REMARKS ABOUT HOMEWORK WEBASSIGN:
Give your answers with 3 significant figures in the units indicated. This avoids difficulties with webassign's 1% precision rule.
Powers of 10 should be in E format with no spaces. Example 3.14E9
HW#4, problem 4, (5:78)
In part b) the power output refers to the effective power delivered,
not the total energy per time that the body must produce and of which
80% is lost internally.
HW#6, problem 8, (9:58)
Since P1 is larger than P2, the larger radius is r1 and the smaller
radius is r2.
HW#12, problem 2, (16:09)
part c). Note that the maximum extension of the spring is at x = 2A,
and that at that
position the electric potential is lower than at x = 0.
HW#13, problem 5, (29:10)
See Appendix B, pages A.14-A.18
HW#13, problem 9, (29:10)
For half life see Appendix B, pages A.14-A.18
HW#15, problem 5, (25:28)
Follow the hint: Go back to basics, meaning:
Find the heights of final image, intermediate image and object.
