<p>for galileo...the answer was expanding universe..he did not prove that the universe is expanding...</p>
<p>duke I think me and you are gonna be in the same place as per scores...because I think I'm gonna hve around 9-15 wrong</p>
<p>but that's above 750 so don't worry</p>
<p>Dude, no worries. You are guranteed above a 750 with a 62 raw score. I don't really know how the curve works, but I do know that approx a 65 raw score should get you 800 or very close. So you're in great shape.</p>
<p>It just sucks guys... let me tell what I had done-- since August, I was preparing. During that last week, I took barrons kaplans and spnotes practice tests and the night before SAT i took the REAL sat ii test.. I score in the ranges of 750 to several times 790s. </p>
<p>I am just stressed. I am in the middle of my gap year. I didnt really get into the colleges of my choice last year. Well I retook some sats after I got my rejections. As of now I have 1480 SAT I (790M, 690 V), 800- Math IIc, 760 Math IC, 720 Latin, 640 Writing.. I just really wanted this physics score after vigorous test prep becaues its possibly the last time I am taking the SAT after having taken it like 6 times. I am applying ED to Duke and I just wanted to make standardized testing a plus when I took this exam..</p>
<p>good luck to all of the rest of you guys.</p>
<p>Best of luck to you as well.</p>
<p>hey what did u guys put for the very 1st question with the pendulum?</p>
<p>It was either gravitational PE or elastic PE</p>
<p>what about the question with the small ball and the big ball falling from the same height at the same time?</p>
<p>I put the buoyant force of air is greater or sumthing like that</p>
<p>gravit 1st one and buyonat is correct.</p>
<p>I wasnt sure about that one. I said something about the mass/sa being greater, bc i thought that if the bouyant force is greater for the larger mass, then it would fall at a slower rate, not faster.</p>
<p>weoooo! {message too short}</p>
<p>woooooooooooooooooooooooooooooooooooooooooooooooooo!</p>
<p>I got it right lol.</p>
<p>agree with adimeola14
i chose the mass/sa</p>
<p>if mass/sa is bigger, then you get a bigger mass, and less surface area. and it means that it is faster.</p>
<p>for the first one, it was gravitational poteintial energy.</p>
<p>I asked the electron question to my (crazy scientist) physics teacher and he said that the electron LOST kinetic energy when it hit the screen.</p>
<p>I put diffraction for the thin layer question.
I am still not sure about gravitational field variation and fractals. (What were the choices anyway?)</p>
<p>totally agree with Von Neumann !</p>
<p>Today, I proved that it wasn't vertical distance; it was the shape OR variation. And it depends on the shape and the variation. If you have a mine below, it changes the gravity dramatically. (I hate test writers)</p>
<p>"diffraction for the thin layer question".it must be correct!
"I am still not sure about gravitational field variation and fractals."i left the fractals blank and, what's the question of gravitatioanl field? i totally forget it...</p>
<p>oh, I did really BAD!!! I left a lot of questions blank. I studied the Kaplan book and I guess it was far easier. :( I don't remember reading anything about fractals?? oh yeah, i left that one blank too. I don't even know if I could get a 700</p>
<p>Trangham;
I have finished kaplan's and barron's; and read through PR and sparknotes. I also solved some questions from Rudman's (It is terrible, anyway). I never saw the word "fractal", too. I knew about it a little bit, because I am interested in the chaos theory for the purposes of IB (TOK).</p>
<p>Bestz;
Which one of the following has the least effect on the horizontal distance that the stone takes (the stone is thrown near the surface of the earth)
-the shape of the stone
-variation in the field strength
-the height that the stone is thrown (this affects the horizontal distance very much, by the way)
I don't remember other choices. (it doesn't matter, I think)</p>
<p>Von Neumann:thanks so much.
I chose "the shape of the stone". i can't think of any relation between SHAPE and HORIZONTAL DISTANCE.
As to variation in the field strength, it means a variation of g, which could lead to the change of time(s=1/2 gt^2, s is constant), causing a variation in horizontal distance(Vx is constant).</p>
<p>Bestz;
I also put the shape, BUT some people say that the question said that the stone was near the earth surface and the variation was too small.
On the other hand, the shape changes the air resistance and may affect the horizontal distance.
Yet, it depends on the shape and the amount of variation whether the shape or variation affect more...</p>
