<p>I put 2 of the answers down for the last question, one of them couldn’t be found i remember correctly. I think distance, and acceleration were the answers. I put no image for the half convex but that was just my best guess. For the thermometer i put the one with 1 decimal point. The only way to be 100% sure you increase d is to increase v0 (if u increase angle and decrease v0 then it depends on magnitude of change).</p>
<p>for the last one i think we can find them all, cuz there were 3 givens that could lead us to three other unknowns. I put for the thermometer 18.0 same as you
for the projectile one i put increase v0 for the angle we know that the angle that gives maximum d is 45 so i put keep angle unchanged.</p>
<p>All i remember is that I put D for the last question (i did it as time was being called)</p>
<p>Yep, the ball question, you definitely have to kick the ball harder to keep it in the air for a long time and make it travel a longer distance. Changing the angle might do it as well, but you can’t guarantee it with the unknown angle…if it was 45 degrees, then the distance travelled would have been maximum…but that was not given</p>
<p>^^yup thats right.</p>
<p>Too bad so many questions were asking if I,II, I+II etc were true because it made the questions difficult to remember.</p>
<p>I put no image for half convex lens; I drew out the image rays, but I don’t know if I did that correctly. For the thermometer I put one decimal point as well (mine was like 78.0 or something though O_o)</p>
<p>78.02 for me</p>
<p>I don’t think 78 was the thermometer one. I think there were three significant figures questions, the thermometer one, the one with 78 (not sure what i put), and the number of significant figures of an area equal to 21.xxxxx if the sides were given (each to 2 decimal places). I chose 21.xx for that answer i think.</p>
<p>78.02 for the measurment.</p>
<p>significant figures: i chose 21.0, i think. whatever it was, answer was significant to the tenth.</p>
<p>So I thought I would be well prepared for this test, and for the most part I was, but there were some ones I felt eh about. I’m looking for above 740 on this one, but idk.</p>
<p>Btw, do your AP physics scores balance the subject physics? I got a 5 on both mech and E&M for Physics C last year, so Im hoping that’ll offset potential suckage on yesterday’s test.</p>
<p>the last one … i answered you could find two, i think force and the direction of the force, i think you couldn’t find the other one because you needed time.</p>
<p>Bali - a 5 in AP Physics C is definitely more impressive than the SAT Physics. Definitely.</p>
<p>Well crap, I missed the significant-digits-of-21 problem =| Note to self: should pay more attention to significant digits in Physics/Chem classes.</p>
<p>I put all three for the last one..</p>
<p>urggh… i found it hard… I was reviewing out of a Kaplan book from 2003-2004 (only one I could find ANYWHERE!!) anyway… big mistake I think, as the questions on the actual thing seemed really different =S there was one on there about the eV an electron needed to jump to the next level or something… can’t quite remember the question ( I think i ended up skipping it… haha I skipped like 7 and guessed the rest - I’m dead) what did you guys get for that one?</p>
<p>seriously i hope the curve is generous… I hate those I II III ones, all the answers you guys are talking about here I got wrong =(</p>
<p>oh hey… another question. For schools that say last possible test date is December and January will be considered on a case by case basis… could I retake it in January anyway and just hope that they consider it? Or would they dislike that…</p>
<p>They’d probably dislike it; they’ve got a crapload of apps to look at and sending yours in late isn’t going to help the process =/</p>
<p>i think the drum/particle one was speed.</p>
<p>and what was the answer to the spring scale one? is it 0.8 or 1kg?</p>
<p>its 0.8…yeah, the drum/particle one was speed</p>
<p>i put 78.0 for the thermometer and 21.02 for the area measurement, what are the right answers for these two ?
regarding the drum/particle question i dont remember it. Can anyone post the exact question ?
here are some other questions :
- magnetic field near a bar magnet
- electric field on the halfway between 2 charged parallel plates
- convex mirror virtual image
- converging lens all ( virtual , real + and real - )
- man and bird question idk i guessed
- still air no air resistance
- ammeters i think the answers were 2 by 2 ( A1 A5 and A2 A4)
how did you guys answer these questions. if you remember others please post</p>
<p>^I do no think that still air=no air resistance. </p>
<p>For the man+bird one I said that only distance/height was affected. A1 and A5 rings a bell, but i don’t know about the rest.</p>
