You must get beat up a lot, huh? Or at least made fun of. Thus your only way of feeling "big" is trying to talk big and condescending to people who need homework help. I actually found the answer from a classmate. You're a loser, dude.

I did that for half an hour before posting this thread. I also explained my attempt at a solution in my original post. Like I said in my OP, I don't expect anyone to just give me the answer (I'm above a 3.5 gpa and don't do the cramster thing like most people do... they just screw themselves...

Come on guys. 73 views and not one reply?

Homework Statement Compute the magnitude and location of the resultant of the parabolic loading shown in the figure below. The slope of the parabola is zero at the origin. See figure: http://imageshack.us/photo/my-images/819/prob6.jpg/ Homework Equations The Attempt at a...

Can someone help, please? I don't expect anyone to just solve the problem and give me the answer like they do on cramster, but statements like the two above (with all due respect) don't really help me one single iota. No, I'm not sure if that equation works 100% of the time (obviously, it...

Homework Statement Two waves of the same frequency have amplitudes 1.02 and 2.27. They interfere at a point where their phase difference is 59.5°. What is the resultant amplitude? Homework Equations Resultant Amp = (Amp1 + Amp2)cos(theta/2) The Attempt at a Solution Okay this...

That was the right answer, but could you please explain the reasoning again? Is it that magnetic flux has to be increasing/decreasing to create an EMF, and if the flux is constant then EMF is zero? Because I had another homework problem which I already solved that said, "An electric generator...

Anyone have any ideas?

I'm confused. Are you saying the EMF is zero? I only have one guess left before the problem is marked wrong.

Homework Statement In the figure below, a circular loop of wire 12 cm in diameter (seen edge on) is placed with its normal at an angle θ = 30° with the direction of a uniform magnetic field B of magnitude 0.60 T. The loop is then rotated so that N rotates in a cone about the field direction...

That did it! Thanks.

Homework Statement In the figure below, an electron moves at speed v = 93 m/s along an x-axis through uniform electric and magnetic fields. The magnetic field B is directed into the page and has magnitude 4.00 T. In unit vector notation, what is the electric field? Figure...

Well I finally figured it out! You just ignore cos(theta) so it becomes i=t/(NAB). Thanks for pointing me in the right direction.

Ok, I just did a quick test and found that a perfect square gives the max area. But still, I'm not sure what to do with cos(theta).

It tells me that the length of the length of the wire (or, loop perimeter) is 6.8cm. I'm sure I could use that as a circumference to find the radius if it were a perfect circle (and hence, the area), but how do I know which shape to use? "Max value of torque" tells me that (if I'm supposed to...
