<p>guys,I got 2 questions as well.it was about First law of thermodynamics-Efficiency-.</p>
<p>1)efficiency was .6 2) expel 200 J</p>
<p>Can anyone verify 6 screens and light and also the question with one coil inducing current to the right causes the other coil to induce current to the left and magnetic field to the left?</p>
<p>timmycho0408- I think 6 screens and light question is 6.screen for white light.and for another question is that at least one screen can see one light so nowhere is dark.I put E.</p>
<p>for question with coil to induce current-it was opposite and left</p>
<p>the coil question was it A or B?</p>
<p>the question a ball charged Q touching an uncharged one then both have a Q/2 charge? Can anyone confirm</p>
<p>and for the screen where one light can be seen is screen 4?</p>
<p>timmy i guess it was B</p>
<p>what did you guys say for the constant velocity of the frictionless inclined plane
and did you guys get 6 m/s for the two carts? (elastic collision)</p>
<p>EDIT: Disregard</p>
<p>I don’t really remember these:</p>
<p>3 second for ball to drop… is this different from the throwing one?
bulb question is always on…? what was the question?
change in in kinetic energy = 0…? what was the question?</p>
<p>and yea im thinking for the ball on the inclined plane, velocity is in the shape of a V.</p>
<p>What do you think a raw score of 52 would yield on this test?</p>
<p>for the ball on the hill, i put the v graph for velocity, the parabola for the displacement, and the straight line for the acceleration</p>
<p>I don’t really remember the acceleration, velocity question…
What was the given situation??</p>
<p>For the electron wave patterns, I thought it was something to do with interference (I think it might be the slit experiment, though I’m not too sure about this). I forgot the exact question and choices. I narrowed it down to magnetic field and interference, and chose the latter.</p>
<ul>
<li>there’s a question about a pendulum, increasing the mass do not change the frequency (or period)</li>
</ul>
<p>^ yeah, I think I put the slit experiment, too…</p>
<p>agh, any more thoughts on what the curve will be? haha still two more days to cancel scores…</p>
<p>what do you think a raw score of 50 will be? anyone???</p>
<p>wow there are people like this one: [How</a> big is the SAT Physics curve?](<a href=“How big is the SAT Physics curve?”>How big is the SAT Physics curve?) who got 800 when they left 7 omit and got 8 wrong…i hope this test is also like that…</p>
<p>-25 ~ 720 on the Physics.</p>
<p>3 omits, and 10 wrong.</p>
<p>What should i get for that?</p>
