Ok guys, I’ve got a few multiple choice questions I need help with. Here they are, and thank you in advance! All I know for this one is……Ql/Qh = Tl / Th Leaning towards B. 1. In a Carnot cycle A. Qh > Ql * Th/Tl B. Qh = Ql * Th/Tl C. Qh < Ql * Tl/Th D. Qh = Ql * Tl/Th We are able...

Hi, I just wanted to know if anyone knows any good online resources that deals with the conceptual side of electricity and magnitism. I find that on tests, I do very well on the numeric problems, but when it comes time to the conceptual MC questions, I do poorly. I found one site...

hey, I'm currently in grade 12, and so far we just started a review over the conservation laws unit, which includes (energy related theorm, work, power, momentum, collisions, mechanical energy ect.) Anyways I can't seem to figure out these two multiple choice theory questions, was hoping...

Can anybody help me on this question, I'm stuck. I have a picture attached for clarification. Consider two concentric spherical conducting shells. O is at the center of the shells. THe inner shell has radius a and charge q1 on it, while the outer shell has radius b=3a and charge q2 on it...

Hi guys, I need help with the following problem I couldn't figure out: 1) A block of mass 2 kg slides along a horizontal tabletop. A horizontal applied force of 12 N and a vertical applied force of 15 N act on the block. If the coefficient of kinetic friction between the block and the table...

Two balls of masses m1 and m2 are moving along x-axis w/ velocities, v1>v2>0. After transforming from the lab frame to the center-of-mass frame, what are the velocities of m1, v1com, and mass m2, v2com? Vcom is the center of mass velocity for the system of both balls. The choices are...

Hey everyone... since the AP Physics C Exam is coming up next monday I was looking for old exams online (multiple choice exams) to study from. I've been searching for days and haven't come up with anything. Does anyone know where I can find old multiple choice sections of the AP Physics C Exam.

Heres an AP multiple choice problem that's giving me some trouble: If \frac{\,dy}{\,dt} = ky and k is a nonzero constant, then y could be a) 2e^{kty} b) 2e^{kt} c) e^{kt} +3 d) kty + 5 e) \frac{1}{2}ky^2 + \frac{1}{2} Dont quite know where to begin?
