<p>I’m pretty sure the answer was C or H. I think it was the third choice, but I know that it wasn’t the first or second choices.</p>
<p>Aarrggghh! Yes! That stupid last question about which experiment agreed (or was it disagreed?) with both hypothesis 2 (leaves required) and hypothesis 3 (stem required) killed me. Does anyone remember what the answer was? I think I picked the first one but I can’t remember my reason for doing so.</p>
<p>Oh yeah.
I got that one</p>
<p>it was the one with the</p>
<p>|—4||---------------20|</p>
<p>where 20 ws the dark one. first trial at the top of the second page.</p>
<p>because both hypothesis 2 said at least 10 consecutive hours and 3 said 9 hours for flowering. If you noticed, none of the other answer choice actually flowered. only one of them did, and that was the answer.</p>
<p>QUESTION: What was the asnwer to the one that said from X’s perspective, which trial was Car Y going t the fastest speed. I said Trail 5 with the +1 because the rest were negative and that means the cars are coming closer together which means that cary Y wasnt traveling with much speed as if the distance was growing apart, right?</p>
<p>Whew! That means I got it. As for the car question, I unfortunately can’t help you. I only answered the first question in that passage and then skipped the rest. :P</p>
<p>WongTongTong: I chose the -8 because one car with the respect to the other is always the same for some reason (this doesn’t make logical sense to me) and since velocity is a vector, |v| is speed. -8 has the highest absolute value.</p>
<p>wait, was the 4, 20 Light one experiment 12 or 14?</p>
<p>^ yeah… hats what I was thinking, but If the - sign means they are going…</p>
<p>oh ■■■ me. yeah i think ur right.</p>
<p>oh well, -1 so far. ■■■.</p>
<p>It was NOT 14, it was 12, if I remember correctly. i remember 14 said it didnt flower.</p>
<p>I didn’t understand the last section, with calcium carbonate.</p>
<p>CACBAC</p>
<p>I guessed that. Is it right? ??? :(</p>
<p>lol i have no idea what I put, but it wasnt that bad</p>
<p>for the first one, i assumed that only the CaCO3 reacted with the acid and nothing else right</p>
<p>also, for the second one it assumed that at 14 sec, the pressure stopped increasing and stayed constant?</p>
<p>WTT: It means they’re getting further, so one is going really fast and one isn’t. The thing is, you can’t tell which is which because the CarXY is the same as CarYX. I think you had to look at ZX and ZY in order to find out which is going fast. That seems like a lot of work for a little time.</p>
<p>@WongTongTong</p>
<p>It was actually experiment 10. The question asked for the one that agreed w/ Hypothesis 2 and 3 that SHOULD flower (not necessarily the one that did). </p>
<p>Hy2 said plants needed 10 total/consec hours and leaves to be intact.
Hy3 said plants needed 9 hours and the leaves didn’t matter.</p>
<p>Choice A didn’t fit any criteria.
Choice B, C, D worked for all of them, if you discount the status of the leaves.
However, to answer the question, you needed to look at if they had leaves or not. C and D didn’t have leaves and so by Hy2’s logic, should not have flowered (it doesnt matter what actually happened- just the circumstances matter) – and so are not the answer. B was the only option remaining and worked bc the leaves were intact and received sufficient darkness.</p>
<p>hmm, I dont think it said should, but I could have looked over it. </p>
<p>So is -8 confirmed?</p>
<p>wait what the hell, were the two cars going toward each other?</p>
<p>also, another answer: one of the car questiosns was -4.</p>
<p>Yeah, -8. 10char</p>
<p>For the question that said which hypothesis would be weakened, did you guys put none of them?</p>
<p>^I believe I did</p>
<p>I also put none of them. </p>
<p>any comments on my CaCO3 answers?</p>
<p>So I totally thought that the science this time was REALLY hard. I guessed on alot of it, and alot is an understatement :(</p>
