    PHYSICS SAT2 are calc allowed?!?

    Calculators are not allowed during the Physics SAT2 and they do not give you constants (at least they didn't on the one I took) so I would recomend memorizing them. Hope this helped and good luck on your Physics SAT2!!! :-]

    Physics problem(sound waves)?

    Here is how you solve for x: 470 = [1 / (1 - x / 346)]450 470 = [1(346 / 1-x)]450 470 = [346 / 1 - x]450 470 = 155,700 / 1 - x 470 - 470x = 155,700 -470x = 155,230 x = -330.27659574 x = -330.3 Hope this helped :-]
