The answers provided here are for selected end-of-chapter problems. For “True/False” or “Yes/No” questions where “Why” is also asked, only selected answers are included in this appendix; the explanation of “why” is not provided. Instead, a reference to the location of the explanation is given. For problems that have numerical calculations, the final answer is given so that the result can be checked. The solutions to some of those selected problems are explained in plain English as opposed to providing the numerical calculation(s).
