<p>I hope it was parabola coz that's what I put also.
I remember one Q about mirror..The answer was 10.5..right?</p>
<p>I skipped the question about the mirror and the question about the photograph because I have never learned them before in my AP Physics B class, nor have I learned them while browsing my prep. book (it wasn't even in there). Can't help there. o.o"</p>
<p>Does anyone remember any other questions? If so, please post them all.</p>
<p>yep i got 10.5 too, i'm pretty sure it's right.</p>
<p>the asteroid problem abotu which has the longest length, i put the rocket or whatever that was going the slowest (0.1c) but i read in a previous post that the answer was the asteroid. was the asteroid even an answer choice? i don't remember seeing it.. but if it was one then yah that would be correct. ugh so many careless mistakes :(</p>
<p>I remember a Q with a squared box ..with a hole ...I dont remember exactly the answer...but i know that if the box decreased..so did the hole...and if the box increased so did the hole..right?</p>
<p>Another Q was with graphs ..something with constant v and then decreased speed...so i choose the graph with the acc 0 and then a decreasing downward below 0 in an oblique line..sorry if i didnt explain this propery..:p</p>
<p>Yes, the hole expands if the entire thing expands and vice-versa.</p>
<p>yes that was what i got too :D</p>
<p>Crud. I remember that "asteroid" was a choice but I picked the rocket moving at the slowest speed. Aargh. I got the asteroid problem wrong.</p>
<p>..</p>
<p>8 + 3(0.25) = 8.75</p>
<p>That brings me to: 66.25/75</p>
<p>Eep.</p>
<p>you omitted 8?? didnt have enough time or just didnt know the answer?</p>
<p>I omitted 5, got 3 wrong. Now I can only get 2 more wrong to still be eligible for an 800. :( I hope the curves are nice.</p>
<p>Of the 5 I omitted I remember 1 was a mirror question, the other a photograph size question, and one more was the very last question. The other 2 I can't remember. The ones that I skipped I either really had no clue or had never learned about before.</p>
<p>Do you remember any other questions?</p>
<p>I only tend the remember the questions i spend alot of time on..... Looking at this thread, I think it probably has covered all the hard questions in the test already :D</p>
<p>Btw I noticed that the fractal question answer is the insect? Does anyone know why? I have only did a project on the fractals in a snowflake, and nothing else apart from that.....</p>
<p>It's the insect because the pattern of the insect does not extend infinitely..</p>
<p>I picked mud because I didn't know that dried mud's cracking has a set pattern or that it extends infinitely. >.<</p>
<p>I picked mud too, because I remember my math teacher telling me how fractals is present in almost every phenomenon is nature ie. animals... (insect)</p>
<p>I did not see a single question about fractal in the practice test, neither did i see it in the SAT Physics prep book..</p>
<p>Yeah, I put down mud too, because I thought it wasnt uniform. Bah. </p>
<p>And oh, from wikipedia:: When light reflects off a material denser (with higher refractive index) than the external medium, it undergoes a 180° phase reversal</p>
<p>Since it reflects off the bubble from air, it goes through a phase change of pi. Definitely diffraction.</p>
<p>I put diffraction too... I think...</p>
<p>Ah. That was the fourth question I skipped.</p>
<p>Okay does anyone know for sure that "insect" is the right answer for the fractals question? I've found information contradicting both now. T_T And most people I've asked put down that dried mud is the answer..Can someone please confirm from sources other than what other people say? Like a textbook or something? .. Thanks</p>
<p>Well, I'm hoping on dried mud. Dried mud...</p>
<p>According to <a href="http://www.wavecrestdiscoveries.com/articles/fractals.htm%5B/url%5D">http://www.wavecrestdiscoveries.com/articles/fractals.htm</a></p>
<p>=></p>
<p>The nested, recurring patterns of fractals are very common in nature. Examples include: the tight spiral of a coiled fern head, cracks in dried mud, lacy frost on a window pane, the rhythm of dunes and the ripples on their surfaces, spiral arrangement of galaxies.</p>
<p>Insect is correct.</p>
<p>I don't see how mud patterns are recurring and whatnot. Bah. It's not fair!!! T_T <em>wails and sulks and whines</em></p>
