Hello. I am studying for my final and I can't remember how to find the induced magnetic field. I need it because, in my right hand rules handout that i must know, it says put your thumb in the direction of the induced magnetic field and you will curl your fingers into the direction of the...

A resonant circuit in a radio receiver is tuned to a certian station when the inductor has a value of 0.151mH and the capacitor has a value of 21.2pF. Calculate the frequency of the radio station. Frequency is 2.81 MHz ( I got this one right) B) what is the wavelength of the radiowaves...

In a certain RLC circuit, the rms current is 6.72A, the rms voltage is 230V, and the current leads the voltage by 55.9 Degrees. a)what is the resistance of the circuit? b)calculate the total XL-Xc c)Calc. the average power dissipated in the circuit. a) 1.92E1 Ohms b)? c)8.665E2 J I...

That doesn't seem to be working, anymore ideas? Am i even going about this problem the right way?

A 14.2m long steel beam is accidentally dropped by a construction crane from a height of 9.53m. The horizontal component of the EArth's magnetic field over the region is 16.4 uT. What is the induced Emf in the beam just before impact with the earth, assuming its long dimension remains in a...

Ok, I have been working on this problem for about 2 hours now, and I still can't get the right answer..could someome help me? two wires carry currents of I=5.12A in opposite directions and are separated by a distance of d0=9.33cm. (the wire on the left has I going up and the one on the right...

do you mean: Ex=(kq/r^2)cos and Ey=-(kq/r^2)sin...if so I don't know how to get the radius without the length of the string.

I still can't figure it out..I have q=(mgtan)/ E What I can't figure out is E. I know how to work the problem in reverse, when Given E and having to find Fx and Fy. Then finding the Magnitude (E= sqrt(fx^2+Fy^2)).

I have been working on this problem all night. I am not looking for a numberical answer, just help with the equations. A charged cork ball of mass 1.15 g is suspended on a light string in the presence of a uniform electric field. When the electric field has an x component of 3.05E+5 N/C, and...
