PHY 2060

Homework — Spring 2007

Although the homework is graded, it is intended more as a learning tool than a means of assessment. Collaboration among students is permitted.

The homework will be assigned, submitted, and graded online through the CAPA Web system. Information on CAPA access, availability, and use are provided further down this page. Students are responsible for reading this page carefully and following all instructions presented here. If you don't understand anything, please contact an instructor.

CAPA Access

To access a CAPA homework set, you need to follow the link above to the CAPA login page, where you must supply three pieces of information:

• The class. Select "phy2060" from the pull-down menu.
• Your Student PIN: a nine-digit number consisting of the last four digits of your UF ID number followed by a zero followed by the four-digit PIN that you have selected.
  Example: Albert Einstein's UF ID number is 1879-1955 and he has chosen a four-digit PIN of 1905. His Student PIN is therefore 195501905.
  Note: Do not follow the link "Click here to register get a Student PIN".
• Your CAPA ID: a four-digit number that changes for each homework set. To look up your CAPA ID, go to the CAPA login page and follow the link "Click here to get your CAPA ID". You will be prompted to enter your UF ID (with no hyphen in the middle), your Student PIN, the course, and the number of the homework set.

You need to remember the four-digit PIN you have selected. If you forget your PIN, you will have to see an instructor in person to have it looked up. (No PIN will be divulged by email or telephone.)

Do not share your PIN with anyone other than Profs. Ingersent and Tanner. If you believe that your PIN has been compromised, you should see one of the course instructors to have it changed.

Close your browser after completing a CAPA session to make sure you are logged off. (The CAPA "Exit" buttons do not seem to work.)

If you experience problems using the CAPA system, please contact an instructor.

CAPA Availability

Each CAPA homework set is available for you to attempt only during an open window: normally, 12:30 p.m. on Tuesday through 7 p.m. the following Monday or Tuesday. You will receive a score of zero on any problem that you don't attempt during the open window (or that you attempt but fail to get correct). Don't wait until the last minute to do the homework! Extensions will be granted only if there is a campus-wide network outage or a problem in the Physics Department that prevents access to the CAPA system.

CAPA Use

• The answers to most CAPA problems are numerical.
• Many problems involve very large or very small numbers, so you will need a calculator capable of using scientific notation.
• A number such as 1.5×10^-15 should be entered into CAPA as "1.5e-15" or "1.5E-15".
• CAPA allows you up to 10 attempts at each problem, and tells you when you give a correct answer.
• You receive one point for each CAPA problem that you get correct.
• After you have filled in the answer to one or more problems, you can click "Submit All Answers". This will only count as one of your 10 allowed tries for those problems for which your answer is non-blank and different than the last answer. This allows you to work through the homework one problem at a time, waiting until you get the right answer to one problem before moving on to the next.
• You can quit CAPA whenever you like, and login again to the same homework set any time within its open window. The system will remember your previous problem attempts and you will restart your session where you last left off.
• The CAPA "Exit" buttons do not seem to work. Close your browser when you have finished with CAPA.
