<p>This test was definitely harder than the one from the blue book. There were too many questions on magnets and waves and not enough on mechanics. I'm predicting 10-15 wrong.</p>
<p>Agree completely... I have no idea how many I got wrong though...time is limited...</p>
<p>hey, you guys did the test ?
Here is 8.00 AM (+1.00 GMT) and the test is about to start.
Could you possibly post as many questions as you rember.
Thanks !</p>
<p>No. Admins, please ban this guy for trying to cheat.</p>
<p>Trying to cheat ? I don't think so.. You see, I'm taking June 2nd not May 5th and the same questions can't appear on two different Physics SAT</p>
<p>So why did you tell us when your test is starting?</p>
<p>cuz i was surprised how could you had done the test when europe time is +1 GMT and USA time is -6 GMT. Normally we do the test before you, no ?</p>
<p>anyone else?</p>
<p>i took it and i ran out of time....... i left two blank at the end but i skipped a lot b4 that too and had no time to go back.............</p>
<p>what do u guys think the curve is gonna be on this one</p>
<p>I took it in october, but the blue book says 59/75 for an 800, so expect about a 56 - 58 for that this time.</p>
<p>the one in oct. was also hard???</p>
<p>ahhhh the curve is different everytime... idk... i have a feeling that im screwed...</p>
<p>can you plz share your oct. score with us and how many u missed + omitted on it?</p>
<p>tx</p>
<p>lol, nah october was easy, then again I was studying simultaneously for the USAPhO before I found out that the test would be all mechanics....and you can't really judge from me since I left 2 blank and got only 2 others wrong lol.</p>
<p>...that's an 800 for all you prodigies about to ask "so what did you get then?"</p>
<p>Argh... that one was impossible. :/</p>
<p>I answered 63/75... my guess is I got ~15 wrong.</p>
<p>I need at least a 650 on this.</p>
<p>i thought it was impossible... im much stronger in mechanics then magnetism and of course, the only day i take it, it has 10x the amount of magnetism then mechanics...</p>
<p>I'll make a list of answers that I know are correct and ones that I'm not sure of.</p>
<p>I know these are correct:</p>
<p>1) Newton was not involved with waves
2) E = V/d
3) W = qV
4) Stopwatch time an error
5) Light intesnity inversely proportional to square of distance, so is gravitational force
6) 500 W
7) Plane mirror for parallel rays
8) Damping causes sound waves to lose amplitude
9) Average readings
10) v = gt
11) Diameter of Earth does not affect gravitational field (only mass and distance)
12) Plane mirrors produce virtual, erect, same size images
13) F = mv^2/R
14) t = 2piR/v
15) F = ma linear relationship
16) F = -kx linear relationship
17) Beats produced by small difference in frequency</p>
<p>I'm not sure about these. Could someone please clarify?</p>
<p>1) Angle of reflection and refraction increase as angle of incidence
2) 5 m/s^2 less than 250 N
3) Node to antinode ratio 1:1
4) Horizontal velocity and time stays the same
5) Length observed to be smaller; time larger
6) Frequency 50 Hz
7) Can't determine heat loss rate without knowing mass
8) Current flows in the same direction when the magnet is moved from left to right
9) GPE 2 times higher for larger mass
10) Speed sqrt2 times higher for larger mass
11) 105 J last question
12) Sine curve for one question
13) Changing wavelength of light -> different color
14) Change the temp of the cold object
15) 1.5 V in capacitor
16) Ball does not curve after leaving tube</p>
<p>I'm going to start crying now.... unless the curve really is 59/75... I'm in AP Physics and I did HORRIBLE</p>
<p>just a few things i noticed for the ones you werent sure on</p>
<ol>
<li>almost definately changes directions, counter-clockwise -- clockwise</li>
<li>mgh = energy which was 15*10 = 150</li>
</ol>
<p>lol omgggggggg i failed that physics test so bad.................. ima get like a 450 while getting a 100 average in ap physics c.... lol</p>
<p>I didn't miss one, but my teacher used to work for NASA, so ya hardest A i ever got.</p>
<p>you didnt miss one?</p>
<p>i hate you
=/</p>
<p>"Newton was not involved with waves"
I thought Copernicus created the heliocentric model...Why is A wrong?</p>
<p>"Light intesnity inversely proportional to square of distance, so is gravitational force"
Illumination = intensity/distance^2, according to Barron's. That means intensity = illumination*distance^2. The answer had to be I only!</p>
<p>"Damping causes sound waves to lose amplitude"
Is dispersion for light waves only? :(</p>
<p>Arghh, stupid mistakes. I can't believe I missed the plane mirrors problem.</p>
<p>By the way, the last one can't be 150J, because if you use conservation of energy, you're ignoring friction. The answer is probably 105J. I put 150J and my friend corrected me. mgh =/= 0.5mv^2 since heat dispersion eats up some energy before the block reaches the bottom.</p>
