<p>"the centripetal force of the whatever is 5N"
hmm... what question was this?</p>
<p>lol i'm just so descriptive</p>
<p>it was like, a car weighing 0.1kg goes 5m/s around a track of radius 0.5m. what is the centripetal force.</p>
<p>ah... yes... well, I got all of those questions, so maybe I'm not completely screwed. :)</p>
<p>rutherford's gold foil experiment = some particles were completely deflected</p>
<p>isotopes have different nmbers of neutrons</p>
<p>neutrons can get close to atom cuz they have no charge</p>
<p>the electron will bend DOWNWARDS in that magnetic field</p>
<p>the western net force will occur between the two point charges and above them (choice C)</p>
<p>the halflife is 1 hour, 20 minutes</p>
<p>the particle is between 0.6c and c</p>
<p>the 20 ohm resistor will heat up to h/2</p>
<p>the most charge will come out of the pointy end of the current-filled wire</p>
<p>all point charges will have the same force on them</p>
<p>the force is equal to 2E-3 N</p>
<p>50 and counting</p>
<p>ok im going to take a rest, maybe play some video games, etc.</p>
<p>I don't know the answer for sure, but there was also a q involving eVs. I think it was that the wavelength is halved, so the eV jumps from 2 to 4 eV.</p>
<p>Also, when you switch from shining yellow to green light, the frequency and max KE changes.</p>
<p>Another one already noted in this thread (I think), single-slit defraction results from interference.</p>
<p>There was also one with a point and a plane mirror and the q asked which point signifies the reflection. I bubbled B on that one as it was symmetric to the first point with respect to the mirror. </p>
<p>So, there's 54... just 21 more!</p>
<p>lol yeah we're getting there. I'm still at -8... thanks so much for the help guys </p>
<p>and yeah, video games, i'm going to go write a column for school paper, then watch my taping of the A's losing to the tigers :(</p>
<p>wow dude major thanks man. you're freakin incredible LOL how do you memorize all that? the test must have been cake for you haha</p>
<p>damn.....-10...4 blank = 59 raw score = around 780 or 770
anything above 740 is good enough for me but below that will look bad</p>
<p>yeapp same here dude lolll</p>
<p>1 omit + 5 wrong.....is it possible to get 800?</p>
<p>i ran out of time for phy test today...but had 30 mins left for math2..so i just went back to phy test...</p>
<p>PHYSICS was sooooooo hard!!!</p>
<p>PR physics book sux.....</p>
<p>will it really make much of a difference between a 790 and an 800?</p>
<p>and from my vague recollection, 60/75 yielded an 800, but that could be different from test to test</p>
<p>i think i'm sitting at 62/75... depending on whether i answered the guitar question correclty and whatever that KE graph question was (i'm not sure, so ill just assume it was wrong just for worst case scenario purposes)</p>
<p>i remember in PR or Kaplan it was like.. 62 was it for 800... would 790 make much of a difference?</p>
<p>was this test hard?</p>
<p>62 = 790</p>
<p>and colleges will see 790 as 800. Its not that big of a difference.</p>
<p>naidu90, I think there were a few tough questions but the biggest problem was time management. I think with good time management on this test, I - and many others - could have gotten an 800.</p>
<p>yes definetly. time management was a big problem. I wouldve definetly gotten an 800 on this one. The June one might've been a little harder though.</p>
<p>One more question from the test:</p>
<ul>
<li>The part of the KE vs. time graph with 0 slope was teh one with constant velocity.</li>
</ul>
<p>20 more to go...</p>
<p>Also, can somebody clarify the eV question for me?</p>
<p>The part of the KE vs. time graph asks about which interval has 0 velocity, i think i put none of the above.</p>
<p>There was 1 point where KE = 0, hence velocity = 0.</p>
<p>1 point or 1 interval?</p>
<ol>
<li><p>Was the electron pointing down in the generator or soemthing for that one problem?</p></li>
<li><p>Did you guys get B and C in THAT ORDER for the first 2 questions of the test involving the different graphs of frequency variations?</p></li>
<li><p>For the Rutherford Goild Foil Experiment, do you guys remember the other answer choices because I know I put something starting with "some particles" but I'm not sure if there were other answer choices phrased like that?</p></li>
</ol>
<p>I think worst case scenario, I'm going to get about 20 wrong and I left 4 blank. My goal is just to break 700 though...</p>
