<p>the pulley one is 2W</p>
<p>half the ppl are saying 2W half the ppl are saying W</p>
<p>Granted, it makes no sense that collegeboard would ask about the rope supporting the pulley... but maybe they threw on on there to trick people.</p>
<p>I'm pretty sure it's W, we spent an entire 2 weeks in class on tension, so yeah W</p>
<p>nono that's not the problem... the problem is WHAT string's tension are we talking about lol.</p>
<p>dang, this is really throwing me off b.c if that many people read that it was the rope supproting the pulley, than i am inclined to believe that it a trick question. screw the sat2</p>
<p>yes, really low blow by them lol...</p>
<p>ahh well. test is over =)
hopefully we'll all get the scores we want (or need) haha</p>
<p>Jw how many people started posting on cc just after the test</p>
<p>I certainly did</p>
<p>my last 12 posts were about this test haha</p>
<p>13* including this</p>
<p>me! </p>
<p>and if you remember more questions please post</p>
<p>wow... so I'm at 7 ommitted and 7 wrong which puts me at a raw score of 59. Not the best time for my worst test :(</p>
<p>lol i could probably remember another 10-20 questions... but do you seriously want me to just ramble like that</p>
<p>it would be doing me a huge favor to ramble on like that, i'm deciding whether to cancel or not. hah (pathetic i know :()</p>
<p>same here. please do ramble =) i would really appreciate it haha</p>
<p>ok well... here i go</p>
<p>a light ray incident off a plane mirror is always in the same plane as the normal of the mirror</p>
<p>Ray E is drawn incorrectly, since the incident ray should bend AWAY from the normal at the lower water/air interface</p>
<p>none of the quantities given for the graph of KE v. time are zero... all of them are nonzero</p>
<p>The graph of the car with the highest instantaneous acceleration is A (the one that looks like a normal curve), the one with the ihghest distance travelled is D? (the one that is higher than all the rest but doesn't peak like A). </p>
<p>At time 3s, the ball is at speed = 0, acceleration = -9.8. At time 6s, the ball is at speed = 25 (w.e the initial speed was), acceleration = -9.8</p>
<p>momentum is conserved in all cases</p>
<p>maximum stretch of spring can be done by setting initial kinetic energy to maximum potential energy in spring</p>
<p>the wind exerts a force of 500 on the hot air balloon</p>
<p>constant current with a nonmoving coil will result in no induced charge (no deflection of needle on galvanometer)</p>
<p>resistance of 6 ohms = 12ohm and 4ohm in parallel, and that in series with 3 ohms</p>
<p>charge 3 should be moved right 2cm to make net force on charge 2 zero</p>
<p>guitar string, only wavelength stays constant</p>
<p>expanding universe, doppler shift and pervasive radiation</p>
<p>the centripetal force of the string is highest when the pendulum is at the bottom of its swing</p>
<p>the force up the incline will induce a constant velocity when F(friction) = F(parallel), F(normal) = w(perpendicular)</p>
<p>after an inelastic collision, the final velocity is 1.5m/s. After an elastic collision, the cars just switch velocities (3 and 6 become 6 and 3).</p>
<p>Out of the three rotating wires in a magnetic field, only I and II will have induced current.</p>
<p>Maximum force occurs when a wire is situated at a 90 degree angle with a magnetic field.</p>
<p>charge A and B have the same sign charge (for the problem when they give you the trajectories of charges A and B between parallel plate capacitor)</p>
<p>total charge = 3600C for 2 amperes and half an hour</p>
<p>blue light has a higher FREQUENCY than red light</p>
<p>ball can be thrown 6 times the height...</p>
<p>the sun will move the earth more than the earth will move the sun AND the earth moves at different velocities around the sun</p>
<p>heat engine efficiency is 0.6</p>
<p>heat engine expels 200J</p>
<p>if two differently temperatured (whoa i made up a word there) objects are put into a closed system, entropy must increase.</p>
<p>the centripetal force of the whatever is 5N</p>
<p>the penny is 6 times as big</p>
<p>specific heat relates Q/m*deltaT</p>
<p>heat of fusion is the heat required to melt a solid per unit mass</p>
<p>the sine curves that are slightly weird and not on top of each other would show destructive intereference</p>
<p>the sine curves that start at 0,0 but travel at different lengths are at different frequencies</p>
<p>you can get FREQUENCY from just knowing the period</p>
<p>the tension is EITHER W OR 2W depending on *** collegeboard asked</p>
<p>when the string is cut, the ball will fly off TANGENT to its circular path (i think c)</p>
<p>the wall losing heat question is smallest surface area, largest thickness</p>
<p>satellite doesnt crash to earth because its tangential velocity balances gravitational force</p>
<p>39 and counting</p>
<p>ugh... if i remember ne otherss ill post</p>
<p>woww thanks a bunch, this helps a lot. now I'm at -8 total, 0 omit. So I'm teetering between an 800 on a generous curve and a 780 or so on a regular curve, 760 on a harsh curve or so...</p>
<p>haha assuming i'm right on those <_<</p>
<p>-8 is a 780 on a regular curve and a 760 on a harsh curve? What?? The CB book says a 63 raw score is 800.</p>
<p>seriously though, you are more than enough confirmation for me :P thanks again. </p>
<p>so yeah, i guess my score all comes down to the curve.</p>
<p>well I anticipate the worst, this is october test meaning all the people who took prep classes over the summer...</p>
<p>I picked up a kaplan book in august and read it from then until now, without a physics class or anything.</p>
