<p>Until the embargo is lifted...</p>
<p>what did you think?</p>
<p>The test wasn't terrible; I managed to finish with 5 minutes left. I used Princeton Review to study, and pretty much all of the topics were covered with a few exceptions.</p>
<p>i didn’t think the test was that bad, just a couple of pretty tough questions, that took some thinking</p>
<p>I was too overwhelmed by college apps to study for SAT2.
studied right before the test for 5 hours w/ no sleep…
I seriously don’t know how I did on it</p>
<p>when are we allowed to talk about specific questions?</p>
<p>Have to wait until the stickied thread in this section says that the embargo is lifted.</p>
<p>geez…I didn’t prepare well for Physics…</p>
<p>hmm isn’t the embargo usually lifted much sooner than this?</p>
<p>EMBARGO HAS BEEN LIFTED, WOOT! </p>
<p>Just in time; I refreshed the page and it was there. I swear I was not sitting there refreshing over and over, I was just lucky, lol</p>
<p>Anyway - I’ll try to keep a list of the questions and answers people give. Please be as precise as possible with both the question and answer and give a rationale.</p>
<p>My first question (might be totally obvious…)</p>
<p>A car is driving on a road with constant velocity headed east (i think). In what direction is the net force?</p>
<p>Also, what was the answer to the question with all of the names of past experiments and the related scientists?</p>
<p>Just in general: If you remember any question, even if you don’t have a question about it, please post it for everyone :)</p>
<p>nice alright i don’t remember the first one Ashyda but i think the scientist one was Galileo and the heat engine. </p>
<p>Does any one remember the answers to the beginnig question about the particle with the smalest non-zero mass or something. I said electron</p>
<p>Also the one with the electric potential. The one that followed the circle was no work right? And the two that went into the circle was work? And the one where Y was closest to X was most work? </p>
<p>Also, what was the weight of a man when the radius of the earth was doubled?</p>
<p>And does the focal length get smaller when an object is in water?</p>
<p>Also, what stays constant as a satellite orbits earth? Just angular momentum?</p>
<p>And which standing wave was not possible?</p>
<p>haha sorry i remember much more but i’ll keep it at that for now</p>
<p>1) what stays constant as a satellite orbits earth? yes, i said angular momentum only
2) which standing wave was not possible? i said the one that had two harmonics
3) focal length get smaller when an object is in water? that’s what i said
4 )Also the one with the electric potential. The one that followed the circle was no work right? And the two that went into the circle was work? And the one where Y was closest to X was most work? yup, yup, yup!!
Also, what was the answer to the question with all of the names of past experiments and the related scientists? i said galileo and the heat energy but i think im wrong for this one</p>
<p>5) Does any one remember the answers to the beginnig question about the particle with the smalest non-zero mass or something. I said electron yup, that’s what i said too.</p>
<ul>
<li>for the last question, i chose E (that went straight for a moment and then curved down, and then continued moving in the same path)</li>
</ul>
<ul>
<li>here are some of the answers i chose (i don’t quite remember the questions…)</li>
</ul>
<p>“glass and aluminum”
“negatively charged conductor”
“satellite will not approach the earth because of its existing velocity”</p>
<p>what do u guys think the curve will be like? harsh? mediocre? lenient?</p>
<p>thanks laure327. the one with two harmonics was the one with three antinodes right? and i think for the last one i chose C bc of vector multiplication, whihc was a straight line downward and then continued it path…yours sounds right though</p>
<p>Alright i have a bunch more…</p>
<p>The idea heat engine one was it 110J or 0J? Did any one ever get the answer quark? The one with the fire, was that just convex lense? </p>
<p>For the doppler affect one, was it greater for B than A for the first one and great for A than B for the second one? </p>
<p>At t=3, was the acceleration -10m/s and the velocity 0m/s?</p>
<p>For the ones with the possible numbers at the beginning of the test (constant acc. was all 3’s) what were the other answers?</p>
<p>and laure327 i think the galileo one was right, but the one that you said negative conductor for the electroscope. Can you explain your reasoning? Only because i thought it was an insulator, that would cancel out the charge and allow the leaves to move together</p>
<p>also did you get the ratio of the velocites to be greater than one. I think the question was an object is moving and it hits another object at reat, the first object stops but the second one moves…</p>
<p>And in a collision that is not elastic, was momentum and total internal energy the same? only KE changes?</p>
<p>Sorry guys i’m just putting these questions out there so everyone can remember which ones they might have had trouble with</p>
<p>Which showed proof of an expanding universe?</p>
<p>was the weight of the man W/4?</p>
<p>Alright i think that’s all i have</p>
<p>I put galileo. I knew three of them were wrong so it was either that or the speed of light guy; I didn’t recognize his name but I was pretty sure galileo didnt do anythign with thermodynamics.</p>
<p>I put e for the last one.</p>
<p>I put mechanical energy and momentum are conserved.</p>
<p>I put a negative conductor since that was the only option with a negative charge.</p>
<p>I put electron for the lowest non-zero mass one. and I put quark for the “three of these make up a larger particle” one.</p>
<p>The one with the fire, was that just convex lense? you mean the converging lens? that’s what i chose.
For the doppler affect one, was it greater for B than A for the first one and great for A than B for the second one? i think i got the same answers as you.
At t=3, was the acceleration -10m/s and the velocity 0m/s? was that the instantaneous velocity? yup, i got the same answer.
For the ones with the possible numbers at the beginning of the test (constant acc. was all 3’s) what were the other answers? i don’t quite remember what i got… for displacement, i chose the one that had something like… 1,2,3, correct me if im wrong :)</p>
<p>well, for the conductor one, i thought since the sphere didn’t make a contact, the conductor one would be the only right answer because conductors in general have charges on the surface whereas insulators don’t.
and even the stick attached to the sphere was insulator.
here, this is what PR says about insulators: “insulators closely guard their electrons, and even extra ones that might be added. Electrons are not free to roam throughout the atomic lattice.”
but again, i might be wrong 
what did u say for that question?</p>
<p>oconnk, could u explain why you chose mechanical energy and momentum?
i said only momentum was conserved.</p>
