OFFICIAL SAT ii PHYSICS!

<p>I got the string and the water one right but now I'm actually not sure what I put for the diagram one.</p>

<p>i think the right answer for the two balls dropped ( one horizontally the other vertically downwards ) is v sqrt[h/g]</p>

<p>nope v√(2h/g)</p>

<p>here's the math:<br>
h=1/2gt^2
t=√(2h/g)
d=vt
d=v√(2h/g)</p>

<p>It's not that. I won't say what it is since, unlike others, I'm not so callous about the rules. But someone said it earlier.</p>

<p>EDIT: That was in reference to baphomet. And now it has been said again. :P</p>

<p>Yep. Barrons was not the right book for this test. I omitted a lot, but hopefully still got a decent score because of the curve. They asked a few pretty random things, though.</p>

<p>Yeah I got the same answer as iin77 for the prism.</p>

<p>Is it only Sound and Light waves that experience interference? Or was it the third one also?</p>

<p>All waves experience interference.</p>

<p>damn so it was only one choice for the water question?</p>

<p>Yep, they all do. I specifically remember getting a similar question wrong on a practice test, so I didnt make the same mistake twice. ;)</p>

<p>Darn. I was trying to imagine how a wave on a string would experience interference. Now that I think about it without the pressure of the test it's much more clear lol</p>

<p>Yeah for the water it's only the steam because at phase changes temperature remains the same until all of the substance has vaporized.</p>

<p>i thought the question asked about polarization, not interference</p>

<p>hey u guys are all wondering about the 'electron microscope' question, yea?
well, this is what i found:
"The electron microscope uses special lenses to focus a beam of electrons rather than light. Two types of electron lenses are used in electron microscopes: electrostatic and electromagnetic. They create electric and electromagnetic fields to both concentrate and move the beam of electrons."</p>

<p>Now does this confirm that the answer WAS lens?</p>

<p>btw, who can remember the question wordings and answers to the 3 graphs with the net work done done to the charges?</p>

<p>and im sooo nervous. this test was HARD. they better make the curve lenient.
Could anyone confirm the answer to the first few questions (PE and KE stuff) on the test? I know you might think it was easy, but I'm feeling that I might have gotten them wrong. Also, could anyone confirm the answer to the 'how is the amplitude of the waves on the line for the in phase waves'. I put 'some smaller, some larger'. My teacher thinks it could be right....he's not sure too! haha</p>

<p>Oh man, that test was insanely hard. I thought I was well-prepared with Kaplan but that test seriously took me off guard. I think I found five questions or so I've already got wrong by reading this thread. </p>

<p>Is the boiling water one only III or was it all of them? Hopefully I can remember more questions, but I'm still trying to get over the intensity of that test. Damn.</p>

<p>could someone answer/confirm my questions posted above and on the previous page? I'm really curious and I bet you guys are all curious too, so let's solve the questions together. If anyone remembers other questions, plz post the question and answers!!!</p>

<p>This test was so horrible. I took the AP Physics B Exam in Mayand this was probably like 5x harder. :(</p>

<p>I thought the difficulty was about the same as the AP Physics B Exam. I felt okay about the test coming out, but when conferring with this site, I am now confident i got 780+! But, if i had only taken regular physics, i would have been murdered by this test. This is really AP-level work. There is no way that a regular class could have fully prepared you for this test. I had to think critically about every question, and i was taught this stuff!</p>
