<p>@ems4106, I think I put that, too… but do you remember any of the other choices? :</p>
<p>i think Milikan’s experiment may have been one but i dont remember well</p>
<p>I am sure the answer was that some were partially deflected. Not completely deflected back.</p>
<p>i dnt know…velocity in the thick string is less but why the frequency the same?mass per unit length is greater than that of thin…so shouldn’t be the frequency less?what strategy u followed?</p>
<p>Was ferromagnetic one of the answer choices? I said that the magnet could be magnetized, which was choice D, I think.</p>

“To Rutherford’s surprise, most of the alpha particles were hardly deflected at all: they passed through the gold foil as if it were just empty space. Even more surprising was that a small number of the alpha particles were deflected at 180º, right back in the direction they came from.”</p>
<p>Neytiri…grvitational force strongst at point A…zero…i cant remembr the point but it was 1 unit left from moon</p>
<p>guys i’m 100% sure that for the one asking about which one exhibits wave properties, it is the double slit experiment. just google it. </p>
<p>and for the one with a capacitor, i think it’s asking for the force. if i remember correctly, i used these equations. electric pe = qv epe also = work = force X displacement, so force = qv/d. you can easily plug in q and v. but for d, it’s in between so it’s half the given distance. </p>
<p>by the way, can someone please confirm the picture with 3 loops. i know it’s 1 and 2 for sure, but can someone explain 3 (rotating around the axis)</p>
<p>I got 66 out of 75 for consolidated list now…9 more to track down</p>
<p>Thanks Charrizard.</p>
<p>Envymealways, did you get 4.5 * 10^something???
I think it was D?</p>
<p>@envymealways, in order to induce a current, the area of the wire has to change (flux = B x A) so if it’s rotating around an axis that’s in the same direction as the magnetic field, the area won’t change… or at least I hope this is right haha :)</p>
<p>in the 3rd one the loop does not cut the magnetic lines of force. this means that no flux change occurs. no flux change means no induced e.m.f… flux change only occurs when the current moves perpendicular to the magnetic field(flux cut) AND the wires(loop) move so that it also runs parallel to the field(no flux cut).</p>
<p>Consolidated List (65/75)
Force is NOT zero with a nonzero acceleration
Kinetic energy is not a vector
Two carts elastically collide, second one is 6 m/s
Inelastically collide and stick together for 1.5 m/s
Half life is 1 hr 20 min
A is proportional to b^2, straight line when it’s a vs b^2.
Constant acceleration graph is straight, velocity is parabola, displacement is upside down parabola.
Stars: quasar
Resistors: 12 and 4 in parallel, 3 ohms in series.
Kinetic energy for half the speed was 9J.
Capacitator: nonlinear, negative decay (doesn’t reach zero, but gets close).
Pulley tension 2W
Photoelectric: I and II - energy increases in electrons and photons, but work function unchanged.
amplitude and tension T1 = T2
Net force moon and earth –> D
Greatest magnitude moon and earth –> A
velocity less and frequency same for thick wire
light and 6 screens no light ?
light and 6 screens white color ?
3 second for ball to drop
refraction B reflection E
temperature goes to 20 celcius
1 m way up for the rider question
rutherford experiment some deflected
tuning fork 7 cm
same sign for two charges
current opposite magnetic field left
charges have same sign
PE of spring for the graph question (shaded area)
to the left centripetal force if you cut string
satellite orbiting earth question
2 charges point west answer is the point equidistant from the two charges
diverging lens either A or B the one that is upright i think
F=MA if you times F by 6 and m by 3 then it is 2a
bulb question is always on
Q charge grounded state zero zero
Q charge Q charge have the same charge
first four questions that were relatively easy matching the units
voltmeter and ammeter what is the correct electric circuit
special relativity question ?
Q = mcdelta T question ?
increasing angle when rod is brought close to the thing
finding electric force using F=eQ
one that I omitted by cant remember
sum of kinetic energy of two carts is 45 J
apparatus for circling thing is kinetic friction
I and II are correct for inducing current and III is not
magnetic force perpendicular which is for the two currents in opposite direction
two sides of an object attracted to N of magnet –> ferromagnetic
which one is higher for blue light –> frequency
bell question with the rider –> 250 N
impulse indicates change in momentum
last question which i dont remember
what can you determine in a period question
velocity = 60 angle = 37 degrees time =3 sec
sqr 2v question which i omitted
wave property of electron –> double slit experiment
change in in kinetic energy = 0
increase in velocity when the ball is placed higher</p>
<p>PLEASE write if there are unsure questions or answers…</p>
<p>just remembered, there was a question about a person hitting a weight up 5m to hit a bell and something about where would the weight have the greatest velocity…? answer choices were something like 1m on the way up/on the way down, 3m on the way up/on the way down…</p>
<p>Answer is 1 meter on way up.</p>
<p>If there is constant acceleration and the graph is a horizontal straight line, shouldn’t the velocity graph be a straight line with a constant slope instead of a parabola?</p>
<p>For the question about the inelastic collision between two cars:
if both masses were 2, and one was moving at 3 and the other at -6, the first one bounces back at -6 and the other one bounces back at 3 right? just want to make sure</p>
<p>how about the e=mc^2 equation</p>
<p>-did you mention this question - W=9 R=4 I=?,ANSWER IS 3/2-by saying bulb question?otherwise what is the bulb question.</p>
<p>-and what is the question which is Q=mct</p>
<p>-and also what was the question about F=e.q?</p>
<p>-is ferromagnetic answer different from the D one which is about magnetized stuff?</p>
<p>I don’t remember last question %percent but it was like elevator was going down with a=2 and its mass was 1.000 kg.so question was what was the tension,and basically it was mg-ma(1000.10-2.1000)=8000 N</p>
<p>and please can anyone elaborate on PE of shaded area question?</p>
<p>-ems4106,yep question was like that and answers was respectively 3,1.5 and 45 j for that question.</p>
