<p>I remember there was a question about temperature using q=mct but I don’t remember the numbers lol. ring any bells for anyone?
Also there were those problems where an charged rod was touched to that sphere with wires thing but I’m pretty sure I got the answers to those wrong</p>
<p>oh, and the Rutherford’s experiment problem- the results were that some particles were completely deflected by the foil</p>
<p>I’m not sure about the lenses question. Also, for the moon and earth, I thought it was at point D where the overall gravitational force is zero. I thought that was harder than the Barrons practice tests. -.-</p>
<p>I thought the charged rod one was that the angle would increase only. Anyone remember the one about the temperature & wall thickness question?</p>
<p>can anyone confirm D as the answer for earth and moon problem?</p>
<p>The diverging lens was virtual and upright…
The Rutherford was a few would experience large aberrations–I got that wrong…</p>
<p>I am interested in the charged rod/charged rod after being grounded. I think the grounded one was zero/zero?</p>
<p>Also, there was one about two sides of an object are attracted to the same end of a magnet, thus it’s ferromagnetic.</p>
<p>I recall there being a question with a square loop of wire and a magnetic field directed into the page. This wire was rotated various ways, and it asked for which ones induce a current? I put I and II only.</p>
<p>It is one and two only, the third one has no change in area, thus no flux.</p>
<p>What about the one with the tube and the water in it?</p>
<p>No, but the loop is moving in the magnetic field right? Rotation counts as some kind of movement, so there will be an induced current.
I put all three.</p>
<p>is ferromagnetic confirmed? isn’t it permanent south poles?</p>
<p>Ferromagnetic is right, because a magnet can NEVER have two south poles, only one N and one S.</p>
<p>What was the letter of the answer for that question (ferromagnetic)?</p>
<p>@kinetix64 - The tuning fork? I put 7 cm.</p>
<p>for the temperature and wall thickness problem- I put E [I think it was like 17 degrees and the thickest]</p>
<p>ok guys i have 55 questions out of 75 in the consolidated list we need the remaining 20…</p>
<p>does anyone have any idea what the curve could be like? because this was much, much harder than the tests in the PR book</p>
<p>something about the force a charge feels in between the plates of a capacitor.</p>
<p>Oh yeah, there was also one where a wave or something passed through two strings of different thicknesses, or something like that.</p>
<p>Timothycho - can you post ur full list? :)</p>
<p>A block on a wheel attached to a string attached to spring scale attached to fixed object >> measure the kinetic friction between the wheel and the block ?</p>
