Cross out anything you don’t want us to read! • Make explanations correct but brief. Don’t write a lot of prose. • Include diagrams! • Show what goes into a calculation, not just the final number, e.g.: a · b c · d = (8 × 10 3 )(5 × 10 6 ) (2 × 10 5 )(4 × 10 4 ) = 5 × 10 4 • Give standard SI units with your results. Unless specifically asked to derive a result, you may start from the formulas given on the formula sheet, including equations corresponding to the fundamental concepts. If a formula you need is not given, you must derive it. If you cannot do some portion of a problem, invent a symbol for the quantity you can’t calculate (explain that you are doing this), and use it to do the rest of the problem.
