8/05 You should skip part (d) in Wolfson 34: 71 in
tonight's HW. We did not cover EM wave momentum.
8/03 Problem H36: 17 was originally left off the online
problem list for July 30 - Aug 5. It has now been
added.
7/30 There is a misprint in the HW list for Mon Aug 2.
H 31:11,12 should be H 33:11,12.
7/30 The solutions for test 3 are now available
at the Noble Library Copy Center.
7/25 The solutions for test 2 are now available
at the Noble Library Copy Center.
7/17 The solutions for test 1 are now available
at the Noble Library Copy Center.
7/16 The answer originally given for H27:43(a) uses
Halliday's value for kappa of Pyrex (4.7). Using
Wolfson's value of kappa for Pyrex (5.6) yeilds a
capacitance of 863 pF.
7/15 The answer to Wolfson Chapter 25 problem 58(a) was
originally posted incorrectly. The correction was
made at 1 PM TH 7/15. The correct answer is 288 kV.
7/14 Comment on HW problem H26:20 -- Use of "k" in the
original statement of this problem results in
confusion with the electrostatic value of k. So I
have changed that "k" to a "c", and the answers on
the even-numbered answers page are given in terms
of that "c".
7/09 In the HW for July 12, please drop problem 26:5
and add problem 26:3. Also, I STILL did not give
complete info for problem P24:55. In order to get
the numerical answers you need to know the value of
y at the top and bottom of the cube. y = 0 at the
bottom, and thus y = 2 m at the top of the cube.
This is a valuable exercise in the use of Gauss' Law,
so - in spite of my awkward presentation - I hope
that everyone will work through it completely.
7/08 In problem P24:55, the figure reference was
originally wrong. It was corrected at
10:00 AM Thur Jul 08.
7/07 The Old Tests, with solutions, are now
available in the Noble Library Copy Center.
7/06 Problem P 23:25 was initially left off of
the Online Problems list for July 6 - 12.
It was added July 6 at 2:00 PM.
