<p>u mean #1 and #2?</p>
<p>D and E were ruled out immediately. </p>
<p>I thought those two questions were pretty straightforward but I don't remember the answers to them...</p>
<p>Yeah, well more like #2
There seemed to be two sets of waves that were periodic and had different frequencies</p>
<p>the test definetly felt easier and i did get screwed over by time or I would definetly get 800..now its looking like 750...time screwed me over last time too</p>
<p>the first two question with waves... one of them was the one out of phase (cant rmeember, think B?) and the second one was the one that both were sine curves and started at (0,0) but one went just a wee bit faster (i think C?). </p>
<p>current conducting loop... what was that one? The oddly shaped pear-like one? The more pointy it is, the more charge is situated at that end so you're right.</p>
<p>Expanding universe has to, since there was no "I Only" ansewr, and doppler shift is definitely an answer, and the elliptical orbit one makes no sense at all.</p>
<p>Time was fine although I didnt get to check over as much as I would have liked...</p>
<p>the answer was definitely "ball is thrown 6 times as high." Mass doesn't change, and the math checks out on answer choice B.</p>
<p>does anyone remember the questions at the end of the test b/c i rushed through them so fast i dont even remember anything about them</p>
<p>also, witht he negetively charged particle, it went in circular motion down right??</p>
<p>yeap, it goes in a circular motion down</p>
<p>what about the question with the walls and the temperature outside as 5 C? I wasn't exactly sure how to do it.</p>
<p>now that one made me go grrrr... it probably has something to do with volume since they gave u thickness and surface area... but i think 4 of the ones (B, C, D, and E) had the same volumes. So i picked the one that had the lowest temperature. (forgot which)</p>
<p>I had no clue about that question, I think I put E. it was definitely for height = 9 (smaller area = smaller surface for heat loss), and the less the temperature difference, the less it'll lose to the environment. so thickness = .2 i think.</p>
<p>hmm... for the guitar string one... I thought it said that the ends had to have anti-nodes, so I selected (E). I guess that's just another oversight, and with it goes the chnace for an 800. :(</p>
<p>Oh and for the tension one, it was W. You never look at the pulley. Tension is what was pulling up on both masses, so it has to be W.</p>
<p>Also, once again, if anybody remembers the stuff from the capacitor question, please post it. Was it Potential or Force that the question asked for? and did anyone else get "not enough information" for the last question in that series?</p>
<p>ditto fahood on clarification for the capacitor one. i clearly, CLEARLY remember it asked for force, but had that been the case, force shoudl've been the same throughout the space between the capacitor? or do i have a huge conceptual error here..</p>
<p>the tension one was asking for the tension in the string holding up the pulley...</p>
<p>for the thickness of wall one..i found that kind of easy
the rooms temperature had to be close to the outside one so the lowest temperature which was 17 degrees C was the choice</p>
<p>for the surface area - it had tobe the least</p>
<p>for thickness - had to be the most</p>
<p>and i think the answer was E</p>
<p>for the capacitor is was all force is equal - im 100% sure it didnt ask for potential rather just force</p>
<p>Yes, force is the same because point charges are the same charge and it's in a uniform E field.</p>
<p>The capacitor question was not "not enough information." It's true that E can be calculated with E = F/q, but E is also calculated by E = V/d. They give you V (100v), they give you d (10cm). So E = 1000V, and F = Eq = 1000*2E-6 = 2E-3. Dont quote me on this, i can't remember the numbers exactly but you get the point.</p>
<p>hmm i see haha</p>
<p>welllll that brings me to 4 omit and 6 wrong. ahh</p>
<p>I'm at 7 wrong, 0 omit so far.</p>
<p>why is the magnetism/electricity so much harder than the mechanics on this test -_-</p>
<p>so im guessing the curve is around 7-8 qs = 800?</p>
<p>7-8? really? :( According to the practice tests in Kaplan it's -12 = 800, and same for the "real sat 2's" book from 2002...</p>
<p>i dont know im just guesstimating <_<</p>
