<p>1/2 questions were out there but on the whole I felt it was pretty moderate in its level of difficulty.</p>
<p>I found it to be quite easy actually. Definitely easier than the PR practice tests i took.</p>
<p>Can we discuss answers?</p>
<p>i think. did you all finish?</p>
<p>YEah but skipped like 7-8</p>
<p>skipped 14…</p>
<p>skipped 4 but guessed on quite a few more. does an incandescent lightbulb store energy?
and does air resistance slow down speed or acceleration?
once air resistance=acceleration, what happens?
OH and the second question-- where is Kinetic Energy the greatest? PE was at the highest point, right?</p>
<p>2.1 I think</p>
<p>I actually thought this was harder than average. I took about 12 practice tests and found that this one asked some harder questions early on and had what seemed like trick questions. Hopefully its a nice curve and i got an 800!</p>
<p>Agh at hardly no mechanics. Optics and waves annoy me…I would’ve rather they replaced it with something most consider equally difficult-some rotational motion or projectile. Sigh.</p>
<p>I ended up skipping 8, so I have a chance at an 800 depending on the accuracy of my other answers. We’ll see how that goes.</p>
<p>whats the best curve you all have seen on this?</p>
<p>on CB’s released exam -16 RAW points was an 800</p>
<p>i thought the test was a little hard–i did 3 sparknotes tests which i found easier and barrons was really hard</p>
<p>wat questions do people remember im trying to see how i did</p>
<p>anybody know wat the answers were to the two questions where there was a charge +Q and +q and there was a path from x to y. it asked which path had the max net work and which had 0 net work</p>
<p>Electric fields are constant around a given circle, and decreasing in strength as they radiate outwards. So, the one where y was towards the center took the most work, and the other two take no work as it’s just moving around a level of constant electric potential.</p>
<p>^But a force is still required to move the test particle.</p>
<p>and the tangential velocity is perpendicular to the force, so there’s no work</p>
<p>^That’s what I was thinking.</p>
<p>i guess we’re on the same wavelength then
=P</p>
<p>hated the wave and frequency questions.</p>
<p>there was a question about the frequency of an observer or something. I don’t remember it exactly. the frequency would be greater as it approaches and lesser as it recedes, correct?</p>
