<p>well 740 isnt bad.. did you think this one was harder?</p>
<p>i really want 780+ what is the number i can miss if i omitted one?</p>
<p>did any q have interference as da ans? sumthin abt slitz n stuff</p>
<p>74 was D.</p>
<p>F = (Kq1*q2)/r^2 where r is the distance between the centers of mass of the two charges.</p>
<p>Icm = (1/m) ∫(m) dx</p>
<p>The center of mass comes out to be about where D is.</p>
<p>Even if you didn't know this you could eliminate A and B because they were about the same distance apart from the center.</p>
<p>For the light speed question I believe it was c, because it said observed, which means light, and the speed of light is constant irrelative to the velocity of the observer, that is, someone going 0.8c still observes the speed of light as c. I put greater than 0.6c but less than c.</p>
<p>For the expanding unverse question, I was, wow, amazed. I like quantum mechanics but I wasn't really happy about the questions. I put I & II, because there is no way that eliptical orbits prove the expansion of the universe (btw, the universe is accelerating), so it was down to two choices right off the bat.</p>
<p>That test was pretty hard.</p>
<p>did any q have interference as da ans? sumthin abt slitz n stuff</p>
<p>Yes, interference was the correct answer.</p>
<p>I hope I can pull off a 700+.</p>
<p>hp, how many u think u missed? you can miss like 20 and get 700+.... why dont u think u got 800 if u know stuff about quantum mechanics?</p>
<p>by the way, i knew that the expansion is accelerating too..... :) dont remember from where though..</p>
<p>I know a crapload about quantum phenomena (eg. quarks, mesons, gravitons, etc..) but I really make a lot of stupid mistakes. Forget a 2, etc...</p>
<p>Thus far, no confirmed wrongs, I omitted 2 (the galvanometer one, and 73), but there will be lots of wrongs.</p>
<p>I don't remember any nuclear reactions questons at all, and at the end I messed up my answer sheet, because I figured out I was one place off in my test book and the answer sheet. Luckily the problem was traced back to 73.</p>
<p>Man I want to kick the ETS into the balls.</p>
<p>i know how you feel.... i hate standardized tests.. i always make stupid mistakes because there are so many problems, you are bound to make a few dumb mistakes in 75 questions</p>
<p>My stupid mistakes gave me a 680 in math, even though I have a 98.2 average in AP Calc without ever doing any HW or stuff like that (HW is optional). Imagine how I feel.</p>
<p>LOL you sound exactly like me... except i got 720 math. i got a 100 for the year in both calc ab and calc bc... but I made 4 stupid mistakes to get me a 720 on sat I math haha</p>
<p>i have app princeton ED.. so even my 2nd score (770 btw) is pretty low... moreover, as an intl i guess the SAT IIs are more imp than SAT I (i got a 1460) other colleges on my list incl johns hopkins, cornell, MIT... i know im aiming realy really realllly high!</p>
<p>770 is not low.. think you'll get 800 this time? would you be mad if i got 800 the first time i took it?</p>
<p>oh there was another question:
find the point where the direction of the electric force or electric field.. is WEST</p>
<p>there were two charges, and the test charge was negative, i think the answer was D but im not sure if i read the question right
can anyone confirm this??</p>
<p>I picked A, the one on the far left</p>
<p>hmmm does anyone else remember this question??</p>
<p>bsblall...i wud be really happy if u get 800 on ur 1st test! i dont think i can even beat my old score this time!</p>
<p>as 4 da q, i picked A... it waz quiet obvious bcause it was the only choice diff. n there waz not enuff info to pick between B,C,D n E!</p>
<p>Geez! How come so fewer people responded to the November thread? This is crazy! Do that many more people take it in December than November? I find it hard to believe.</p>
<p>For the question about the speed of light, it is definitely greater than 0.6c and less than c. (I didn't take the test, but I can guess that the question was about two spaceships one's speed relative to the other.) There's actually a formula that you can use to solve this problem. I think it's on Sparknotes. But even using common sense, nothing can travel faster than c, and you know the speed must be greater than 0.6c somehow (some of you did direct addition, which is correct only for low speeds but not for relativistic ones!).</p>
<p>for the charge being moved west question...i dont remember the answer it self but it was the one that was above and to the middle of the two charges because the negative sphere will act on it like this \ (pushing up and left) and the positive sphere will pull it down and to the left ... and since theyre same magnitude and same angle the up and down will cancel and u end up with just left...which is west... i believe this is correct</p>
<p>The speed of light question was c, because the speed of light is always c regardless of whatever relativistic frame you take. Did I misread the question?</p>
<p>shouldnt it be greater that c though, because you are looking at it from the perspective of the spaceship and they are approaching each other. Therefore the apparent speed would be, 0.6c + 0.6c = 1.2c.... any ideas?</p>
<p>i ommited 12 questions btw... hoping for 750 +, dya think its possible, how many can i get wrong to achieve this score?</p>
<p>Nothing can be faster than c.</p>
<p>If two objects are travelling at the speed of light (c), they both observe that the other is travelling at c too (relative to them, and relative to anything else travelling at c).</p>
