<p>what was the period(T) question? don't remember exactly..</p>

<p>I don't think period is influenced by the amplitude so therefore T would remain the same.</p>

<p>the pendulum increase in amplitude? i think it;'s the same cuase the formula for period is 2pi root(L/g).... not affected by amplitude</p>

<p>For the 2nd to the last one, was the answer 200 kg m/s?</p>

<p>I'm not sure but it was just the area of the rectangle</p>

<p>In which case it was 20. Was the Voltmeter and ammeter the second one? The one with the Voltmeter parallel and the ammeter series?</p>

<p>i thought it was 20 kg m/s. also 240 ohms, 3 volts</p>

<p>Ya, I think you're right escius about the 20.</p>

<p>And, the meter one, there was only one diagram w/ volt in parallel and ammeter in series right? If that's the case then that's correct.</p>

<p>they recycled a LOT of problems</p>

<p>what was the answer to that voltage difference question..
or current difference (not sure) where the parallel had same 2 ohms..
I think I put 0 ;</p>

<p>What was the 240 ohms the answer for? I remember 120 for some answer.</p>

<p>3 volts, and im sure its 240 ohms</p>

<p>What was the question? I can't remember.</p>

<p>This is the way I put also ! Anyone can confirm?
2. I also put the bird is above actual position.
3.” The one where there is no force is the one where the particle and the field are moving parallel. The other one that asked which would force the particle up was choice B.. I think”</p>

<p>I put with no force the one where v is parallel to the lines, the other one I don’t remember.
There was another Q I think with magnetic field and an electron..I don’t remember the answer just that you had to be careful bec of the minus sign of the electron so the F was in the opposite direction than normally with a plus charge sign.</p>

<ol>
<li>for the light bulb Q I put radiation and convection…for those of you who studied from Kaplan also there is a similar Q on test # 2 ..but with a candle..so that might be different..anyone can confirm???</li>
<li>resistance increases once metals are heated..+ R=pL/A…I think
6.At Galileo I answered “craters on Moon”…was that wrong ????
7.on an other Q I put phase shift…tho I don’t know for sure what that means…
8.I think I put insect too</li>
<li>I answered that the asteroid had the longest length.</li>
<li>anyone knows the answer to the iron ball and the water that reach termal equilibrium ?? I choose E that the termal inside the ball cant reach the water.....I know that was wrong….:( but which was the correct answer? The specific heat one.</li>
<li>the one with the 2 planes starting from same position with same speep…one vertically ..on horizontally..did u put that the horizontal seen the vertical one…on northwest???</li>
</ol>

<p>Ya, it's 240 ohms but I forgot what the 3 volts pertained to.</p>

<ol>
<li>I think it was the specific heat setting the 2 equations equal to each other: Q1 = Q2 -> mcT = McT (only difference in c, specific heat)</li>
</ol>

<p>the thin film was diffraction, anyone want to confirm?</p>

<p>1.for the "for that question with 3 pictures (I:circle, II:box, III:box)
was the answer: II, III, none?"</p>

<p>This is the way I put also ! Anyone can confirm?</p>

<p>i belive the circle works</p>

<p>Thin film = phase change</p>

<p>How would thin film go thru phase change, that doesn't make sense, so phase change.</p>

<p>other choices: diffraction, interference, reflection, refraction (all had to do with optics or slit interference patterns)</p>
