<p>In the conflicting viewpoints passage, what was the order of the substances from smallest to highester molecular mass according to Student 1?</p>
<p>I think it was water is smaller than iodine gas is smaller than the oil thing</p>
<p>names might be wrong but pretty confident that is the order</p>
<p>Andrew, that’s right</p>
<p>i thought that this science was easier then the last, however it had a lot of questions of actual knowledge in science questions…did they do higher altitudes for less gravity? and also was the dunes amplitude and wavelength?</p>
<p>Dude wasnt the equation H divided by Y</p>
<p>I think the ACT is easier to guess on – it tends to happen more often than the SAT where your gut instincts are correct. On the SAT they generally try to lure you into a trap if you follow your gut instincts.</p>
<p>@noxsing – I put it would lower gravity…it was either that or lower air friction and I don’t think it would alter air friction. Considering the extremely high altitude of the moon has lower gravity it makes logical sense…</p>
<p>@bulls7395 - it was y divided by H</p>
<p>It’s lower air friction. It said that in the opening statement. Plus, the gravity is relatively constant on Earth.</p>
<p>Bouncing ball was .5 </p>
<p>It said a 2m height, so you have to use the equation 2(.55)-2(.33) = about .5</p>
<p>The moon has lower gravity because of smaller mass, nothing to do with altitude. The higher altitude was to increase gravity I’m pretty sure.</p>
<p>@Iris the reason i didnt put lower air resistance was because the passage didnt state that it was BECAUSE of the high altitude (and not to mention all it said was the resistance remained constant). i think the high altitude was to get the most acceleration, and therefore to increase the gravity.</p>
<p>You may be right, efeens44. I don’t trust myself. @.@</p>
<p>Gravity would decrease further from the core of the earth, not increase, so how would that make sense?</p>
<p>Also, gravity is a constant in almost all problems in general</p>
<p>What was the one that proved that the acid wasn’t the right one? I put it was less than the halfway point but I didn’t know</p>
<p>yea, g decreases with higher altitude, there was an answer for that,right?</p>
<p>Acceleration would be more likely to reach 9.8 m/s^2 though so wouldnt they bring it higher to maximize their data? I may be wrong.</p>
<p>Uscolleg, in the opening statement, it told us that the Px of the things was equal to the halfway (or equilibrium) Ph of the one on the graph, I think.</p>
<p>I also don’t think the gravity would make sense because no matter what altitude you test at, the gravity will be constant for all values. For the air resistance, it could affect some balls differently.</p>
