<p>exactly the same with me. i think its because i have taken AP biology but havent taken physics yet…</p>
<p>what was the control?</p>
<p>I still don’t think the initial amount of H2O was 12%. That’s far too low. If it said how much was lost over time, then yes, 12%, but it asked what the INITIAL amount of H20 was… Anyone want to back me up?</p>
<p>so what was the answer to the estuary one?</p>
<p>Had to be 12% water because the liquid(s) went from 100% to 88%, and the formula went from something like CaCo3+H20 to just CaCo3…</p>

<p>And on that note… would anyone care to tell me what your best guess of a -3 would be?</p>
<p>^ 33 or 34…</p>
<p>For the student 1, student 2, and student 3 ones I think I answered Students 1 and 2 were right, because I didn’t actually read all the way through!</p>
<p>I completely forgot that if two objects start at one height they end at the same height regardless of mass! But then again didn’t Student 3 say that KE and GPE weren’t dependent on mass? 'Cause that’s wrong, the formulas for each are 1/2mv^2 and mgh respectively.</p>
<p>it doesnt matter whos right and whos wrong; those are their theories. unless it asks you “whos right?” you just need to know what each “scientist” believes. and the answers were there were two separate “student 3 only” answers</p>
<p>Okay good! Cause I had two where I answered student 3 only, and the others I answered students 1 and 2. I’m hoping I only got 2-3 wrong on the science, but who knows. </p>
<p>2100 on my SAT, how would that reflect back on the ACT?</p>
<p>@zach12: You sure about that? I’d be thrilled if I got a 33 on the science (it’s my worst section), but I feel as though the science curve is super strict. I took a few practice tests where a -2 was a 31. </p>
<p>@Boxy52: A 2100 on the SAT is about a 32 (2120) on the ACT.</p>
<p>Hmm I can’t remember pretty much any questions/answers for the science section…oh well…i’ll just have to wait 2 weeks and a couple of days :p</p>
<p>Boxy, i think there were only 2 questions that asked about the students, and the answers were both student 3 only…</p>
<p>@liv4physicz Going back to your previous question, I think the control was the one without any of the grass stuff in it.</p>
<p>Hey guys one question was really bothering me it was like would bla bla be greater or less like on the moon than on the earth</p>
<p>I said it would be less on the moon because the acceleration due to gravity is greater on earth? agree or disagree?</p>
<p>@peterfig95 That’s correct.</p>
<p>Can someone explain the 88k question? I can’t seem to recall it.</p>
<p>the control was the one without the grass</p>
<p>so was the estuary answer salt water at the bottom or fresh water at the bottom?</p>
<p>pretty sure it was salt water at the bottom
because the intro paragraph said something about how the fish initially lived in the Hudson Bay which is a mix of salt and fresh</p>
<p>I think 88k was the range in which material y was a superconductor
could be totally wrong</p>
<p>I’m kind of confused about the heat produced by the superconductor if R = 0. Doesn’t there have to be some sort of resistance for there to be any current? I = V/R? If R = 0 then it’s undefined? No current = no heat? ^.^ (I’m just being desperate)</p>
<p>well you’re assuming x/0=0
which isn’t true
it’s really more like infinity. I mean, how many times does 0 go into x? An infinate number of times.</p>
