***Official Physics B thread 2012-2013***

<p>@chickpeas I put that too, but I couldn’t justify them= hopeless rambling. At least if I get those correct, I’ll still get points</p>

<p>ummmm did anyone else have a different test form? (i forget the order of 2, 3, 4)</p>

<ol>
<li>projectile/can</li>
<li>magnetism</li>
<li>spring lab question</li>
<li>thermo</li>
<li>bubble/buoyancy/refraction</li>
<li>ionization</li>
</ol>

<p>I got 3.49 for the acceleration</p>

<p>i forgot to use the mass of the system but got everything else right for that problem.</p>

<p>What was the work done with the spring? I put 98 J but I have no clue if thats right</p>

<p>Everyone look at page 5 for my answers to everything. Let’s discuss which are right and wrong and try to fill in the missing answers?</p>

<p>isn’t work in J?</p>

<p>you had form b solip. Im assuming you’re from the west.</p>

<p>@Zeruel95 yea yea I put that on my exam thats what I meant</p>

<p>@sattaker if I recall correctly, I put the exact same things for the buoyancy problem, including the justification at the end.</p>

<p>work was 1/2 mv^2. the acceleration was -kx=ma.</p>

<p>whelp… put v goes up t stays constant, p goes down… cruelty thy name is physics b!</p>

<p>God, I’m shooting for a 4 on this. 5% of me wants to blame my teacher for telling us what forms our quizzes and tests were on so we could all look up the answers before the test :P</p>

<p>v cannot go up if work is done on gas.</p>

<p>@eswara weird cause i’m very much from the east… i was panicking because i thought i’d forgotten to do question #7 but i’m almost positive i didn’t have one</p>

<p>I put that the Depth would be the same for the buoyancy problem, because in both cases, the gravitational force of (boat + anchor) are the same, regardless of whether it is on the boat or under the boat. I could be wrong…</p>

<p>I created a chat room to talk about the test:

<p>@solipsis It has nothing to do with your location. There were two different forms. Half the people in my school got each. From what I’ve heard the 7 question form (which i had and though was pretty easy) was easier than the 6 question form.</p>

<p>I think I got a completely different form</p>

<p>I had 7 questions and the first one was NOT fluid</p>

<p>and it was NOT easy</p>
