<p>ok so like other APs and SAT IIs, this is a thread based on just questions....you post a question that you think is challenging and the person who answers it posts the next question....lets keep this thread going because not many threads are available on the subject of physics....ok so here we go</p>
<p>What is the least size that a mirror should be that it allows you to see your whole body? (not a specific #, answer is relative to height)</p>
<p>H/2
What are Newton's rings caused by?</p>
<p>constructive and destructive interference</p>
<p>What is 0 Kelvin not possible in this universe?</p>
<p>Sorry to interrupt, but would you recommend this SAT II test after an intensive summer course in Physics B? B only, not C? Is that sufficient, does it help at all?</p>
<p>cmon guys we need to prepare</p>
<p>well, wat u mean "wat is 0 K not possible in this universe", 0 K is just not possible to reach which is -273 C.</p>
<p>sorry WHY is 0 kelvin an unreachable temperature point?</p>
<p>Physics B is the best preparation for SAT II. Physics C covers either Mechanics, Electricity, or Magnetism. It does not touch on wave/optics, thermodynamics, quantum stuff, etc. </p>
<p>it is impossible to reach 0K because there would be no movement at all which is impossible to do here on earth. a chem person would be able to explain it.</p>
<p>OMG, I just finished reviewing about Magnetic field/force stuff and it's so hard! So hmm, if 2 wires carrying the same current in the opposite directions then what would be the directions of the magnetic force acting on each other? </p>
<p>p.s. will the SATII physics have lots of questions on Magnetic and eletric field/force?</p>
<p>The wires will repel each other. Know your right hand rules.</p>
<p>I can't really remember since i took this two years ago... but I think a greater portion will be on mechanics-related things.</p>
<p>guys keep it going! </p>
<p>What happens to a stream of alpha particles that is shot at a thin sheet of gold foil?
(A) All of the particles pass straight through
(B) A few of the particles bounce back at 180º
(C) All of the particles bounce back at 180º
(D) Most of the particles are absorbed by the foil
(E) None of the particles are deflected by more than 45º</p>
<p>B -- the foundamental (sp?) outcome of Rutherford's experiment.</p>
<p>Which of the following would cause an immediate change in a Geiger counter?
A) U-235
B) Bright tunsten wire
C) He-8
D) Sound emitter
E) Monochromatic light at a wavelength of 10 angstrons</p>
