April 4 ACT -------- Science

<p>discuss the APRIL ACT science questions..........</p>

<p>I think I really bad the science section. I didnt get the last passages.</p>

<p>this year’s science was easier than last year’s</p>

<p>hey what did you guys get for the question about the upside scale? I forgot the whole question.</p>

<p>Yeah science was really easy.</p>

<p>abc, i think i had the first choice. for the upside down one, the arrow was pointing to the left and the one that was holding it up had its arrow at the three o clock direction… they both weighed 5 if im not mistaken</p>

<p>ya your right^</p>

<p>The bottom scale had 5Newtons showing, as did the top one (it’s own weight). The top one was pointing to the left instead of the normal right because it was upside down. </p>

<p>Anyone get the question in the comet part about “If a sun was found to not have an icy orbiting shell…”?</p>

<p>I said it would have no effect on either experiment, as I couldn’t really see what the sun had to do with any of it.</p>

<p>What did everybody think of the conduction/convection/radiation question? I thought it was only conduction because it was heat traveling through a solid metal tube right?</p>

<p>I put it would strengthen one of them (forgot which one) but I guessed…</p>

<p>yea i put conduction because it’s transferring heat through two bodies. Convection is transferring through a liquid or gas, and radiation is emitting particles of heat.</p>

<p>@min</p>

<p>I also put conduction only</p>

<p>hope thats right</p>

<p>so is it for sure only conduction?</p>

<p>I got conduction only.</p>

<p>the comet questions made me mad… one was: if (the thing that starts with an “O,” opposite of KB or whatever) does not exist, then is student 1’s stance weakened or student 2’s stance strengthened?</p>

<p>what did you guys put? I said no one’s position is strengthened or weakened.</p>

<p>same i put no one’s position is stengthened or weakened cause they didn’t mention whatever the “O” thing was.</p>

<p>it mentioned the O place where long orbit comets arrive or whatever but it didn’t mention stars</p>

<p>idk i said it weakened 1’s cuz at the end of 1’s argument, it said that closeby stars have the same kind of ice and dust or whatever.and yeah, it said that long orbit ones come from the O thing…anyone else say weakened 1’s stance?</p>

<p>i said it didnt weaken either.
at the end of 1 it said some near by starts have that dust stuff, so i figured 1 comet thing not like the others didnt make the argument less valid</p>
