<p>LOL did i say 5? i meant 800 =PPPPPPPPPPPPPPPPP</p>
<p>haha yes definitely more than 8 wrong u can still get a 5 on the AP eexam ^^^^^^^</p>
<p>*** the timing of my posts are screwed upppppppp</p>
<p>i'm confused.. :(</p>
<p>the official sat study guide says u can get up to 59/75 raw score and still get an 800 and sparknotes and the princeton review both saw somewhere around above 60/75 is an 800</p>
<p>^^ I agree.
The PR says that you can need at least a raw score of a 60 to get an 800.</p>
<p>ok, so 12 wrong should be fine :D - b/c of the -1/4 per.</p>
<p>I'm taking it. I've never taken a physics course nor have I begun prep. I'm such a great student!</p>
<p>^ the ideal one!</p>
<p>the physics is REALLY hard though. 60/80 should be difficult to get -.-</p>
<p>I think i got a 3-5 on the AP (i'd rather be modest then thinking i did too well) and the AP didn't prepare me at all for the SATII, there was a LOT LOT of modern on it.</p>
<p>whaa. i was looking at Physics questions and they seem easier than Bio or Chem?? :confused:</p>
<p>No, physics is a LOT harder than the Chem test.</p>
<p>si, I agree!!! physics is the hardest science subject out there!</p>
<p>Physics is where the men are separated from the boys (assuming you're male).</p>
<p>^lmao.</p>
<p>ah okay. i guess i was looking at the easier questions then??? :still confused: :confused:</p>
<p>Narcissa, I think there might be a bit of exaggeration going on here. Physics isn't THAT much harder than bio or chem, but you may have to go through a whole practice test or something to see the difficulty.</p>
<p>Then again, where are you getting these practice questions? If they're from Kaplan, it explains why they may seem easy.</p>
<p>yea, kaplan's are a bit easier, imo. Narcissa, I think that Physics is a little easier than Chem and Bio. IDK what others think.</p>
<p>General Thought: It shouldn't matter if it's easy or hard. Most of you should have enough background in physics to at least be somewhat familiar with the material.</p>
<p>There are around two and a half weeks until the test. It's up to you whether or not you're going to pop open the princeton review book, go through the whole damn thing meticulously, understand all the concepts, memorize all the equations, do/look at the solutions to all the sample problems, and then proceed to take every challenging practice test you can find. An 800 will be waiting for those who want it.</p>
<p>You guys need some practice. Here's a tough one, if you're ready for it.</p>
<p>A pendulum with length 1 m has a mass of 1 kg at
the end. The mass has +200 micro-C of charge. An
oppositely charged identical mass sits 10 m
directly below the lowest point of the arc of
the pendulum. What is the period of oscillation?</p>
<p>A) 2.5 sec
B) 1.9 sec
C) 1.8 sec
D) 1.7 sec
E) 1.5 sec</p>
<p>Hint: the charge effectively makes g bigger.</p>
<p>For a pendulum, the period T is defined as T = 2pi(L/Atotal)^1/2. The mass is irrelevant. </p>
<p>L = 1 m. Atotal = g + a(electric). </p>
<p>g = 9.8m/s^2, Fe = k(200)^2/r^2 = ma, so a = k(200x10^-6)^2/r^2</p>
<p>r, the distance between the amplitude of the pendulum, is not supplied, nor is an angle....so, is this an impossible problem? </p>
<p>I can still eliminate a few choices. So, without electric force, the period T would be:</p>
<p>T = 2pi(L/g)^1/2 =~ 1.99 seconds. So the period has to be less, I would guess 1.5 seconds, given that we're dealing with micro-coloumbs.</p>
<p>I'm probably wrong though =D</p>
