<p>I felt like that test had an unusual amount of tricky-style questions (like the downward acceleration and downward net force)</p>
<p>Hey guys lets make a consolidated list</p>
<p>thanks testtaker2, i understand my error now.
do you guys think -16=800 or will it be harsher?</p>
<p>posting consolidated in a bit…</p>
<ol>
<li>A (acceleration and net force - both negative)</li>
<li>A (acceleration and net force - both negative)</li>
<li>A (acceleration and net force - both negative)</li>
<li>Two stationary net charges - no points had 0 force</li>
<li>Two stationary net charges - outside points on x-axis deflected to the right</li>
<li>Standing waves - highest amplitude (obvious)</li>
<li>Standing waves - lowest frequency (top one of this picture <a href=“http://img.ultimate-guitar.com/_img/.../zeg/3-4-1.jpg[/url]”>http://img.ultimate-guitar.com/_img/.../zeg/3-4-1.jpg</a>)</li>
<li>Standing waves - largest wavelength (top one of this picture <a href=“http://img.ultimate-guitar.com/_img/.../zeg/3-4-1.jpg[/url]”>http://img.ultimate-guitar.com/_img/.../zeg/3-4-1.jpg</a>)</li>
<li>Charged particle repelled from wire (3 question set)</li>
<li>Two wires with current in same direction attract (3 question set)</li>
<li>Charge deflected parallel (3 question set)</li>
<li>Largest change in momentum = straight line graph with largest area under “curve”</li>
<li>asteroid would appear to have the greatest length at the asteroid itself</li>
<li>Galileo didn’t discover expanding universe </li>
<li>Superconductivity = low temperature electronic devices</li>
<li>Light bulb only gave off radiation</li>
<li>Convex mirror produced the virtual image (image was behind mirror and smaller)</li>
<li>Image formed at 15 cm on other side of convex lens.</li>
<li>Image of child was 10.5m from adult (real adult not image)</li>
<li>If the switch were closed the bulb NOT in the parallel would have the greatest current</li>
<li>The consensus is that all 3 brightness would change if the switch would close because resistance discrepancies</li>
<li>Curved acceleration-time graph - increasing speed until constant speed </li>
<li>Resistors are affected by length, area, and temperature</li>
<li>Change in internal energy = -12J</li>
<li>Total kinetic energy of ball being dropped = 120J</li>
<li>question 74: direction cannot be found because magnetic field direction is not known</li>
<li>last question: alternating loud, soft (changing intensity)</li>
<li>average speed of the snail 2m/hr</li>
<li>magnitude of electric field = V/d</li>
<li>slope of graph = .33ohms</li>
<li>16 decays per second
32 None of the above affected radioactivity of an element</li>
<li>Atom loses energy when emitting photon</li>
<li>amount of time doesn’t affect the heat i think Q=mc(delta)T</li>
<li>smaller hole and larger wavelength would make single slit diffraction larger</li>
<li>time objects were in contact 0.1s</li>
<li>the force on object makes it go in a circle</li>
<li>linear expansion? 10.006</li>
<li>2 photons? need confirmation</li>
<li>doppler effect = two objects moving relative to each other
42 inducing electric field moving the coil and wire</li>
<li>increasing speed equals increased kinetic energy (pendulum)</li>
<li>force acting against pendulum = decreased kinetic energy, increased potential energy?</li>
<li>voltmeter connected in parallel, ammeter connected in series</li>
<li>piston moving down, heat added </li>
<li>the difference between the two pitch forks – was this wavelength?</li>
<li>something about wavelength becoming shorter when entering water, can’t remember the question. there was a ray diagram.<br></li>
<li>accuracy was +/-0.1mm only (debate with +/-0.2mm as well –> need confirmation)</li>
<li>accuracy of ruler, 25 +/-0.2 (does this look familiar?)</li>
</ol>

<ol>
<li>force acting on pendulum, both max KE and PE decrease.</li>
<li>yah i got 2 photons.</li>
</ol>
<p>Unrelated to SAT Physics (I took it in May) but if anyone could answer this it would be great.</p>
<p>Which direction does a compass point when it is near
to a wire conducting electricity?
(a) north
(b) directly toward the wire
(c) directly away from the wire
(d) none of the above</p>
<p>I thought it was d, because it would follow the magnetic field lines? Does a wire produce magnetic field lines as a north/south magnet does, it does it produce circular field lines? In that case, would it still be d?</p>
<p>well, you can just use the right hand rule…so yes, D.</p>
<p>Heygirl: can you remember if the photon question letter answer was A by any chance?</p>
<p>Can someone describe the asteroid question in more detail?</p>
<p><a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides;
<p>^ Explanation of the concept of length dilation.</p>
<p><a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides;
<p>^ Formula for length dilation.</p>
<p>If you look at the formula and put two and two together, you’ll find the reason why the answer was where v = 0.</p>
<p>the answer to the complied list #44 should be decreased in both KE and PE. since the position lowers and speed decreases</p>
<p>^yup! I’ll get it with an update next time.</p>
<p>Looking at a retake in october…</p>
<p>Hmm, what was the pitching fork question? Does anyone remember?</p>
<p>And so can someone explain why ±.2mm is also as accurate? I’m not sure why…</p>
<p>the pitching fork question dealt with two different pitching forks with two different frequencies. The question was which of the following is the same.</p>
<p>Two different pitching forks with two different frequencies, the speed of the waves would be the same, right?</p>
<p>I think the answer to that was actually velocity because they were in the same medium. And 0.1+/- is the more accurate because it provides a smaller range.</p>
<p>i agree with chrisma, they should both decrease</p>
<p>^yes we established that. All of these will be updated in the next list :)</p>
<p>what were the two sigfig questions? i know one of them was the ruler (was that 25 plus/minus 0.01 or 0.2 or whatever?) and what was the other one?</p>
<p>any ideas on the curve?</p>
<p>Is -13 wrong (raw score of 59) really a 800 on the physics test, if anyone has any knowledge. Maybe -10 wrong (raw score of 62) is a 800?</p>
