Homework Statement A rectangular 20 turn loop that is 12 by 5 cm carries a current of 0.10A. It's hinged at one of the longer 12cm sides. It's mounted with its plane at an angle of 33 degrees to the direction of a magnetic field of 0.50T. What's the torque about the hinge line? Homework...

How about thinking about it this way? The plates and magnetic field are parallel to each other as the question says, and the velocity vector is in the same plane as the magnetic field. So they interact on say, the xy plane, and the electric field from the plates is always in the z...

Ah, I see. That was my main hangup. I considered if it was a trick question, but the way it's worded seems to just take it as a fact. Thanks for the help.

Yes, but what about the minimum delta V part? If the V which it is accelerated through were to increase and q remains the same, doesn't that mean the resultant velocity would be greater? And if the velocity is greater, doesn't that mean the magnetic force would be greater? That's what i don't...

You can find it on #5 http://www.hep.yorku.ca/menary/courses/phys2020/2009/p5.pdf" , if that helps. I think that I copied it exactly. No diagram is given.

Homework Statement An electron initially at rest is accelerated through a potential difference of
V and directed into a region with 1) two parallel plates separated by 20 mm with a potential difference of 20 V between them and 2) a uniform 0.5 T magnetic field which is parallel to the...

Under the Gauss' law section of the book. Homework Statement As you penetrate a uniform sphere of charge, E should decrease as less charge is inside the sphere, while E should increase because you are closer to the center of this charge. Which effect dominates? Homework Equations εΦ...

Yes, somehow I can grasp what an x y plane is, but what I meant was for clarification was what it was the y coordinate of. Is it saying the field is different at different y coordinates. And the only definition of flux we have been given to use is area cross magnetic field.

Okay but what variable is it? And why does calculating the flux involve doing an integral?

Homework Statement A 20.0 cm by 20.0 cm square loop of wire lies in the xy-plane with its bottom edge on the x-axis. The resistance of the loop is 0.520 {\Omega}. A magnetic field parallel to the z-axis is given by B = 0.790 * y^2 * t, where B is in tesla, y in meters, and t in seconds...

I'm sorry, I do not understand the initial question's wording about "bound state energy". I have never learned such a thing and I don't quite understand the question...I know how to plug things into formulas, I was hoping for a conceptual explanation of what this question describes...but you...

How do you know it is inelastic from the question? What is "bound state energy"? And how is that used to get the answer that the software gives me?

Homework Statement An atom of mass M is initially at rest, in its ground state. A moving (nonrelativistic) electron of mass m_e collides with the atom. The atom+electron system can exist in an excited state in which the electron is absorbed into the atom. The excited state has an extra...

Homework Statement A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x-axis be parallel to the ground and the positive y-axis point upward. In the time interval from t=0 to t=4 s, the trajectory of the car along a certain section of the...
