Right. Sorry, I had a brain cramp. For part (C), does this look right? (10 T*m^2 - 0) / (0.2s) = 50 V

That's weird that the question is phrased like that. What is the difference between 0.1^2 m and 0.1 m^2? And how do I set up the equation in this case?

Right, but I don't know how to solve for velocity in this case so that KE formula isn't helping me much right now. Was I correct in that the total energy of the system is 3.375 J and I can subtract the PE at 10cm (1.5 J) from that to solve for the KE? This would give me a KE of 1.875 J. If I am...

Haha, I often don't trust myself and like to be sure I'm doing it right. I used the conservation of energy law. I'm still kind of confused which velocity formula to use in this case and how to solve that part of this question?

So for (b), it's just (100)(0.1^2)(1). That gives a magnetic flux of 1. Does it look like I did that right?

Homework Statement A coil of wire with 100 turns and a cross-sectional area of 0.1 m2 lies with its plane perpendicular to a magnetic field of magnitude 1 T . (a) Describe in your own words the meaning of magnetic flux (b) calculate the total magnetic flux passing through the coil. (c) If the...

Oh wow, good catch. I would have messed that up. So now the PE equation becomes U = 1/2(300)(.10)^2 which equals 1.5 J. Then for the KE would I subtract the total energy of 3.375 - 1.5 to get 1.875 for my KE?

OK, I think I fixed it and got 3.375 J. So the KE would be zero because the spring hasn't moved yet? Making the total energy of the system the 3.375 J? I think the original question wants the PE and KE while its stretched at its original distance of 15 cm prior to release and then the...

Thank you. So is the correct formula for PE in this case, U = 1/2 kx ^2? If that is correct, I set up the equation as U = 1/2(300)(.15)^2 and get 506.25 as my answer. Did I do that correctly?

Homework Statement Suppose that a 200g mass is oscillating at the end of a spring upon a horizontal surface that is frictionless. The spring can be compressed and stretched, and has a spring constant of 300 N/m. It was originally stretched a distance of 15 cm from its equilibrium...
