<p>A is proportional to B squared and what graph should we look at to see a line?</p>
<p>the answer was A versus B squared right??</p>
<p>(i am second guessing myself .. lol)</p>
<p>"A is proportional to B squared and what graph should we look at to see a line?"</p>
<p>Are you sure that was the question? I remember my answer I was 1/b^2. However, maybe I misread the question.</p>

this is because the original was like this
/\/ and you cant just create another segment in a wave... i hope

<p>Remember that the original graph is just part of the whole thing. If a pic is taken at any arbitrary point of the rope at that exact one particular moment, it may show you some other segments unseen from the original graph. That said, a straight line in another section of the rope at the time can't possibly be a straight line since the wave is a standing wave.</p>
<p>im second guessing myself.... im not really sure now</p>
<p>Ah, that makes sense asbereth. I think you all were right that it was the straight line then. I remember when I had questions like this in Physics class, I would take a string (or make myself a string with a ball at the end and swing it or whatever the problem called for) and try it! I wonder if taking the shoestring out of my shoe (not that I had time but...) would have been considered an "unauthorized study aid"...</p>
<p>lol... haha iii dunno</p>
<p>there was a question about the expanding universe?</p>
<p>anyone remember it?</p>
<p>I liked that one, I think. It asked which <em>wasn't</em> proof that the universe was expanding and the choices were like background radiation, wavelength shift in light emitted from distance stars, and I forget the others. The answer that I said <em>wasn't</em> proof is that the earth orbits the sun in an elliptical orbit. The <em>wobble</em> in the elliptical orbit is what is significant.</p>
<p>i thought it said which is proof of the expanding universe</p>
<p>crap... i FREAKIN MISREAD THE QUESTION! not like it would have mattered lol.. got it wrong regardless, the only one i was sure of is the wavelength shift (is a sign)</p>
<p>edit: i thought the same thing</p>
<p>yea the answer was red shift and background radiation. got that right but i still omitted 10 and got 3 wrong. maybe i shouldn't have retaken that 730</p>
<p>For the expanding universe one there was choices I, II, III. I put I and II- not the one with the elliptical orbit. Does that sound right?? I hope so. :)</p>
<p>i think i put that too...</p>
<p>Damn it, was there a choice for I, II, and III? If there was, I put that. If there wasn't I put I and II.</p>
<p>there was but the answer is redshift and background radiation</p>
<p>Oops, I think you're right and it wasn't except. I can't remember if I explained it wrong because the way I figured it out was elimiting the eliptical orbit or if I actually read it wrong and choose the eliptical orbit. Speaking of orbits, what about that question where about the earth orbiting the sun? One of the answer choices - which I didn't choose; I can't remember what I chose - was that sun pulls more on the earth than visa versa or something like that?</p>
<p>I still think the answer to the standing wave question was...</p>
<p>/\ /\
/ \/ </p>
<p>For an instant, it could be a straight line (I think); so it's not that one.
Anyone agree with me??</p>
<p>yeah... I remember that one.</p>
<p>I put that the earth moves faster when closer to the sun, and that the sun pulls the earth more or whatever.</p>
<p>The standing wave question was the answer with two "bumps" I believe. It can be a straight line.</p>
