FRQ #3
a) I left out resistor 2. So the differential equation should have a 2R in front of dQ/dt instead of just R.

Mr. Tsao, for question 2a) When the bar is moving to the right with the magnetic flux changing by the magnetic field pointing out of the plane increasing. Wouldn’t the induced magnetic field be into the plane increasing? Leading to a net force to the right instead of to the left? This would also lead to a change in your response in the graph that follows after 2 questions.

Hey Allen for question number one for the free body diagram. Shouldn’t Fsp = Fc + mg, so why are the relative arrows not reflecting that the forces are balanced.

Was there another form? I had totally different questions

BTW, I have a question. I know that the frqs are released by collegeboard, but what about the weights of different parts of each frq? Like, some parts of an FRQ may have more weight (more points) than other parts. Are the weights of each part of each frq released yet?

Hey Allen Tsao, for the question 1, for cii, I also got a calculated value that is drastically different than the real value, are you sure that's normal and that I'd receive full credit for that?

For 3)a, we have 2 resistors, so shouldn't the loop equation contain a 2R?

[baeasy]

Amazing explanation.
When will they release the Ap Physics 1 FRQs? And will there be a review for it?

[emilyli]

Mr. Tsao I was wondering if college board had released the paper for physics 1 this year and I was wondering will you be doing it also

Is there a way to see the multiple choice
