<p>As soon as we can start discussing, we should compile answers</p>
<p>i thought it was okay...but 4~5 questions i had no idea what the questions meant.</p>
<p>pretty easy I think</p>
<p>not too bad, but I never know, physics is the kind of test where you can get a bunch wrong and not even know it.</p>
<p>^ I KNOW!!!!!!!!!!! ughh last year every time i took a test i was like "yes! aced it" and then the next day I found out I missed like 8 out of 50. </p>
<p>But when I took it last year I thought I really didn't have enough time. I managed a 750</p>
<p>For those who took it today (or previously), what did you do to prepare (Kaplan/PR/Sparknotes, etc.), and did you feel adequately prepared for all of the questions on the test?</p>
<p>I prepared with PR. I thought it did a good job. However I didn't really study as much as I should have, really only thurs night and all of friday. I've had honors physics, AP Physics B, and im in AP Physics C so i've seen the stuff a lot, but its really that later stuff like magnetism and electricity that I forgot/didnt really know in the first place, that's what gave me trouble.</p>
<p>when can we start posting answers?</p>
<p>cannot remember any questions...anyone want to start?</p>
<p>whats the answer for the mummy question?? in which the half life of the isotope was given....</p>
<p>i had NOOOO idea... i just put 5*10^3, which i know is 99% wrong...</p>
<p>i think it was 5x10^-3</p>
<p>Ok for the question where the waves interfered i think it was #17, what happened, was the interference larger at point L or was it the same all throughout?</p>
<p>does the frequency increase when you increase tension?</p>
<p>This test was so hard I think the curve will be very generous maybe 60 for an 800</p>
<p>i calculated the phase difference for it and got 4 pie which obviously constructive interference....so i ticked the amplitude larges at point L.</p>
<p>freq is directly proportional to root of tension....so it increases</p>
<p>still not sure about the mummy one though....what was the logic behind it??</p>
<p>bohr model?</p>
<p>i dun remember the exact ques....can u write it here....</p>
<p>dexter87, what r u talkin about for the 4 pie one? can u explain it little bit more clear?</p>
<p>the 2 distances from the point and the wavelength were given right?? you can easily calculate the path difference by just subtracting the 2 distances...now path difference=(wavelength/2 pie)*phase difference...so u can calculate the phase fifference from here which comes out to be a multiple of 2 pie which like i said means constructive inteference....this is wht i did....not 100% sure about it though...</p>
<p>i mean, the problem itself... I don'r remember anything about there being a interference question....</p>
<p>It was something like... They gave you a graph with different metals W X Y Z and shone light on it. Didn't understand it so skipped it ;)</p>
<p>In the bohr model one I think I chose the answer "energy levels have the same distance between them". </p>
<p>Anyway, this is my third year taking physics but because I didn't review stuff on electricity and magnetism and some stuff like thermodynamics I haven't covered I don't think I did too well...</p>
<p>What's the curve on the Physics SAT II? Is it as generous as Math Level II? Or more like the SAT I?</p>
<p>WXYZ had to do with photoelectric effect</p>
