<p>constants are given to you on a little sheet called the constants sheet</p>
<p>you dont need to memorize planck’s constant, the work function for every particle, boltzman’s constant, etc…</p>
<p>**** dead piggie</p>
<p>yeah, but on every released physics test, there has been at least one question where you needed to know some obscure constant that was not provided on the green sheet</p>
<p>A sample of an ideal gas is in a tank of constant volume. The sample absorbs heat energy so that its temperature changes from 300 K to 600 K. If v1 is the average speed of the gas molecules before the absorption of heat and v2 is their average speed after the absorption of heat, what is the ratio v2/ v1 ?</p>
<p>sqrt 2.</p>
<p>(10char)</p>
<p>can u explain that?</p>
<p>v=sqrt (3RT/M)
If T is now DOUBLED. v increases by square root 2. This is also the ratio.</p>
<p>Take a look at the rms velocity equation.</p>
<p>oh ok thx!</p>
<p>lets get the day started with some good ol’ physics guys</p>
<p>nah… I give up. This test is going to be awful :[</p>
<p>I literally just started studying for this 10 minutes ago. I am BEYOND screwed. I don’t remember anything!!!</p>
<p>any good programs that u can put on a TI 83 +?</p>
<p>Well, on the MC you can’t use a calculator… and on the free response they give you all of the formulas that you need (maybe).
So I don’t see why you would need to put formulas on your calculator?</p>
<p>thats true :(</p>
<p>Haha, I have yet to start studying, since I have AP Biology, AP Physics B, and AP Physics C tmrw =(</p>
<p>Omg databox. I feel horrible for you. You will be so relieved after it’s over though.</p>
<p>Haha, yup =) Hopefully good official diagnostic test scores will correlate with good AP exam scores?</p>
<p>DataBox that’s AWFUL! That’s three exams right in a row… I can’t imagine.
Bio is a good exam though, you’ll definitely get a 5 (it’s not too hard).
Physics B however for me… is going to be EPIC FAIL.</p>
