Homework Statement (a) The negative half-cycles of a sinusoidal waveform E(t) = E0*cos(omega*t) are removed by a half- wave rectifier. Find the Fourier series representing the resulting wave in the output. (b) Find the output produced by a full-wave rectifier, which inverts...

Homework Statement At what temperature T does the specific heat of the free electrons become larger than the specific heat of the lattice? Express T in terms of the Debye temperature and the electron concentration. Calculate T for copper (Debye = 343 K). Homework Equations...

ok, so I should use the g-factor for a proton that you gave. And I should use e = 1.6*10^-19, and I should use m = 9.11 X 10^-31 kg? Using that the magnetic field is equal to the frequency divided by ge/2m, I should be able to solve for the field that would produce nuclear magnetic resonance...

Homework Statement Nuclear magnetic resonance in water is due to the protons of hydrogen. Find the field necessary to produce NMR (nuclear magnetic resonance) at 60 MHz. Homework Equations These are the equations I think I'm supposed to use: omega (subscript zero) = gamma * B...

This is part of a longer problem, and probably obvious, but if I calculate this wrong, the rest of the calculations will be wrong too!... Question: Given the mass density, molar mass, and electrical resistivity of a substance at room temperature, how do you calculate the concentration of the...
