<p>^ Potential difference between two points is just kq/Rb- kq/Ra. For parallel plates, potential is just E(electric field) * d(distance between the plates). Because electric field goes from positive to negative, potential goes from negative to positive. Also, in parallel plates, the electric field remains the same everywhere, which means it is equipotential.</p>
<p>What is the difference between Beta- and Beta+ decay?</p>
<p>Never mind, I forgot I had the internet.</p>
<p>B- is neutron to proton
B+ is proton to neutron</p>
<p>Thanks! I bombed my APUSH test (MC okay, FRQs okay, DBQ…I wrote something completely wrong…wow…) and hoping this won’t have the same fate. </p>
<p>Good luck everyone! I’ll spend my 1-4th periods studying like there’s no tomorrow</p>
<p>I’m international and just took the exam! I thought it was alright, not TOO bad haha Form B FRQs were pretty simple though~</p>
<p>good luck everyone~</p>
<p>I took the form B as well and it was hard like hell</p>
<p>really? well I know I got the one about 2 charged particles wrong probably haha (dunno how much we’re allowed to say right now)</p>
<p>what did you think of the MC in general?</p>
<p>MC sucked cos i omitted 3. lets keep our mouths shut abt this cuz 1. I feel f**kin bad abt this test cos i bombed the FRQ and 2. we are not supposed to say til 48 hrs pass</p>
<p>Just took it. Int’l kid.</p>
<p>Damn.</p>
<p>how soon do tests go onto ap central? because calc and apush are there already lol</p>
<p>so nervous for this. i took a practice last night with formulas* just to see and got a 65 mc so not too worried lol just studying formulas all morning</p>
<p>I think they are posted 24 hours after the last test is administered.</p>
<p>what was form B 
I guess we cant discuss the paper yet… when does the embargo lift?</p>
<p>I bombed the FRQ…seriously…some of the topics I wanted did not appear…by some I mean my two STRONGEST topics I wanted didn’t appear…</p>
<p>48 hours after the exam</p>
<p>I need a miracle to pull a 3 out of my ass! @_@ Good luck to everyone taking the test today!</p>
<p>1 hour till test time, good luck everyone!</p>
<p>crap. they didnt order enough tests so im taking form b next friday…
how anticlimatic. oh well.</p>
<p>Damn I kinda wish that happened to me, but there are like 9 people in my AP Physics class.
-_-</p>
<p>^
there are 5 people in mine…and I don’t think anyone is getting 4 or 5…dam it was hard, wish I was taking the Friday one</p>
<p>you guys done already? or international?</p>
