<p>Wouldn’t the first one be included? It asked when the velocity was 0, and at point A and B, it was.</p>
<p>Yea i said first and third i think</p>
<p>^ditto<br>
10 char</p>
<p>Alright, I know this isn’t conclusive evidence on 30,40 vs. 40,40 but </p>
<p>“Stiffness is the resistance of an elastic body to deformation by an applied force along a given Degree of Freedom (DOF) when a set of loading points and boundary conditions are prescribed on the elastic body. It is an extensive material property.”</p>
<p>I highly doubt the test showed an example where more stiffness meant more deformation. If you want max stiffness, you want min deformation, and thus max I and E?</p>
<p>I also put 40 40. It made sense when I looked at the graphs and the relationships given.</p>
<p>I put whatever the highest combination was. If you analyzed the data, it showed that it favored the high numbers of I and E or something. You guys all got digestive system for colon? I saw that and I was like lolwut good thing I know this.</p>
<p>what about the diagram question about exerted force, did you guys put:</p>
<p>left arrow down, middle arrow up, right arrow down??</p>
<p>@Rock- Yeah thats what I put for the same reason.
for the colon one, I flipped out but then i looked at the answer choices and I was like wow…this is a joke. haha</p>
<p>don: it was up down up</p>
<p>^oops, yeah that’s what i meant. many thanks</p>
<p>What happened to the opposing viewpoints of the scientists? It wasn’t on the test and I actually studied for that section >.< I know it was on the April one…</p>
<p>@batpad</p>
<p>H2 came out. Peroxide was made, releasing the hydrogen gas from the water.</p>
<p>clamchowder1^wasn’t that the one with the 3 students</p>
<p>I was so excited for the last few questions because it had the van’t Hoff factor, I was thinking “thank you AP Chemistry”.</p>
<p>I put H2 also because it was talking about oils and I knew hydroxinated oil so I just kind of went with that</p>
<p>Wait, wasn’t it O2? The passage itself even mentioned oxidation.</p>
<p>i though 02 was just normal air, thats why i put it as an answer
then again, science isnt exactly my forte</p>
<p>@LAXer Oh…that makes sense. I didn’t realize it might not always be a passage…the last couple of practice tests and tests I did didn’t not have the passage.</p>
<p>@LAX, that’s what I put. It just said air was bubbled into it. Air=O2?</p>
<p>Why would it be 30 40?</p>
<p>I thought the maximum values for both caused the least deformation. So I just chose the highest values. (40 40)</p>
<p>I think there were just a few pages of mistaken people…scared me.</p>
<p>Consensus should be at 40 40 still I think</p>
