	Errors in Unit C, 2/e

NOTE: In all that follows I will use <letter name> to represent a Greek-letter variable, ^ to indicate that the next quantity is superscripted, _ to indicate that the next quantity is subscripted, and boldface to indicate a vector quantity. I will also go against typographical convention and put punctuation outside of quotation marks to make whatever is enclosed in quotes exactly reflect what is (or should be) in the text. The date at the end of each item refer to the date that the error was first posted.

Inside front cover, useful conversion factors: dot should be centered in "1 kW.h = 3.6 MJ" (9/11/02)
page xii, in the list of volume titles: the title of unit E should be "Electric and Magnetic Fields are Unified", and the title of unit Q should be "Particles Behave Like Waves". (9/11/02)

page 49, first paragraph, lines 4 and 7: references to 5/3 should be replaced by 4/3. (9/11/02)
page 53, fourth line on the page: replace "as a being" with "as being". (5/29/03)
page 58, problem C3T.4: delete "and come to rest" at the end of the first sentence. (9/13/03)

page 172, problem C9A.2, 4th line from the end: m_j = Mr_j<delta><theta>/2R_j, not m_j = Mr_j^2<delta><theta>/2R_j^2 (the r_j and R should not be squared). (9/11/02)
page 181, fourth line above equation C10.5: insert a U in front of the comma in "distinguishes both from internal energy,". (08/13/04)
page 184, equation C10.8: use a capital M instead of a small m for consistency with equation C10.7. (08/13/04)

page 201, example C11.6: the first numerical result for <delta>T can be misleading, because it does not take into account the change in temperature of the icewater. This is particularly a problem if students apply the same method (without thinking) when doing problem C11S.6. It is probably better to analyze each possible outcome fully, rather than try to take the shortcut I did. (08/13/04)

page 258, Conceptual Model Diagram, right side: change "r_f <approx. equal to> 0.5 m" to "r_f <approx. equal to> 1.5 m", and adjust the line connecting this r_f symbol so that it connects with the r_f above instead of the 2m. (8/17/05)
page 259, equations C14.14a, C14.15, and C14.16b: change "9.1" to "13.2", and similarly in (8/17/05)
page 259, equation C14.15: change the answer to "1.0 rev/s". (8/17/05)
page 259, equation C14.16b: change the answer to "4.0". (8/17/05)
