<p>hmm…I remember it being 1-2 yrs. I could’ve gotten it wrong. Do you guys think the science curve will be easier this time around?</p>
<p>sigh Ny i also got 1-2 but i’ve learned that when the majority says an answer and just two say 1-2, we’re probably wrong.</p>
<p>do you guys remember one of the springs question: is the force of gravity or the strings greater? & why?</p>
<p>Spring, because it went up. If gravity’s force was stronger, wouldn’t it have gone down?</p>
<p>Springs because it moved upward from point R.</p>
<p>i said gravity, no idea why. This maybe incorrect but i think k<G</p>
<p>The hardest questions were the one that asked about the proteins - it didn’t even say what made them but I guessed ribosomes since I remembered that from bio last year. Also - was 0 degrees the average for the graphs? That confuse me as it did not state it…</p>
<p>i put 0 as the average</p>
<p>for the question about 1-2 years, the graph did dip below 1 between 1 and 2 years after the eruption, then it went back up above 1 degree</p>
<p>therefore the answer has to be between 1 and 2 years after teh eruption</p>
<p>i didn’t think that was the case at 16 km…</p>
<p>the graph was below only before the eruption. the eruption was two years after the start of the graph and 3 years were graphed after that, so it was 3+.</p>
<p>Was the spring one answer a or b?</p>
<p>The answer to the spring one should be gravity because it went down. The spring started 0m from point R, according to one of the graphs that looked like the absolute value of sinx. As a result, moving away from point R, on the ceiling, would mean moving down. Gravity is stronger than the spring force.</p>
<p>^ The question asked, when the spring was released, which force was stronger. Since the spring shot upwards, the spring’s force was stronger than gravity’s. If gravity’s force was stronger, the spring would have went down even more when released, which it didn’t.</p>
<p>The graph started at 0 (distance from point R) because point R is where the spring was pulled down to. Immediately after being released (at point R), the spring went further away from point R (up).</p>
<p>Point R was below the point where the spring was hanging, not above.</p>
<p>I really thought point R was where the spring was attached to the ceiling. Well, I hope the science curve is REALLY lenient.</p>
<p>The volcano question was greater than 3 years. I remember specifically</p>
<p>0 was NOT the average temp, it represented the average temp change (or something like that).</p>
<p>For one of the questions on the one dealing with the temperature change with the three balls, it asked what the final temperature would be if they let it cool all the way down. I know someone already said 20 deg. Celcius but I thought it could have 22 deg Celcius as well. It seemed like the two were extremely close…</p>
<p>Anyone care to elaborate or explain why it’s 20 deg. Celcius?</p>
<p>Also, just a side-note:</p>
<p>I didnt choose 22 as a complete guess. I SWORE that room temperature was 22 deg Celcius…and wouldnt the ball cool all the way to room temperature?</p>
<p>I was almost positive it was 22 degrees because I drew the line and it was about 24 degrees where it ended.</p>
