<p>I still think the spring question was static friction. The block has a tendency to move with the wheel due to static friction, which is the force with which it is pulled with the wheel, away from the spring scale, stretching the spring.</p>
<p>There was a question that asked for electrical force nd the answer was 4.5 x 10^-4 N.</p>
<p>Yeah I’m pretty sure it was static and the pulley is definitely 2W. It asked for the tension not in the pulley system, but in the string holding up the pulley and the two blocks.</p>

<p>@justPhysics</p>
<p>Yea it was like #71 and there were also:</p>
<p>Resonance is 56
Wave nature or light is slit diffraction experiment</p>
<p>Wave nature of* light</p>
<p>JustPhysics,</p>
<p>I’m sure tension was 8 N because the friction force was 8 N.
The F vs x diagram… I’m not sure whether work was an answer choice but it was something with unit of energy</p>

<p>Do you remember what the other choices for the wave nature of light were? I thought I put something different but I think the slit experiment is correct. And do you remember the question with 2F or two times the force? Or the current question with the square wire in a magnetic field? </p>
<p>I decided not to cancel but I am right on the edge with 5 omitted and 9 wrong I hope I got the 800. I think the curve might be better than the 59 that’s in the college board book and we are only missing 15 questions which are probably mostly easy ones…</p>
<p>What was the answer for the question with a bar whose ends were both attracted to N-poles of magnets?</p>
<p>What were all the options for that question?</p>
<p>i forgot… i think like temporary magnet, magnet with two south poles, magnet with two north poles… i chose the magnet with two south poles but i think thats wrong cuz a magnet must have a south and north pole… nothing else seemed to work though</p>
<p>Yeah that’s got to be wrong…was there a two south poles option too. I guess I chose the temporary magnet or something…</p>
<p>I was wondering if you could post how you’re doing…I want to get an idea of what the curve will be like and stuff</p>
<p>I have 5 omit and missed 9 maybe 10
A vs. B^2
Energy is infinite
Area under F vs. x graph
Photoelectric effect
Wave nature of light
Zero
Zero
Velocity V = 2pir/t
Q/2 (was there another question on this?)
Maybe the static vs. kinetic friction…</p>
<p>What about you</p>
<p>omit 10:</p>
<ol>
<li>0 and 0 charge</li>
<li>where you can see light</li>
<li>where light is white</li>
<li>rotating wheel</li>
<li>speed on the loop if radius is doubled</li>
<li>MR the change in kinetic energy</li>
<li>star question</li>
<li>wall and heat</li>
<li>magnet pulled through coil?
dont remember the 10th one</li>
</ol>
<p>4 wrong:</p>
<ol>
<li>rider maximum velocity</li>
<li>induced current</li>
<li>this magnet question</li>
<li>maybe question with 2 rings and magnetic field</li>
</ol>
<p>oh yeah i skipped the question with two ropes and frequency</p>
<p>and also, i thought the energy question was the answer with square root of 1- v^2/c^2 as denominator</p>
<p>and also, whats the answer to the question: what is the magnetic field in two parallel wires on top of another with currents going in opposite directions? in the top wire the current was going right and in the bottom wire the current was going left</p>
<p>This v^2/c^2 in the denominator is the correct answer - it just when you take the limit means that the energy goes to infinity.</p>
<p>The one with the two wires and the mag field was twice one mag field going into the page, I believe. X’s were in the middle, created by both, if that makes any sense…</p>
<p>Damn youre right on the edge too. Was the 0 and 0 one or two questions?</p>
<p>And for the two loops I put the field went to the right since it would oppose the field of the first…</p>
<p>JustPhyscis. The field of the one in the picture WAS to the right in the picture, right? I am absolutely sure that the B was drawn to the right, and the north side of the magnet was coming toward the center of the two loops</p>
<p>Yeah you’re right now that I think about it…</p>
<p>I’m canceling my scores…I’ve just missed too many and made too many mistakes…I’ll just take it next month with math II and have time to go through PR and then Kaplan again.</p>
<p>God, this looks hard. I’m not taking this test for a while.</p>
<p>Are you sure justPhysics? Especially since this test was so hard, the normal curve will be skewed score-wise, with a 780 probably at a 55 raw score. I don’t quite agree about the electroscope one though, since I believe the question said “an electroscope is brought close and then removed.” This would be asking about the whole process of bringing it closer (theta decreasing) and then moving it away (theta increasing). Also, does anyone remember for the magnetic field double loop one if they got an answer that implied that B reverses to the left and the current reverses?</p>
<p>The electroscope was negatively charged. A negatively charged rod was then brought close to the toroid, causing the negative charges lingering in the top of the electroscope to flee away to the leaves; more negative charge in the leaves would push the two leaves farther from each other, thereby increasing theta proportionally.</p>
