<p>How did the Test go for you guys? I skipped around 10 question and for now have 2 questions wrong. Hope I get less than 3 wrong for the rest for an 800.</p>
<p>That’s impossible man, a minimum of 70 raw usually result in a 800. Anything below that is very unlikely, not to rain on your parade but you can say bye bye to your 800. I guess 720 is your minimum score. Hope this helps. :D</p>
<p>****, it was impossible. It was soooooo hard… I skipped 3 and was unsure about a lot of them.
@Wilsoncw No - raw score of 63+ is an 800. The curve is huge. Although, that score is still less than 800.</p>
<p>I think I got messed up with 2C. Idk</p>
<p>Did you get a bunch of Cs? Anyone?</p>
<p>All the questions I can remember:
Circuit problem - which had the most current flowing through it?
Problem where planet orbits around the sun
momentum of balls
kinetic energy of balls
cause of the sun being red at sunset
electromagnetic wave and sound wave have the same frequency, which has the larger wavelength
how many possible emissions of the hydrogen</p>
<p>I’ll add more later</p>
<p>It was so freaking hard, ridiculous. This test better have a higher curve.</p>
<p>question on no contribution to thermodynamics - snell
amu question - not sure
question on what is same across all carbons- nuclear charge
question on sun color in atmosphere- scattering
pretty sure one answer was refraction or something like that in that same part ^</p>

"</p>
<p>1) the electromegnateic wave question had them all having the same wavelenght, we had to figure out the frequency. I believe that the electromagnetic had the higher freq
2) kinetic energy was conserved across all 3, not sure about momentum
3) no clue on emissions
4) i believe r3 or whatever R was all alone had the most current because the rest all added up to equal that one
5) satellite with radius of R and mass of 2m had the highest force, pretty sure it had teh highest kinetic energy as well</p>
<p>i’ll try and think of more answers that i had/questions, but this test sucked.
pretty sure i got at least 10 wrong -.- there goes that 800</p>

why does a strip made of two metals bend when heat is applied?</p>
<p>I’ll add more later</p>
<p>@tips1160:
carbon was nuclear charge, sun color was scattering</p>
<p>@bojl95 woops yeah you’re right, too late to edit the post now
carnot efficiency question was .4 or 40%
and the 2nd question on velocity/ acceleration was 0 velocity/downward acceleration at the top</p>
<p>there were also a few questions on graphs related to the equation V=IR,
the first answer to that section was Ohm’s law I believe
there was one graph where it should have been a positive sloping linear relationship with a smaller slope than the given graph</p>
<p>there was a centripetal motion question that was pretty straightforward</p>
<p>edit: to the op: not to be a buzz kill, but 10 wrong is automatically a 790, 15 a 760 ect, I’m already at like 6 wrong :c</p>
<p>What was the answer to the one about properties of electrons? I put that they can cause interference. </p>
<p>And with the slit diffraction question, do both the central fringe width and the width between bands increase when the slit width is decreased?</p>
<p>I said that both of them increased ^ and in regards to the electron question, wasn’t it what they cannot do?</p>
<p>I got the fringe width stays the same because the wavelength is the same, but the width between the bands increases. Not certain though</p>
<p>I think it asked what is true of electrons, because some of the wrong answer choices were like “an electron has zero mass at rest”</p>
<p>Efficiency is 40 percent, sir.</p>
<p>For the circuit that has a battery and a capacitor with a switch:
-When switch is at A, it stays on?
-When switch is at B, it starts bright then gets dimmer?</p>
<p>Oh okay yea you’re right, i think i confused two questions there,
and the fringe width does go up, i’m not sure about the distance between the fringes
also did you guys say that the proton goes to R or between Q and R?</p>
<p>No. It is either dim or off…</p>
<p>Capacitor hogs off the electrons and acts as a barrier… I marked off because it said “after a long time” o something like that</p>
<p>For the efficiency question, was the cool reservoir 300K or 200K?</p>
