Homework

Part of the weekly homework assignment is to done in Webassign (best to go there via the Blackboard link) and part will be done on paper and handed in. The paper HW problem is also found in WebAssign. For convenience all WebAssign HW assignments are also listed below.

Both are due on Fridays at 5 pm. The paper homework can be dropped off in the Lab Room (PHYS 154) or put into the Physics Department mail slot, outside of Room 144.

Please note that WebAssign has some particular requirements on how answers are entered. If it is not accepting your answer check out: Answers that cannot be understood. Please follow the instructions for the problems that are given in the WebAssign environment. The links below are to public forms of the problems and may not include specialized WebAssign instructions.

You will be asked to do 4-5 challenging problems including estimations, explanations, essay questions, worked out problems, and even some challenging multiple choice questions. You are encouraged to work on these with friends. We suggest using the Help Center for PHYS 234, which is conveniently located in the Lab Room (PHYS 154). (Schedule to be posted elsewhere.)

You have to write up your solutions independently. Be careful: If two or more submitted answers are essentially identical, neither will receive credit. The quality of the presentation will be considered in the score as well as the quality of the solution.

It is primarily your responsibility to figure out what you might have done wrong when you get your graded paper HW problems back. If you need help, however, just bring it to the Help Center and discuss it with a TA.
