<p>electroscope was so weird, physics was HARD... epic fail :(</p>
<p>This physics was far harder than october. I sort of liked it though :D</p>
<p>The electroscope one...
Pretty sure the first answer was youd need to know the charge sign scope at the time(they dont provide it).
If you ground the electroscope, it will loose its charge and the strips will hang down without charge.</p>
<p>Few oddball things on the test but overall... 800? Please.</p>
<p>Oh c'mon, I never come even close to finishing these. How do you guys do it?</p>
<p>Last time I took the test I only had time for 54 of the questions and still ended up with a 700. This time I only got to 56 of the questions. Screw college board.</p>
<p>those a-holes call themselves a not-for-profit organization. ********. they should be sued!</p>
<p>Collegeboard loves electroscopes. Learn everything you can about them before the next test!</p>
<p>i agree about the electroscope.u cant know for the first one and the 2nd one is that they will lose their charge.</p>
<p>can u help me wit a couple of questions??
the one about a wave and the distance from the source.it was a I II III question.the answer choices were wavelength frequency and intensity.</p>
<p>and about the metal one with the hole..will it always decrease??thats what i put</p>
<p>The electroscope thing was so weird... Don't they check their wording at all? Someone should put in a complaint.</p>
<p>I think I did OK - I might have a shot at an 800, but no less than 750 :)</p>
<p>from the princeton review 2007-2008 edition:
question asked opposite but same concept.</p>
<p>Question: The circular metal plate has a concentric circular hole. If the plate is heated uniformly, so that the outer circumference of the plate increases by 4 percent, then the circumference of the hole will"</p>
<p>Answer: increase by four percent</p>
<p>"All linear dimensions within the plate - including the radius and circumference of the hole - will increase by the same mount during thermal expasion. To see that the hole does indeed get bigger, imagine that it was filled with a flat circular plug of metal. This plug would get bigger as the entire plate expanded, so if the plug were removed, it would leave behind a bigger hole"
your welcome.</p>
<p>What was the answer to the ammeter/coil question?</p>
<p>I put steady current and held in place, but it was a wild guess.</p>
<p>Also was the answer to the thin film/dark and bright bands question reflection?</p>
<p>@skatj</p>
<p>Your right on the ammeter one!</p>
<p>No idea on that film bands question, it was one of the really odd optics ones I hate :-P</p>
<p>was that the question with like which of the following will NOT occur?
a. reflection
b. interference
c. refraction
d. diffraction
e. phase changes</p>
<p>something like that...i put diffraction</p>
<p>and for electroscope i also put cannot tell and collapse</p>
<p>for the mirrors...i thought he would definitely be able to see down to his knees cuz the mirror went all the way to his waist</p>
<p>Diffraction mos' def.</p>
<p>wait how is it diffraction? just curious.</p>
<p>it was really easy</p>
<p>what exactly was the question? did it show you a diagram of some sort? if it was so easy, i wud have known it cuz i got a 790 last time, im only retaking this bc fizix is mst likely my majro and i want to know it cold. im not even gonna send the score if i get 800 to college cuz it makes no diff.</p>
<p>so what were the answers for the mirror ones?</p>
<p>i only glanced them for a second cause i didn't have enough time</p>
<p>can it be I, II, and III?
and for the second question...
i thought he's gonna miss some part of him if he gets really far...</p>
<p>i thought it was reflection, cause the wave does not get reflected at all right?</p>
<p>btw what do you guys think the curve this time will be? i thought this was an insanely hard test lol..just me?</p>
<p>you think it's very hard?
oh that makes me feel better
i thought physics wouldn't be that hard but i had my last few questions guessed</p>
