<p>fractals are like things you learn in geometry lol…anyway answer was the insect … E I think</p>
<p>doesn’t the thin layer of film question havereflection and refraction? Was this a I, II, and III question?</p>
<p>P.S> What were the other options for the sound waves vs. light waves quesiton?</p>
<p>P.SS> What has the least affect on horizotal motion </p>
<p>-shape of object
-vertical distance
I do not know other choices.</p>
<p>also, how many wrong for 750, a reasonable target…also what score in gneeral on SAT IIS are considered IVY material - 750 740 or 730+???</p>
<p>I think I put shape of object…but not sure if it was this question…but for the two choices you stated…shape of object would be the better choice</p>
<p>a 750 is like a raw score of 45 or 46…that is INSANELY AWESOME…that like getting 24 wrong</p>
<p>according to the KAPLAN scale</p>
<p>why not vertical distance, I always thought that the vertical components do not affect horizontal components… I mean I would think that air resistance could really affect an object with a wacky shape?</p>
<p>well kaplan scale I hear is lame and is sooooooo inaccurate!</p>
<p>well if you look at collegeboard scale in 22 reals and kaplan they are similar in the 800s right?</p>
<p>-For the one regarding electrons hitting tv screen, Im pretty sure they lose kinetic energy. Losing nuclear potential eneergy makes no sense, as electrons dont have a nucleus, and losing electrical potential energy doesnt make much sense to me either, considering there is no circuit involved. It seems that high speed particles are being slammed into a wall, and in that case, kinetic energy is lost.
-For the one with horizontal motion, I think the answer was variations in the earths gravitational field. Since the question stated the projectile was close to the earth’s surface , those variations are so freaking small that they are essentially non existant. Thus, variations in the gfield have the least effect on the horizontal distance covered. (Is this the same question you are referring to?)
- For the thin film intereference question, the answer was diffraction. Reflection, refraction, phase change, and intereference are all involnved, but diffraction is not.</p>
<p>oh yeah it was variations in gravation field (but I think this was a diferetn question)…and yes it was kinetic…thank you!</p>
<p>o crap…I think I put phase change for that film interference question didn’t think…but I still don’t get why its diffraction…like it kinda makes sense but I don’t know exactly why</p>
<p>"If the
electron and nucleus are dissociated AND have kinetic energy, then the total
energy of the system is the kinetic energy. "

<p>oh wait nvm…I just found this</p>
<p>the question was what was LOST
and
Electrical potential energy lost = kinetic energy gained

<p>Phase change is an integral part of thin film intereference… The colors only form because the phase of the wave changes going form one medium to another.</p>
<p>ITS phase change… Phase change pertains to changing from solid to liquid to gas. When I read the question, I was like…ok all these terms pertain to waves, but where did phase change come from the blue? You get what I am saying…you could have arrived by process of elimination as well.</p>
<p>I also agree its EPEnergy.</p>
<p>thats not why color forms. Color forms because of dispersion and reflection. When you shine white light through the prism, they disperse into various colors…not phase change. In addition, the reason why we see things in general like a blue baseball cap is because it absorbs all the colors except blue which is reflected into our eyes. I see diffraction working in the way that the waves bend to fit through the filament. Or at least I see it better working in this case as opposed to phase change.</p>
<p>wait, what was the answer to the fractals question? insect? lol, i had no idea what the heck that was. I almost got the Galileo’s question wrong but last minute i was like, wait, inertia, NEWTON!</p>
<p>HEY, also, did the SAT II trick us by using 2 grams on a question to calculate a simple PE instead of KG…?</p>
<p>damn yeah you are right…anyway</p>
<p>about that galileo problem</p>
<p>“Galileo is traditionally credited with being the first scientist to formalize this concept of inertia”"</p>
<p>The Early Discover…
Galileo 1564-1642; discovered Inertia. What is Inertia is your question?
Inertia is the finding of Galileo that states any outside influences tends to remain in motion if in motion and at rest if at rest.</p>
<p>wait, what was the “variations in the Earth’s gravitational field” question you mentioned adimeola14?</p>
<p>By phase change, I dont mean changing from one form of matter to another. I mean the phase of the actual waves change. This happens as a result the refraction that occurs when a wave goes from one medium (air) to another (glass). Also, I did not mean thats why colors form in the general sense, but as it pertains to this question. The band of colors that form (in this specific question) because of constructive intereference of waves that reflect from the initial barrier of air/glass, and the waves that reflect from the second barrier glass/air. </p>
<p>Diffraction, in a ageneral sense, is the ability of wave to bend around obstacles. I don’t see how this occurs with thin film interference.</p>
<p>For the variations in the gfield quesiton, I think it was one of the ones towards the end. IT was something like, which of the following factors least contribute to the horizontal distance traveled by a projectile.</p>
<p>shoot I am so worried, what do you think is a 750… I can already count that I have gotten about -13 for raw score from this thread alone.</p>
