<p>you guys think the curve will be SUPER generous?</p>
<p>when can we discuss specific questions? the sat II us hist has been discussing them for a while now</p>
<p>the embargo has been lifted, we can start now.</p>
<p>Just curious...
Anyone get four B's in a row?</p>
<p>i didn't even get to see the last 12 questions, i was working at a good pace at first but somwhere inthe middle i started falling behind...i think i left about 15-20 blank overall, and theres a good chance i also got a few wrong. where would that put me??</p>
<p>i don't really remember that many of the questions right now. what sort of concepts are you guys are talking about?</p>
<p>yeah i think i remeber i got a bunch of Bs towards the beginning. i also got a few Cs in a row before that</p>
<p>Yeah! Me too! :)</p>
<p>I guess I'll start...
Anyone get the question that asked about fractal patterns?</p>
<p>I said it was the shape of an insect that was NOT a fractal, but once again i wasnt sure. that was a pretty random question...</p>
<p>I think the answer was the shape of a bugs body, but that question was out of left field. Anyone know the answer about the distance from the earth to a planet when someone is going 9/10 the speed of light?</p>
<p>calculus09 : I totally left that blank. I have no idea what fractal pattterns are:(</p>
<p>What ARE fractal patterns?
Does that even deal with physics?</p>
<p>The equation for length at the speed of light is </p>
<p>length * squareroot(1-(v^2/c^2))
I think...</p>
<p>So the distance would be greater than zero but less than the original length.</p>
<p>What did you guys put for the one with the distance to the planet for someone on earth and someone moving at .9c. I dont think the relativity equations affected the distance to somewhere, so i put the same distance.</p>
<p>Eh....I left that one blank.</p>
<p>Dude! I hope the curve is really really generous!</p>
<p>It was such a hard test! :(</p>
<p>IlDesi is correct. Lorentz contraction would cause the distance to decrease from the point of view of the relativistically moving object. Length</a> contraction - Wikipedia, the free encyclopedia</p>
<p>For v = 0.9 c, the new distance would be 0.44 the original distance, or decreased by 44%.</p>
<p>That question seems advanced for an SAT subject test.</p>
<p>What about the question that talks about light reflecting off a plane mirror?
Was the answer something like "the rays and the normal lie in the same plane"?</p>
<p>All of the answers seemed really similar.</p>
<p>To the previous quesiton directed at me:</p>
<p>I am not saying I will get an 800. My confidence is definitely not that high but I was just wondering what would happen if everything went my way.</p>
<p>And as for the question types not involving much concrete calculations, I thought I was the only one to feel this way and I was simply mistaken. Furthermore, I studied the stuff that my AP phys class did not go over very strenously which was the material relating to modern and heat curves. On the test, I was expecting a lot more questions on modern than I found. I guess luck wasnt on my side this time (and apparently not anyone else's side either since most of us view the test in the same way).</p>
<p>BTW, that one question about fractals made me go ***ffff. What topic would that question fall under? I put the answer as mud since mud cracks are random and wont be able form fractals. I see others put the bug for an answer. I think this is wrong as I remember reading somewhere that bugs do have patterns on their backs but with the way this test was, there is a good chance I missed that question too.</p>
<p>Yes, I said that the rays and the normal are in the same plane.
@skze while bugs may have pattens on their backs it explicitly said the shape of a bug.</p>
