Here you can ask Dr. Carter questions during the lecture.
Attached are the solutions for Midterms 1 and 2.
Homework 5 - 12 questions
From Chapter 8: Waves (regular textbook)
1, 2, 3, 6
From Extra Chapter 13: Quantum Physics (mainly sections 1 & 2)
http://www.lightandmatter.com/html_books/0sn/ch13/ch13.html
1, 2, 11, 13, 14, 17, 18
NOTE: Chapter 13, problem 8 has been removed from the assignment
For problem 11c, you can use the values N(t) = 3.11 x 10^21 and N(0) = 3.15 x 10^21
EDIT: The correct value for N(0) is actually 3.17 x 10^21 (if you've already done the problem with the first value I gave, don't worry about it!)
Due Thursday, 3/10
Homework 4 - 11 problems
Note: The problem titled "Extra Problem" is REQUIRED. It is NOT extra credit!
Attached is the homework assignment and a chapter on Optics and Refraction (needed to do the second part of the homework).
Attached is a powerpoint covering topics in electricity given on Tuesday, February 8. This should help with Homework 3!
Homework 3 - 10 problems
Supplemental Information for Homework 3
(click on actual blog entry for full list!)
Also see the attached powerpoint for more help.
Energy given by a potential (voltage) difference:
Energy = q*V (q is charge, V is the potential difference)
Electric field:
E = -dV/dx
(dV is the change in potential, dx is the distance over which the change occurs)
Energy from a capacitor:
U = 0.5 * C * V^2
(U is energy (Joules), C is capacitance, V is the potential/voltage)
Capacitance for a parallel-plate capacitor:
Homework 2 (13 problems)
From Crowell's Conceptual Physics
Chapter 2: #9, 11
Chapter 3: #1, 2, 7
Chapter 4: #4, 6, 7
Also do the attached "Additional Problems" A-E.
Due Tuesday, 1/25
Since there is no school Monday 1/17, Alice's office hours next week will be on WEDNESDAY 1/19 from 2 - 3 pm (ISB 262).
You can ask Professor Carter questions here during lecture.
Homework 1
Chapter 1 in Crowell's Conceptual Physics (online textbook)
#2, 7, 8, 11, 13, 16, 17
Due Tuesday, 1/11
SUPPLEMENTAL INFORMATION FOR HW 1: (Note: You do not need to use all of this to do the homework - I simply included equations I found helpful to know when going through the homework).
Power = Energy/Time
Power is in Watts. 1 Watt = 1 Joule/second
1 kJ = 1000 Joules
weight = mass x g (where g is the acceleration due to gravity on the Earth's surface, 9.8 m/s^2)
Force = mass x acceleration (F = ma)
General physics questions can be asked here in the comments, and either Professor Carter or Alice will respond.
