<p>For the question with the rods, did anyone get up and at rest??</p>
<p>Pretty sure it was 10,000 instead of 1,000. Because the guy was 10 m high, weighed like 100 kg, and then g = 10. PE = mgh, so KE = 10,000 also.</p>
<p>And for the resistors, P also equal (V^2)/R. But I actually might be wrong. Did anyone else get 3 ohms?</p>
<p>Do you guys remember the problem about the light going into glass which was 4/3 = n.</p>
<p>My answer was something like 3lambda/4</p>
<p>Do you guys remember the questions from the beginning? I remember them being sort of hard.</p>
<p>ALso, the one about average velocity on that graph. Was it like 1/15 for one of them and the 0 for average velocity, cause displacement was 0</p>
<p>It didn’t ask kinetic energy at ground level, it was some point in the air I think</p>
<p>I got 5g for the astronauts.
For the man one I did the same.
For the power I got 12 ohm.
The orbitals was momentum/velocity.
What did you guys did for the continuous , dark and bright spectrum for the bulb?
Was the answer A)?
And for the electron cloud was the answer d) The bohr model of the atom?
Plancks constant lamda was=hc/E
For the transverse waves I did up and down.
KE was 10,000.
Units was watts.
I did E for ray traces.
Force exerted back was F and the greatest charge was +2q and -2q.
I got one 3lambda/4 also on the index of refraction question.
For the graph one I got average speed to be 1/5 and 0 for avg velocity.
I think for the KE they asked to find the energy of the box JUST before it hits the ground. I think its the same as mgh=10000.
I don’t think I did well.
I hope the curve is big.</p>
<p>For the astronauts I did
R-mg=ma (R=reaction force from the surface of the ship to the man)
5mg-mg=ma (ma is the net force acting on him)
4mg=ma
4g=a
Darn I got 4g but I filled in the bubble for 5g!
But I guess the answer is 4g.</p>
<p>What do you think the curve would be?
I think that the test was very hard.
I got like 9 questions wrong and I left 1 till now. Might increase when I see the rest of the answers.<br>
I had prepared well and was hoping for a 800.
Gosh I am so upset.</p>
<p>What were the other options for orbitals? I remember thinking about electrons’ wave nature, was that one of the answer choices?</p>
<p>Yeah I did the same.</p>
<p>So what do you guys think the curve will be? I think the difficulty of the test was similar to the ones in the PR book, which I always miss 5+ with 4-6 omitted…</p>
<p>The unit question: (kg.m/s2 . m)/s =N. m/s = J
I think so</p>
<p>Do you guys find the test is … ? </p>
<p>1)easy
2)medium
3)hard
4)very hard</p>
<p>Just want to check the curves</p>
<p>I think that this test was harder than the ones given in PR or Sparknotes. The questions in PR had more mechanics but this test was full of waves! I hope the that the curve is big enough. I did about 9 or 10 wrong and left 1.
The test in the official book was very easy compared to the actual one!
How did you do?</p>
<p>Yes there are full of waves! This is my first time taking it so i didnt do that well i omitted 26 questions and some of my answers were wrong. I need to get more than 600! please collegeboard give us a nice curve!!! :(</p>
<p>For the two magnetism/current questions did you guys get goes into the paper, and goes to the right for the other one?</p>
<p>Is anyone canceling their scores? :(</p>
<p>I thought it was easier than both the October and November tests, but still very hard. I just really want to get at least a 700 and I will be ecstatic, and this is my last chance and all since I’m a senior.</p>
<p>Its to the left. Also for astronaut, he is feeling 4Mg pushing up so the net force equation is 4Mg-Mg=Ma, so its 3g, not 4g</p>
<p>Oh and the other question was out of the page</p>
<p>Yeah out of the page is what i meant. there was no option for into the page</p>
<p>And why was it to the left?</p>
