<p>any more questions you guys remeber? i am still not sure wheter to cancel my score or not…</p>
<p>There was this relativity question about observing a rocket from Earth and something.</p>
<p>Length of time and length of rocket? Also, what made a star look lower from the horizon from Earth or something like htat.</p>
<p>^refraction due to bending of the atmospheric gases, and shorter length/more time for relativity</p>
<p>I think I put that…</p>
<p>Nice.</p>
<p>I remember there were 2 choices I debated between for the relativity question, shorter length/more time, and ____ length/more time. Which was the second question, in respect to length?</p>
<p>one question near the question about “what made a star look lower from the horizon from Earth or something like htat”… was “dampening” the answer for that?
i put refraction for “what made a star look lower from the horizon from Earth or something like htat”</p>
<p>the question on the inverse relation…the choices were intensity of light, g force, and time in projectile motion… i put g force and intensity of light (i was not sure about the light one)… i looked up online([Calculating</a> delta R from light intensity of M31](<a href=“Imagine the Universe!”>Imagine the Universe!)) and i was correct for the light one…so the answer is g force and intensity of light</p>
<p>^^yeah, i’m pretty sure refraction was right. i don’t remember putting down dampening for any answers.</p>
<p>and yes, the force of gravity (F=GMm/r^2) does have an inverse square relation with radius and so does the intensity of sound (I=P/r^2).</p>
<p>i mean the question right next to refraction one(“what made a star look lower from the horizon from Earth or something like htat”… ) these two questions share same answer choices.</p>
<p>And the question on the magnet moving through the solenoid… someone talked about this before but which seems to be the right answer “same direction” or “opposite direction”? i put opposite direction but i am not sososo sure</p>
<p>Yes dampening was a correct answer from the same set. It talked about sound getting quieter or something</p>
<p>@whykwon: I put opposite direction.
@Latency: Yeah, I put dampening too.</p>
<p>^muahahah i omitted the dampening question</p>
<p>Another question… there was a diagram of one person passing a ball to another person (inside a cart), and you had to find out what V and d was when the cart was moving… or smthing like that. I chose Vx and d (i think its choice C). Did anyone else do this?</p>
<p>Also what did u guys put for the magnetic field lines for the loop of current through the paper? (the last magnetism question matching section)</p>
<p>Page-D: yeah, i put vx and d also. the speed and displacement of the ball are relative to the other person so as long as the train moves with both of them there shouldn’t be a change.</p>
<p>same here…kkkk</p>
<p>I omitted that question. Lawl.</p>
<p>chem discussion thread has about 500 replies while we have about a hunred…not many people taking sat physics? i just wonder why
i need to check some answers before next monday…lol</p>
<p>Hmmm there were two questions that I wasn’t sure about:</p>
<p>Starlight near the horizon appearing lower than it actually is - isn’t this gravitational lensing? but that’s not an answer choice :(</p>
<p>Which of the following people were not involved in light/waves something - *** is a history question doing on this?.. lol</p>
<p>edit… hmmm it seems it might have been refraction 
since the index of refraction for a vacuum is different than for air…</p>
