<p>also, for the electric force where the charges are doubles, masses are doubled, distance is doubled, the force stays the same i believe</p>
<p>For fractal pattern I put insect. Honestly, when I saw that question I was like Whatthe****? I have never heard of what a fractal pattern is, and I didn’t know it had anything to do with physics…</p>
<p>Yeah, ****tt stays the same…</p>
<p>i put insect too, but apparently some insects show fractal patterns</p>
<p>bwt what did you guys get for the photoelectric effect one? (when photon hits, there was a graph)? at frequency 5, 0 eV energy electron is released, righT?</p>
<p>Yeah thats what I got…any other questions you remember?</p>
<p>There was an electric field line one; some momentum ones, a heat one with two boxes, couple of displacement vs velocity graph ones, and the other ones I remember are all somewhere in this thread.</p>
<p>if the electric field line one is the one with one positive and one negative, the field lines go towards the negative, the heat one where there were 3 scenarios, the only valid one was the one in the middle, in which the 15C box heat was flowing into the 10C box. </p>
<p>for the P vs. V graph, more work is done by the path with greater area under it, im not sure if it was path x or path y, but it was the one that was two straight lines</p>
<p>I think the PV question asked about change in internal energy, which would be equal for both…then the next question about adiabatic expansion was work done BY the gas and pressure decrease</p>
<p>hey for the one where the charges double and the masses double, did the question also say that the distance between the charges doubles as well?</p>
<p>Yes it did</p>
<p>One of them asked for during an interval, which had the greatest instaneous speed between t=0 and t=2. I picked the one that looked like a big hump.</p>
<p>thats correct, the one with the big hump also had the lowest average velocity</p>
<p>Fundamental frequency is pitch. When a string vibrates, lots of waves of various frequencies pass through the string. The fundamental frequency is the frequency that is the “strongest,” or the frequency that we hear when we hear the string vibrate. Aka the pitch.</p>
<p>Good point… any counterarguments?</p>
<p>what was the question again?</p>
<p>it’s because the fundamental frequency determines resonance? objects vibrate at multiples of the fundamental frequency, producing resonaance i guess</p>
<p>pitch vs. resonance…what does fundamental frequency depend on?</p>
<p>@swagmaster420x i’m pretty sure resonance applies only when the frequency of the outside force and the fundamental frequency are aligned, otherwise resonance wouldn’t be produced. and because the frequencies other than the fundamental frequency don’t align with the fundamental frequency, resonance isn’t produced.</p>
<p>hmm yea it might be pitch idk</p>
