The Science Thread for ACT December 2009

<p>it was the last question of the left column on the last page… so third to last?</p>

<p>ok</p>

<p>So here is what I think:</p>

<h1>38: A</h1>

<h1>39: C</h1>

<h1>40: ??? Does anyone remember? I blindly guessed D.</h1>

<p>do you remember the question for the last one? any curve predictions?</p>

<p>im hoping -1 is a 36</p>

<p>i think the answer choices were: </p>

<p>A. A will have a higher I because its average distance is longer than that of B.</p>

<p>B. A will have a higher I because its average distance is shorter than that of B. </p>

<p>C. B will have a higher I because its average distance is longer than that of B. </p>

<p>D. B will have a higher I because its average distance is shorter than that of B. </p>

<p>its either a or d…</p>

<p>@silence</p>

<p>is that the 3rd to last question or the very last question?</p>

<p>i think i put A for that one because according to the tables the longer the object the higher the inertia.</p>

<p>also inertia = mr^2 so the longer one will have a greater radius which makes its inertia higher</p>

<p>@vault</p>

<p>r u referring to the 3rd to last question or the very last question?</p>

<p>it was the third or fourth to last… not the last question</p>

<p>@ vault - i too wish to see all the science answers… i was only unsure about the one i asked about… did you actually read in the passage that the longer it is the higher the inertia? i dont remember reading that but i skimmed it</p>

<p>I dont think it was in the passage, but it could be inferred from the data provided.</p>

<p>Did anyone put “D” for the very last question?</p>

<p>the last question was A, which was CH4 or methane, whatev you want to call it. It was the only one that was a hydrocarbon</p>

<p>I thought the question that involved methane was in the passage about the production of petroleum? There was another question about it?</p>

<p>If I remember correctly, the last passage had to do with pendulums.</p>

<p>yeah last passage was about inertia stuff. ch4 passage was like in the middle</p>

<p>do yall remember the question from the mosquito passage where it asked how to control it to where the mosquitoes werent attracted to certain tents or something? anyone remember the question and the answer?</p>

<p>yeah, it was move the people into different random tents, that way if they kept going to the same tent, you’d know that it had nothing to do with what the people were infected with.</p>

<p>Does anyone remember what letter choice they put for the very last question? D?</p>

<p>what was it asking?</p>

<p>not random tents in my opinion zlz… if they put each one in a random tent i dont think that would help vary the results. regardless of what mosquito was in there they’d go to that same tent. just my opinion</p>
