<p>I'd say its a standard curve. The test wasn't too hard. raw score of 65-66 should give 800 as usual</p>

<p>I thought it was both radiation and convection? Kaplan had the exact question.</p>

<p>i put radiation and convection</p>

<p>I thought it was much harder than Kaplan 4 practice tests.</p>

<p>1)Why convection? I only put radiation.</p>

<p>2)Also what did you guys put for vertical and polarized light?
I put no light will come out.</p>

<p>Damn,, I had tons of problems that I wasn't sure of. Can you guys discuss
some problems so I can remember??</p>

<p>i put radiation only. princeton's review book for 1999-2000 had this exact question (worded a little differently) and said never put convection if there is no air in the room/space.</p>

<p>I put no light will come out also.</p>

<p>i put E </p>

<p>no light will come out of the 2nd one</p>

<p>does anyone know the answer the the problem with the asteroid and the spaceships?</p>

<p>o, if it said there was no air then you guys are right. lol i skimmed the question so I'm not too sure about it.</p>

<p>What about fractal patterns one?</p>

<p>i put asteroid. cause how can you measure an asteroid going 0.x the speed of light by it?</p>

<p>i put asteroid. length of something is shorter when you observe it at a speed close to the speed of light?</p>

<p>oh and yea i just guessed the radiation/convection one. oh well..</p>

<p>There was a question about efficiency and asked which of the following produced most work or heat? i forgot</p>

<p>efficiency- i put A, 1000 (most work) and 30% (least efficient)
asteroid- i put 0.8c, bc in the asteroid's frame of reference it has no length
fractal- i put E, insect</p>

<p>what did you guys put for the
I,II,III one for force in same direction as velocity, force opposite, and force perpendicular to</p>

<p>why would there be no length in the asteroid's frame of reference?</p>

<p>hmm..yea im unsure of the asteroid one also</p>

<p>I thought the asteroid question asks from which ship does it look longest? I thought it s the slowest one.because the faster u go,the shorter it seems.And also,what is the answer to " what energy does electron lose when it hits the tv screen?" i put electrical potential.
and " at which point does the wave move upward"</p>

<p>the wave one was point B i believe</p>

<p>There was a question about looking at a bird sitting on the top of cliff from underwater. Was it the bird looked "lower" than the actual position or "higher"?</p>

<p>i put lower...but i think i m wrong</p>

<p>i put higher.....it would be lower if you looked into the water right? so wouldnt it be the opposite?</p>

<p>i dunno..</p>
