<p>4 d planes move up and right(as viewed from the top)…wats d direction of the velocity of A relative to plane B. izit northwest(my pick) or northeast…</p>
<p>^ northwest</p>
<p>is anybody able to make a compilation of the questions? thanks
i have no clue how many i omitted but it just seemed that i could have gotten the answer if i knew how to pace.</p>
<p>wow… was this test hard? or medium/easy??
I omitted like 10 and guessed like 5</p>
<p>guys, the bird one was 100% higher, I’m sure. Draw a diagram! If you extend the refracted ray seen by the diver into air, the bird is higher since the ray is refracted towards the normal</p>
<p>nvm…</p>
<p>Oh and I also got 0.025</p>
<p>Was the fractal question the body of an insect?</p>
<p>Moonlitexpress, same here! I sped through the last ten questions cuz I ran out of time so I couldn’t really think about them… Luckily they were concept questions though. The only real calculation question I got wrong cuzit took me so long to calculate so I just guessed… Could have definitely got it rich with more time</p>
<p>Oh, one last question. There was a question that showed two plates and (I think) an electron moving through it and it asked to describe the motion of the electron as it enters between the two charged plates.</p>
<p>I was not sure whether it moved up with a circular path or a hyperbolic path… First I thought circular because that’s how they show the motion of an electron to be in a uniform magnetic field, but then I thought that since it was between two plates it was hyperbolic…</p>
<p>I think its a parabolic path. It’s an electric field, not magnetic.</p>
<p>Ah yes, true. Well, despite that misunderstanding of mine, I might have luckily gotten it right. Fortunately I remembered a few electric field diagrams involving parabolic paths.</p>
<p>haha nice~~ I know I’ve definitely gotten 4 or 5 wrong, and 2 omit…Hoping for 800…</p>
<p>Yay, I’ve been getting a good amount of them right.</p>
<p>The question about helium nucleus -> alpha particle?
The question about question about sound waves and electromagnetic waves-> that waves in the same medium move at the same speed or something like that?
The internal heat question-> 2.5 i think? work was added to the system, not done by the system, so W had to be positive?</p>
<p>anything else you guys had trouble with?</p>
<p>lol the helium nucleus question was very self-explanatory if you just knew that the charges and mass had to be equal on both sides
dont remember the answer though</p>
<p>MegaVortex7: Performing work on a system means increasing the internal energy.</p>
<p>nick 321: i know, so that means that you had to add the two quantities together, right?</p>
<p>there was a wave diagram question on which point shows 2T (2 periods)? i think i put E which was 2 wavelengths…</p>
<p>and for the vertical component of velocity in a projectile motion, i think there was a question on what the graph looks like versus time and i picked one that shows an upward curve, not linear</p>
<p>vertical component is linear i thought? vertical acceleration is constant, so the slope has to be constant</p>
<p>I don’t even know how I feel about this test…I ran out of time like most of you guys, and that rarely happens to me…and even though I took AP physics B 2 yrs ago and AP Physics C last yr I almost had a breakdown during the test…I couldn’t figure stuff out. I definately like the math part better than the consept, and hate the part of no calculator allowed</p>
