<p>So we have 63 questions. Just 12 more! c’mon keep posting the question, even the easiest ones!:P</p>
<p>^^Ohh alritey, then that is correct 
^Wow really?!</p>
<p>There was also one where u were asked how many electrons flow per second in a wire with current 1,6 A. They gave u the fact that:
1e= 1,6<em>10^-19 C. That means that: 1C = 6,2</em>10^18e.
Since 1,6 A is 1,6 C per second, u had to multiply 1,6<em>6,2</em>10^18 = 1*10^19 electrons, which was the final answer.</p>
<p>Speaking of wires, there was also one question on a current carrying wire, and they asked u about at what angle would the magnetic or electric (cant remember) would be maximized. I didnt know if it was 0, 45 or 90 degrees. Any ideas?</p>
<p>^65, with these 2 :D</p>
<p>There was also one where they asked u about a scenario that described convection. The answer had to deal with a fan, but cant remember it clearly.</p>
<p>66 questions!</p>
<p>The question about what angle made the magnetic force stronger was 90 degrees, I think. I remember seeing a formula for that that ended in sin(theta). 90 degrees would maximize that value.</p>
<p>I’m crossing my fingers for a good curve. I’m at about -10 to -12 right now for my raw score.</p>
<p>^^The current one: maximized at 90 degrees i believe, since sin 90 =1 and anything lower is <1. The formula is Mag Force = ILBsin(theta) where I is current, L is length, and B is mag field</p>
<p>and i agree with the electron one</p>
<p>^ I dont remember the convection one lol</p>
<p>Ok thank u :D. What about the convection question?</p>
<p>@PioneerJones: Same here! I’m hoping around a -12 or -13 is an 800, which would seem plausible considering that -16 was an 800 on the BB test, so this is probably a few points lower, and since it was fairly challenging, -12 or -13 =800 sounds pretty good :)</p>
<p>Also, can someone update the compiled questions list</p>
<p>Does anyone remember what the question and answer was for the question of the light ball and heavier ball was? I just remember that, but dont know anymore what it asked. And do u remember what the choices were? :P</p>
<p>I don’t believe we answered the first question. The one that asked where the electrical potential was stronger at Y than X, and it was the first two because Y was closer to the center charge than X.</p>
<p>I’m also having a mild panic over math II. I’m at -5 as far as I know. If I missed another question, I’m out of 800 range.</p>
<p>^^The light and heavy ball one was that after 1 sec, the heavy ball had fallen further. I put that the this was due to the greater gravitational force being on the heavier ball</p>
<p>^Don’t worry PioneerJones, your scores are gonna be amazing anyways!</p>
<p>Also guys, i started a curve prediction thread if you guys wanna check it out</p>
<p>I can’t imagine my schools would be so particular as to deny me for a 780 or 790 :P</p>
<p>Anyway, I left the large ball/small ball one blank, but we agreed that the right answer was the ratio of volume to surface area answer. Acceleration due to gravity is the same for all objects, so ^your answer would be incorrect.</p>
<p>I think both answers are incorrect. Volume to surface area ratio has not much to do with it. I thought it was something related to air resistance??? I just cant remember what the choices were, though, so if u can help me i will appreciate it so much. 8P</p>
<p>There were questions with parallel plates, but all I only remember a question asking when something was zero.</p>
<p>I thought that too, but the only answer involving air resistance said that the air resistance was stronger on the ball that fell further, which was backwards. I was tempted to choose that answer, but the phrasing made it seem like it was wrong.</p>
<p>omg i just remembered another one. About 3 particles. A proton was in the middle of the other two and were in equilibrium. However, when u removed one particle of the sides the proton was attracted to the other one, so the answer was that both side particles were negatively charged (electrons).
68 questions</p>
<p>That reminds me of another one. There were two charges if +4 and +1 and it asked where you should put a negative charge so that it would experience a net force of 0. It had to be between them, but closer to the 1 charge.</p>
<p>69!</p>
<p>OMG i just cant remember that question AT ALL! hahaha</p>
<p>I remember that question in the blue book, I don’t think it was on the test. lol</p>
<p>You’re right, it was in my Kaplan book. I took two practice tests the day before, and they’re all starting to blend together :P</p>
