<p>@skepticidal: I put inc freq and speed I think for the first part and period for the second part? and I also said virtual reduced. No. Wait. I don’t remember. I’m pretty sure I put that. My friend says virtual magnified, but idk if I believe him.</p>
<ol>
<li><p>I said that when weight was added, speed changed. (Did it ask for what went up, or what changed?) Because of mv^2/r = mg. The right side doesn’t change, so only pay attention to the left side: If m increases, v must decrease.</p></li>
<li><p>Since g is constant and m on the right side increases, the value on the left must also increase. So I said v increase . . . or radius decreased. </p></li>
</ol>
<p>That was my thought process, not sure of my actual answers. What were the options?</p>
<p>edit// WAIT WHAT. There were options that said “frequency AND speed” changed?! </p>
<p>I also put virtual magnified. I’m pretty sure it’s right.</p>
<p>yeah D was like I and III</p>
<p>@Abrayo: it was what happens when the weight of the weights (mg) changed. Then it asked what happens when the weight of the ball changes. Also, I put virtual magnified.</p>
<p>Uh oh. . .
I don’t remember that.
I know I used v = 2pirf for one of the questions on the test.
Maybe it was this one and so I did speed&frequency changed. I hope so.
Were there any other questions that would have required the use of v = 2pirf?</p>
<p>…not changed, increased!</p>
<p>haha.</p>
<p>and wait was it convex or concave?</p>
<p>Oh yes, increased, sorry.</p>
<p>I hope it was a convex lens . . . or a concave mirror.</p>
<p>Ok so the one that had focal length 10, that was 30 right?</p>
<p>Yes it was 30</p>
<p>can we make a compiled list?</p>
<p>K good I didn’t totally screw up lens/mirrors ha. What was the quasar one?</p>
<p>What were the givens? 10 focal length and 20 distance or something? Or 15 focal and 10 distance?</p>
<p>I thought the quasers were really easy . . . unless I messed them up.
The first one, for which combination could be -1, was one of each, because adding one of each would be 0+0+(-1).
I forget the second one.</p>
<p>Hey every1 lets try to gather up the tough questions …</p>
<p>Can any1 remember the resistors question? switch s2 and s4 or sumthng was closed …
Any idea about the raw score marks?? does it drop if many students fail to get good raw scores? …</p>
<p>i thought of rmv = rmv so if m incresaed, then v would decrease, meaning T would increase… ??</p>
<p>can we also make curve predictions, ik blue book says 59/75 i thought this was exceptionally difficult it’d say 57 = 800, 42 = 700, 28 = 600? am i not thinkin about this correctly? todays was a lot more theory than math, and the math on it was arbitrary rather than really relevant</p>
<p>acdf or adef or something like for the resistors?</p>
<p>all i remember was the quark was -2, and the distance btwn the trees was 90, newton was based off galileo… hmmm</p>
<p>I think I got acdf for the resistors.</p>
<p>Your rmv=rmv thing scares me though . . . which is the correct answer?!</p>
<p>how about the resistor problem…</p>
<p>did you guys say bulb D, the one in series with the parallel portion was brighter or dimmer? i forgot how to figure that out >.></p>
<p>resistors were adef, there was no c, curve predictions? doesnt the average always have to b lke 660 for physics?</p>
