nvm i figured it out. it was not in reference to n=4. equation used would be wavelength = 2L/n Homework Statement An electron is in an infinite potential well of width L. Which is not an allowed deBroglie wavelength for the electron to have when n=4? wavelength(k) = 3L, 2L, L/2, or L/3Homework...

if i can take out EMF and make R2 = 1 i come out with 4 as my answer. can anyone confirm?

totally forgot but here it is

Part A: For what ratio of R1 and R2 would power dissipated by the resistor of resistance R2 be the same for circuit A and circuit B? current for R2 of circuit A is (2EMF)/(2R1+R2) current for R2 of circuit B is (EMF)/[(R1^2/2R1) + R2) Part B: Under which of the following conditions would power...

i have a couple hours to submit. any more comments? thank you guys

sorry that's not supposed to be ^-6. its positive any input would be great. I only have one submission left so i have no room for error

thank you for the welcome! forgot to include units in question. nC charges and cm distances can someone check this? Potential at a point: V = kq/r. Relative to charge 1, the potentials are V1i = (9x10^9)(3.55)(10^-9)/(0.275) = 116 volts before, and V1f = (9x10^9)(3.55)(10^-9)/(0.10) =...

Homework Statement Two stationary positive point charges, charge 1 of magnitude 3.55 and charge 2 of magnitude 1.60 , are separated by a distance of 55.0cm. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges...
