<p>Oh my gosh. THAT WAS RIDICULOUSLY NOT EASY 
too many hard questions.</p>
<p>Left the superconductor question blank, only one I didn’t answer…</p>
<p>OMG AforAmbition a 750 is a great score, don’t cancel!!!</p>
<p>wait how can u take a physics test for sat??? i thought science tests are on the act or am i mistaken</p>
<p>yea… this was a hard test for me. it brushed on all my shaky topics. mirrors and lenses… history, odd questions im already supposed to know the answers to, magnetic force (bit shake on direction of the force, but i know the field and i well).</p>
<p>What did you guys get for the mirror question: which of the following produces a virtual image, convex mirror, diverging lense, or convex mirror, don’t all of them produce virtual</p>
<p>wait, i’m confused. is it true that if you retake a SAT II and send in your new (improved) score to colleges, you HAVE to send the original one as well?</p>
<p>what was the answer for that one? i put the one that says something …in electrical device in low temperature.</p>
<p>ive heard that its not true. you can just submit the one with the highest score.</p>
<p>The superconductivity one was definitely the electronic device at low temperature. Superconductivity generally only applies to electricity. It can apply to heat transfer as well, but that wouldn’t be that effective, would it, because the superconductor has to stay cold (about -50º C I think).</p>
<p>Like the first questions messed with my head. Were the first 3 AAA. And the Q-, Q+ which ones were deflected to the right, and where were they zero. I blanked harsh.</p>
<p>what the… normally physics thread are booming, did no one take it?</p>
<p>lordfarquaad, i know right?? Those first 3 questions were such bs like why would the test-makers start the first 3 questions (generally the easiest ones) with like 3 trickier problems… thanks… but yeah 3 As I feel better now haha</p>
<p>runningpop, i agree with your 3 answers</p>
<p>The first 3 were A’s</p>
<p>Only the convex mirror produces a virtual image (I think)</p>
<p>For the +Q and -Q question the two points on the outside were both directed to the right. I don’t think any of them were zero because the problem stated that the potential V was not 0 near any of the points and is therefore negligible.</p>
<p>@amayak: why doesnt the diverging lens make a virtual image too?</p>
<p>If i remember the question correctly it asked which ocular devices could make a virtual image on the opposite side of the ocular device. Diverging lens’ can’t make it on the opposite side; I don’t think so at least</p>
<p>1/f = 1/p + 1/q</p>
<p>where f is focal length, p is object location, and q is object location. If f is negative because the lens is diverging, then q will always be negative because object location is always positive.</p>
<p>-q is on the same side as the object for lens.</p>
<p>That’s just what I think</p>
<p>I am so happy the first 3 were A. It legit bugged me the whole test. And or the charges, I think I put none for both questions, but again I wasn’t sure</p>
<p>also, the one with three identical bulbs (2 in series and were in parallel with the 3rd) if the switch were closed, all three would have a change in brightness, yes? and did bulbs x and y have the greatest current?</p>
<p>I wonder if part of the problem regarding the quietness of this thread is that the search function isn’t working and people gave up looking for it…</p>
