    After the due date solutions to your WebAssign problems can be viewed on your WebAssign page by clicking "Past Assignments", "Answer Key + Solution or Explanation".


    Give your answers with 3 significant figures in the units indicated.
    Powers of 10 should be in E format with no spaces. Example 3.14E9

    HW1: #5 (Chap 2, P 037):
    Hint: Make a graph of v versus t.
    HW3: #8 (Chap 4, P 068):
    Try to construct free-body diagrams but don't submit them.
    HW10: #6 (Chap 14, P 055): Note: windpipes are open-open tubes because we breath through them (until someone proves me wrong). However, just treat this problem as an open-closed tube as described in the text.
    HW10: #13 (Chap 15, P 046): The sphere is conducting.



    The exam will cover materials from the text, lectures, workshops and Homework problems.The exam will cover all materials from lectures and from the textbook as indicated in the Syllabus.
    There will be thirty multiple choice questions on the exam. The exam will be closed-book.
    You may bring two 8.5 x 11" sheet (double-sided) of notes in your own handwriting (no xerox copies). You will need to bring a calculator (a simple scientific one is best), your student ID card, and several #2 pencils to the exam. You will be asked to leave your backpacks with your cell phone at the front or rear of the room during the exam. Use of cell phones is strictly prohibited during the exam. Anyone with a cell phone out will have their exam confiscated.
    At the end of the exam carefully separate your exam cover sheet from the rest of the exam. Then turn in your signed exam cover page (with the answers) and show your Student ID to one of the proctors.

    CALCULATOR (again).
    If you have a graphing calculator, you may bring it to the exams. However, the best type to have for the exams would be a non-graphing scientific calculator. That will have all of the functionality that you will need.
    CELL PHONES (again).
    You should not have a cell phone on you during the exam. Please keep your (turned off) cell phone in your backpack or coat and leave your backpack and coat near the wall of the exam room away from any seat.
    At your seat you should keep calculator, pencils, a personal note-sheet and RU-ID.
