because:

a. the Sun’s gravity attracted the denser particles (rocks and metals) closer to it.
b. the Sun was unable to hold onto the lighter (gaseous) particles and they moved farther away where they formed the outer planets.
c. rocks and metals condensed at the relatively high temperatures close to the Sun.
d. they were nudged inward by close encounters with Jupiter early in the solar system’s history.


Answer: c. rocks and metals condensed at the relatively high temperatures close to the Sun.

Consider an object (object A) whose multiplicity is always 1, no matter how much energy you put into it. If you put a very large amount of energy into such an object, and place it into thermal contact with an Einstein solid (object B) having the same number of atoms but much less energy, what will happen?

A. Energy flows from A to B until A has very little energy. B. Energy flows from B to A until B has very little energy. C. Energy flows from A to B until both objects have the same energy. D. No energy will flow between A and B at all. E. Something else happens (describe).

Two eggs of equal mass are thrown at a blanket with equal velocity. Egg B hits the blanket but egg A hits the wall instead. Compare the work done on the eggs in reducing their velocities to zero

a. More work was done on A than on B. b. More work was done on B than on A. c. The amount of work is the same for both. d. It is meaningless to compare the amount of work because the forces were so different. e. Work was done on B, but no work was done on A because the wall did not move.
