June 2010: Physics

<p>it was something like constantly increasing the current in the wire next to the loop, which of course is true</p>

<p>Choice I was false, choices II and III were both true.</p>

<p>Choice I doesn’t produce a changing flux.</p>

<p>e) What is the position graph of a particle with constant acceleration?</p>

<p>answr: Quadratic.</p>

<p>f) What is the same for all isotopes of (atom)?</p>

<p>answr: Mass-to-charge ratio? Can’t remember if atomic number was one of the answer choices.</p>

<p>I think the answer to that one may have been nuclear charge.</p>

<p>Yes, NYEM is correct.</p>

<p>“beta particle emission question: nuclear mass stays the same”</p>

<p>I thought the answer was that energy was not conserved. Whenever there’s decay of beta, alpha, or positron, gamma rays are produced. This accounts for the slight decrease in mass(mass defect). Would this not be correct?</p>

<p>Energy is always conserved, so that can’t be the answer.</p>

<p>I think that the answer is that another particle is emitted, because momentum is a vector quantity, blah blah blah.</p>

<p>So far only -3</p>

<p>llol for me like -6 or 7</p>

<p>@ Fishfood
I got lucky on the permanent magnet ones, and one the sound ones at the beginning.</p>

<p>Ehy guys! I’ve bought SAT II Barrons Physics and I’m going to study for this exam.
I want to know If I should know Trigonometry in order to excel in this test, shouldn’t I?</p>

<p>Uhh yes, you have to know trigonometry.</p>

<p>scores coming on the 24th of june! (for june 2010 takers)</p>

<p>5 Days already? Time flies by fast.</p>

<p>like 16 hrs now lol</p>

<p>Predicted -4, got an 800 **** yeah boy.</p>

<p>790 with -10? iuno ahaha</p>

<p>wow…I should of gave physics more time to study for.
Got a 740
and a 710 on World History…</p>

<p>-13 wrong is still an 800.</p>

<p>how’d you figure out u got 13 wrong</p>
