TIPS ON SUBMITTING HW ASSIGNMENTS WITH WEBASSIGN Please, never use your browser's BACK button in the middle of an WebAssign session. The system is designed to only move in the forward direction. The way things are set up at this time, you will have five opportunities to answer each part of each problem. To have your answer graded for a single part of a problem, fill in only that part and select "Submit New Answers to Question ____". If a part has been left blank, no submission is charged for that part. Always use three significant figures in your numerical answers (unless the program gives other instructions for a particular problem). Numerical answers must be correct to within 2%. To enter a number in scientific notation, use the format *.**E**; for example 5.97 X 10^24 would be entered as 5.97E24.
