ACT June 2010 - Science

<p>it was 4/40. I am 100% sure. I had like 5 minutes to go and read everything to find this answer. It was like this: D low, I high, E high.</p>

<p>Yea, for English that was right. This is the science thread though.</p>

<p>I put 4.0 40 just because on chart on the upper right of the page I was higher as D got lower (I’m positive) and on the chart below that (two below that?) W got higher as D got lower as well (I’m positive). </p>

<p>Now I don’t remember what the reason the other people said they put 3.0 40 for it may be right but I would assume we dont need any more information that what I’ve just stated. </p>

<p>Fresh, I’m no genius but I’ve gotten a 32 and a 33 composite so far and 35 science once 31 science the other.</p>

<p>For student three, when the ball was moving away from the wall, was the potential energy stored in the string?</p>

<p>No, it was stored in the ball.</p>

<p>^no it was def in the string</p>

<p>Yeah I was about to say, the potential energy is definitely in the string…</p>

<p>Also, does anyone remember exactly what the question was about that had the answer 3:1?</p>

<p>Why, may I ask? When you talk about energy in physics, all the total mechanical energy of an object is stored in the object.</p>

<p>It was the phenotype question with roughly 154 and 47 being the numbers, which results in 3:1.</p>

<p>And 1:3 was definitely one of the choices?</p>

<p>Why, may I ask? When you talk about energy in physics, all the total mechanical energy of an object is stored in the object.</p>

<p>potential energy only occurs if there’s height involved; notice the formula mgh. The “h” part is significant, dealing only with height; that is, the height of the ball. We’re not talking about the height of the ball with respect to the ground. Potential energy in our case is similar to spring energy. If there were a spring attached to the ball, you would definitely say the potential energy is in the spring no? F=1/2kx^2 is the potential energy of the SPRING. If you replace the spring with a string, it’s virtually the same scenario.</p>

<p>Anyone have a guess as to what the curve for the science will be this year?</p>

<p>I know that the science curve is always the harshest… Totally blows. I hope it’s not too bad. If it’s anything like the first practice test in this year’s red book, where -5 is a 28, then I’m screwed.</p>

<p>^i actually think it might be like the first practice test of the RED book. It was comparable in terms of difficulty, if not easier.</p>

<p>What did you guys say for the environmental questions when it asked what can you conclude about the 2 plant thingies, one was below the ground and above the ground. 2 answers had something to do with intake and 2 answers were something else. anyone remember this?</p>

<p>^yea i remember. I put that plant uptake did not affect the results. it was rather the soil by bacterial decomposition or something. If the plant uptake did affect the results, similar results would not result from plants underground and aboveground.</p>

<p>exactly, ok, I said that they did not affect the results either but I think there were 2 answer choices that said…dont remember exactly</p>

<p>^you’re talking about DEA right?
That had nothing to do with anything lol. it was irrelevant.</p>

<p>whats DEA?</p>

<p>it’s what was in the other two options of that question you just mentioned.</p>

<p>If I chose something that said plant uptake did not affect it, was that the right answer? Thats all I want to know lol</p>
