Physics - December

<p>So how did all of you guyz do??</p>

<p>atrociously. j/k it wasnt that bad. way easier than when I took it before...</p>

<p>I thought it was significantly harder than any of the practice tests I've taken. Inlcuding the blue book... It seemed to have a way of overemphasizing the areas I underemphasized in my prep. : /</p>

<p>lol...laughs i left 11 blank but i didnt know any e/m</p>

<p>Hey I skipped 20 ish :( But I felt pretty comfy with the ones I did answer.</p>

<p>did no one take physics? lol...no discussions</p>

<p>physics was................... depressing. much harder than last time i took it. there were just some questions that i was like "WHAT?!?!?!" i had never even heard of some of those things they talked about. suprisingly though, it seemed there was very little kinematics, force vectors, tension, etc....</p>

<p>I agree completely with AJMCollegeIn07. I think most people are much more comfortable with kinematics than they are with obscure wave, nuclear physics, and thermal (which there was a ton of this test) questions. I left 3 blank, and I usually never leave anything blank. I think it was fairly tough to finish the whole test within one hour in ease.</p>

<p>blah123, if we start talking about the questions, then I'm sure others will start asking.</p>

<p>So for part I, what did the graph of the conducting sphere electric field charge vs distance from center look like? I put something that looked like 1/x. The other two graphs I put for that one were straight lines with slope about 1 from the origin.</p>

<p>Also, do you think the curve will be generous (I'm asking people who have previously taken the Physics test, or think they have a good idea what the curve will be)? There were definitely some weird questions (for me at least), like the tube question with the different intensities and frequencies...and the capacitor question, I put the answer choice with no change in charge</p>

<p>way too much e/m. i left 7 blank. that's pretty bad considering that i only left 2-3 blank on the practice tests.</p>

<p>nightflarer: i put the same as u for the first 2 graphs...i dont remember wat i put for the third one</p>

<p>how do u guys skip only 2/3 lol...my e/m is very limited since we had NONE of it in school and i had to learn it in like 2 weeks. did u guys take physics ap before this?</p>

<p>I left 8 blank. I guessed on a lot. Princeton gives like a 15 point curve on the practices. It could go any way. Can't wait for those scores, ahhhhhh.</p>

<p>Hey anyone know the answer for .. I think it was #70
that question with electromagnetic radiation</p>

<p>electron with constant velocity
electron with constant acceleration
capacitor discharging
.. I forgot the other two???</p>

<p>ugh I HATED that question, and the other one was an antenna with alternating something, cant remember the other. I have no idea what it was though...</p>

<p>what about the one with ABCDE, all pointing in different directions with an equal intial velocity. i think the question asked for the one with the greatest velocity upon impact.</p>

<p>oh yeah and the one with the 2 phase diagrams for 2 different substances? was it A, A, then E (impossible to know without knowing the mass).</p>

<p>I put C since it's initial y velocity was 0. for the phase diagrams with 2 different substances, I put A, A, then B I think. Didn't the problem say that both masses were the same? Oh crap, it didn't. Yeah, you're right then.</p>

<p>^ for the phase one was x on top or on bottom?</p>

<p>it did say it was the same mass i think?</p>

<p>yay i think i got C too.</p>

<p>no... im pretty sure they didnt give any information on the mass of the 2 substances...</p>

<p>ETA- anyone know the answer to the electromagnetic radiation q?????</p>

<p>^ do you remember the questions for the phase changes</p>
