<p>“did any one get gravitational potentional as an answer to the question that asked what did not follow the relationship?”</p>
<p>“i put the one that had x ~ 1/r i think it was electrical potential one. all the others (Fg, Fb, light and sound intensity) had x ~ 1/r^2 relationship.”</p>
<p>anyone remember this question? I put the above answer too. :electrical potential doesn’t follow…</p>
<p>Also did u guys get “fundamentals of pitch?” for any of the answers?</p>
<p>and do you remember when u tie the knob of a guitar, what stays the same? or was it what changes?</p>
<p>for the guitar knob questions, the choices were
<p>@howon: that’s a hard question…I have no idea…</p>
<p>BTW…there’s a question…</p>
<p>Which particle has the smallest mass?</p>
<p>It’s quark or electron?</p>
<p>electron.
the second answer was quark</p>
<p>really…when I searched the Internet, it’s said that electron has the smaller mass…</p>
<p>i think it was a change in frequency and tension. As you turn the knob, the frequency increases and therefore the tension does also…anyone agree?</p>
<p>It was a change in frequency and tension.</p>
<p>The tension changes because the string gets tighter.</p>
<p>The frequency changes because when you tune a guitar, pitch changes, and pitch = frequency.</p>
<p>@basketball1 : yup…I have the same idea…</p>
<p>The answer to the particle with least rest mass was photon it has a rest mass of zero.</p>
<p>@wheels25, the question was asking for a substance with the least mass among the non-zero-mass particles.</p>
<p>ya i chose electron, not photon…</p>
<p>does anyone remember
“the fundamentals of pitches” as one of the answers?</p>
<ol>
<li>something that had 3kg, 2kg on a same rope ->did u guys also choose 1ma?</li>
<li>remember the questions in part A? there was a table about numbers and the following three questions were 1) constant acceleration? 2) falling to the ground 3) i dont remember the other. (They were #3-#5)</li>
<li>something that had 1.5 and 1.33 was it about focal points?</li>
<li>8m/s^2, 3kg, 12N thingy… what did u choose?</li>
<li>time relativity… somebody in the spaceship and somebody on earth. I chose answer c. I’m not sure though.</li>
<li>elctric field
ㅡㅡㅡㅡㅡㅡ +
ㅡㅡㅡㅡㅡㅡ -
which one gets the most force? I chose the one closest to (+) am I right?</li>
<li>there was a mirror reflecting lights betwen air and water. which one does not show the correct reflection? I chose (E).</li>
</ol>
<p>does anyone remember the answer to the question about a speaker being spoilt??..was it resonance?..or beats??</p>
<p>at hellosat. i choose 2ma, as the mass conected to that string was 2 (the tension in the other string would have been 5ma). </p>
<p>For the questions in part A. I got all 3’s for one. THe one that was going up 1,2,3. and the one that started high and ended at 0.</p>
<p>Don’t remember the focal point one. </p>
<p>Can you explain number 4 more?</p>
<p>The time relativity was the man on earth sees everything for more time, more time passes by for the man on earth. (If that sort of was an answer, forgot the exact wording).</p>
<p>I choose the one closest to the (-), but i remember being very unsure about that answer can you explain your reasoning</p>
<p>And yeah the incorrect ray was E.</p>
<p>also i know i’ve asked like 10 times, but was the wavelength that was not possible that one that had a right side up bump and then an upside down bump? (the one with one full wavelength)</p>
<p>****, I omitted 14 on this test. I only did 3 practice tests so my time management wasn’t very good and I couldn’t really go back to the ones I left. Hopefully of the ones I did 50+ are correct so I can score a 720+. I’ll be happy if I get that since I didn’t know a word of Physics until a couple of months ago.</p>
<p>do you guys think -25 on raw score can still get me 700?</p>
