ANSWER:

Problem 3.4.1

When you calculate the number of permutations of n distinct objects taken r at a time, what are you counting? Give an example.

Step by Step Solution

Step 1 of 2

When the number of permutations of n distinct objects taken r at a time is calculated, it technically describes the number of possible ways in which r distinct objects out of n distinct objects can be arranged. Since permutation deals with a number of different arrangements, order plays an important role in permutation.

Problem 35P According to the Sackur-Tetrode equation, the entropy of a monatomic ideal gas can become negative when its temperature (and hence its energy) is sufficiently low. Of course this is absurd, so the Sackur-Tetrode equation must be invalid at very low temperatures. Suppose you start with a s
