<p>Yup, it’s B</p>
<p>Could anybody comment to see if my explanation for the FRQ is correct?</p>
<p>Badly, badly need 2009 MC answers. Please PM me if you can help !</p>
<p>^ Here is the answer key

<p>^^, I thought your answer seemed legit, I tried something else and realized that I was finding something different from what they wanted. But your answer seems right.</p>
<p>I thought CB charged for released exams…</p>
<p>Yes, but these are just the answers, they put those up for free.</p>
<p>Would they ask us on the multiple choice a question like which of the following is equivalent to 1 F.
Then they put like C^2 * s^2/ kg *m^2, etc.</p>
<p>Oh dear god, I’m gonna fail.
Trying to study everything would be a waste, since like no colleges accept credits for this >:O</p>
<p>^^ I’ve never seen a question like that, and I hope not but isn’t it like 1 C/V</p>
<p>^ Yeah that could work too, except it wasn’t an answer choice. The one that I put up is the answer.</p>
<p>Can we try to get a list of the units most commonly used for physics b. I will start off:
v (velocity) = m/s
a (acceleration) = m/s^2
Force = Newtons
Capacitance = Farad
p (momentum) = kg *m/s
energy = joules
work = joules
electric charge = Coulomb
electric potential = Volts
Current = Amps
Pressure = Pa
Resistance = Ohm
Magnetic Field = Tesla
Temperature (Thermodynamics) = Kelvin
Power = watt</p>
<p>I have the test in like 6 hours because I’m International…Hopefully the Form B will be easy lol</p>
<p>Is the answer A?</p>
<p>^ Based on the free response from previous years, it seems that the international version is much harder. Maybe the multiple choice will be easier for you though.</p>
<p>Thank you !!!</p>
<p>More random review! Don’t confuse your electric laws.</p>
<p>F = kq1q2/r^2
U = kq1q2/r
V = kq/r</p>
<p>This is from a previous post. What is U?</p>
<p>Question 48 from the 1998 exam:</p>
<p>A single circular loop of wire in the plane of the page is perpendicular to a uniform magnetic field B directed out of the page. If the magnitude of the magnetic field is decreasing, then the induced current in the wire is:</p>
<p>The correct answer is that the current is moving counterclockwise around the loop. How do we know that the direction is counterclockwise? I know that the induced field is also coming out of the page, but I would think that would make a clockwise current.</p>
<p>^ Your thumg points in the direction of the magnetic field which is up, therefore, your fingers curl in the direction of the current which would make it counterclockwise</p>
<p>We were discussing this in the AIM review chatroom but we were having some trouble with it.</p>
<p>A tuning fork is used to create standing waves
in a tube open at the top and partially filled with
water. A resonance is heard when the water level
is at a certain height. The next resonance is heard
when the water level has been lowered by 0.5 m.
If the speed of sound is equal to 340 m/s, the
frequency of the tuning fork is?</p>
<p>miami - I was under the impression that the thumb was current / velocity for the right hand rule and that the fingers were field.</p>
