<p>at the newton question, it was galileo, right?</p>
<p>JOHN M
the beam question
three beams: one went straight, two were deflected (to left and to right) which of the statements is true?
beam 3 contained electrons or photons, beam 1 (neutrons or proton), and beam 2 i dont remember.</p>
<p>Elisa what was the answer then to the snells law question with sin theta? I think I got that wrong. was it a choice with a denominator value or no? (i put E)</p>
<p>anyone can remember the question about the adiabatic problem, problem involving heat and internal energy?</p>
<p>hey, I am taking physics now, and im going to take AP next year, do you recommend taking SAT physics after the AP class?</p>
<p>Well, that’s the prime time to take SAT II physics. If you’re taking the physics C exams, you will have to study a few topics independently. I’ve heard physics B is the best preparation for the SAT II.</p>
<p>Skings,
The snell law one I don’t remember the answer …sorry… I solved it with the calculator… don’t tell my proctor 
The adiabatic one was confusing…I don’t remember which I put! The internal energy increases if work is done by the sistem but in the same time the system lost heat…so I don’t know… Any toughts on this one Jman?</p>
<p>My physics class briefly touched on thermodynamics, so I did not remember what an adiabatic system entailed. I do not remember what I put.</p>
<p>Adiabatic Question</p>
<p>An adiabatic process is one with no heat exchange. In an adiabatic process, volume, pressure, internal energy can all change, but Q=0 always. I can’t remember the question, though.</p>
<p>Question: 3 beams</p>
<p>The one with the electron was the true one, I think. But I think you are rephrasing the question wrong. I don’t remember anything about electron or photon… Just electrons. But, of course, it could be my memory that is failing here.</p>
<p>
</p>
<p>You ■■■■■■■! Anyone could have gotten that with a calculator! :)</p>
<p>johnM, What textbook would you recommend for AP Physics B? I am currently using GIANCOLI’s Physics: Principles with Applications 5th Revised Edition. Seriously, this is a long and hard book to understand. It is very difficult, that is why I don’t read it at all.</p>

<p>I can’t help you there. I’m not really familiar with the AP system. But I’m sure whatever Princeton Review has to offer should be good.</p>
<p>I doubt your book is that bad… You probably just need a second book to contrast and compare with (two books are always better than one). I would mention the Halliday/Resnick/Walker text. But it is calculus based, so it might discourage you even more.</p>
<p>Wait, responding to some earlier messages, you can’t get 50 wrong and get a 600, you have it backwards. You need 50 right to get a 600.</p>
<p>did your mother hit you on your head when you were a baby
getting 50 right at worst will get you a raw score of 43, which will get you at least 680
thx4trying tho</p>
<p>lol these people already took the test by now
they dont give a f**k anymore</p>
