<p>So what did you think? I thought it was fair. Some questions were confusing and some were really easy. There were only one or two about history.</p>
<p>hmm... I got a 780 and 790 on my last two Barron's test and I had heard that Barron's over-prepares, so I was surprised as a lot of the questions left me confused.</p>
<p>Maybe I should retake... although I guess the new score won't get to my ED school on time. :(</p>
<p>I didn't really use a company book. I jut used my class notes a lot and tried to learn the concepts more than anything. Don't worry, you probably did well if you got those scores on the barrons tests. Every physics SAT II has something that is bound to confuse you.</p>
<p>Barron's book sucks. I got a 720 on the Barron's practice test but an 800 on the College Board's practice test.</p>
<p>i did really bad i didnt really study for the test and i went to bed at 3 the night before... i so ran out out of time so i just put down random answers...</p>
<p>Physics is the hardest test i took today. hoping a 700-800.</p>
<p>too much time pressure =/</p>
<p>How about we discuss actual questions like the posters on this website have been doing for tle last several years...</p>
<ol>
<li><p>Do you just add the tension of the rope and the vertical force for that flying kite thing to get the net force?</p></li>
<li><p>Is interference why some waves that pass through slits are shorter than others?</p></li>
<li><p>Was 6.0 the answer to that lens question which asked about the penny and an object?</p></li>
<li><p>Is a change in wavelength responsible for some tunes/pitches being louder than others?</p></li>
</ol>
<p>There Are Some People Haven;t Take The Test Yet. Stop Posting Questions</p>
<ol>
<li><p>for the rope i just added even though i MOST CERTAINLY know that was not how you do it but I ran out of time and that was my nest guess.</p></li>
<li><p>Yes I put interference and I am 99% sure.</p></li>
<li><p>Yes 6. Use the equation size of object/size of image = distance of object from lens/distance of image for lens</p></li>
<li><p>NO wavelength was not it. It was amplitude because that is the energy. Frequency = pitch so that couldnt have been it. And the other choices were ridiculus. It couldve been the wavelength of the string of the object but that wasnt the question.</p></li>
</ol>
<p>What was the answer to the question about the 11th question? Well idk what the question # was but it said that there is a coil and magnetic field into the page and it gave three diagrams and asked which of the three induce current. I got all three because when I used the right hand rule, current was induced in all three. But my logic said no for one of them. I put choice (E) I, II, III but idk if it was right</p>
<p>for the kite problem you use the pythagorean theorem, 5-12-13 triangle. 500N.
interference
6
amplitude affects loudness
I put I and II only because for III the wire was parallel to the field not perpendicular, so you get sin 0 = 0 and you have no current induced. </p>
<p>what did you guys get for the galvanometer one?
and for the "expansion of the galaxy" one?
and for the "earth orbiting the sun" one?
and also for the second to last one, which point had the strongest field aroudn it? that was really weird.
for the last one, the electron moved down, right?</p>
<p>the galvanometer was you can't move it anyway to not affect the current because all the choices had up or down as an answer and had current changing or being constant...so it had to be the choice with no movement and contant current</p>
<p>the expansion of the gallery was I and II - the redshift and the radiation i think I'm not too sure about it. The orbiting was definetly not an answer but idk about the radiation.</p>
<p>earth orbiting the sun I dont remember.
I thought it was D because it was closest to the middle and equation of magnetic field is B = constant Current/distance So as distance increases the magnetic field increases. </p>
<p>What did you guys get for the graph of A vs B^2? To make it a straigt life you have to make it A vs. B^2 rite? instead of A v. B because that would be a parabola. and same for others</p>
<p>maybe i misread the question but i said you need to take the square root of B. I went the other way.</p>
<p>and yay, I put D for the magnetic field one.</p>
<p>"for the last one, the electron moved down, right?"
It was an electron? Oh crap... I put up because I treated it as a positive charge. :(</p>
<p><i>maybe i misread the question but i said you need to take the square root of B. I went the other way.</i>
It said the "square of B." That means B^2... I made that same mistake on a practice test.</p>
<p>hmm... and since ppl are asking qs:</p>
<ol>
<li><p>What was the q involving eV?</p></li>
<li><p>How does heat relate to resistance? (circuit problem)</p></li>
<li><p>The guitar string thing with the two anti-nodes... was it the last choice?</p></li>
<li><p>Yellow light is shown on a metal and electrons are released. Then, green light is shown. What changes? Frequency and max KE?</p></li>
</ol>
<p>i said that the p = v^2/R so the more resistance you have the less heat because the more power you have the more heat you have. so it was like... double the one for the 20ohm resistor? </p>
<p>frequency changes for sure, not sure if max KE changes</p>
<p>yup, A vs. B^2</p>
<p>and H was h/2, since the power = work/time, so work = power<em>time, and since we know power = I^2R, then work (heat) = I^2</em>R*t</p>
<p>t is the same, I is the same (series connection), R is halved, so it's h/2</p>
