<p>i meant the deflecting after moving into a uniform electric field going into the page. it was either upwards or downwards...</p>
<p>yea, i must have read the question wrong... i thought it was an observer, not a guy on the spaceship</p>

i thought it was greater than c b/c it asked from the perspective of one of the people moving (the other guy was going in the opposite direction)
sp33d12-it asked for the most important observation so that would be taht some were deflected straight back.

<p>In relativistic physics, no speed can be greater than c, regardless of the frame of reference. The answer is, it's greater than .6c, but less than c. Tell me if you're interested in the calculation.</p>
<p>was entropy an answer to any of them? something about masses of different temperature put together in an isolated place and what would happen to them</p>
<p>there are a question using E=hf and something about some value doubling. it was the frequency doubling, right?</p>
<p>yea, what was the answer to the question with the masses put together?</p>
<p>some choices were: lower/higher enthropy, internal energy zero</p>
<p>oh... entropy of the system always increases....... 2nd law of thermodynamics</p>
<p>ok, and there was some other question about the boiling point of something
any of you remember that one?</p>
<p>and one more about a plane mirrow and what's on the same side of it or something like that: incident ray, normal and mirror was one of the answers i think</p>
<p>The answer to the Rutherford one was (I'm nearly sure) that some of the particles went straight back which showed that all the positive charge is a tiny, dense nucleus in the center.</p>
<p>I skipped so many questions! I didn't even count how many I skipped but at least like 12 I'm sure... Alas, I should have taken it in November so if I didn't do well I'd have a chance to take it again. :(</p>
<p>Edit: I choose the one about the entropy increasing. For the boiling point one, I said it was equal to the atmosphere pressure? I think that's wrong though. :/</p>
<p>i remember most of them, but i need more details to remember it correctly lol</p>
<p>so does anyone remember any of the two posted above??</p>
<p>How bout the one about the best insulator and the best conductor? What did you guys get for that one???</p>
<p>sneveu, yea your right, reflected particles, NOT DEFLECTED, was correct. although some are deflected in the experiment, reflected is what rutherford used to conclude that most of the matter is in the center of the atom.</p>
<p>I skipped the one about the mirror. None of the answers seemed right...</p>
<p>"sneveu, yea your right, reflected particles, NOT DEFLECTED, was correct. although some are deflected in the experiment, reflected is what rutherford used to conclude that most of the matter is in the center of the atom. "</p>
<p>Ah, that's good! At least in case it's an advantage to take the Physics test while I'm taking Chemistry. (I didn't think I'd learned enough in Chemistry yet to take the Chemistry.)</p>
<p>For the insulator and conductor, I said the silk and glass just because I remember doing an experiment with those two things in class. I was thinking perhaps aluminum and glass, but aluminum is a semimetal and therefore perhaps not a good conductor?</p>
<p>oh boy. what did you put for the insulator/conducter question? i think i put the last choice</p>
<p>ok three questions from the test:</p>
<p>1)there was some other question about the boiling point of something
any of you remember that one?</p>
<p>2)one more about a plane mirror and what's on the same side of it or something like that: incident ray, normal and mirror was one of the answers i think</p>
<p>3)how does the diameter of a coin change (its image)? i think i got 6 (i just used the magnification)</p>
<p>mirror? it was the one directly on the opposite side of the mirror from the object, good ol' princeton review hehe i am pretty optimistic about this test</p>
<p>1.) it was vapor pressure=atmospheric pressurre</p>
<p>no, the other question about the mirror, it was one of the first 20 questions or so, not the other one, the second one was easy</p>
<p>1.) dont remember the question
2.) answer is incident ray, normal ray, and the third ray (dont remember what they called it), the mirror isnt in the same plane as the others
3.) i put 6.. i hope its right</p>
