Calculate the frequency of an electron traveling at 1.85 X 10^7 m/s. Since the velocity and mass of the electron are known, I tried to use the De Broglie wavelength formula: let L = lambda, h = plancks constant L = h/mv and I got 3.94*10^-11 for the wavel...

Oscilloscopes have parallel metal plates inside them to deflect the electron beam. These plates are called the deflecting plates. Typically, they are squares 3.0 cm on a side and separated by 5.0 mm, with very thin air in between. What is the capacitance...

A Tevatron can accelerate particles to energies in the TeV range (1.00 tera −eV = 1.00×10^12 eV ). Its circumference is 6.40 km, and in a certain medical experiment protons will be accelerated to energies of 1.25 MeV and aimed at a tumor to destroy its ce...

A circuit has R = 16.6 Ω and the battery emf is 6.50 V . With switch S2 open, switch S1 is closed. After several minutes, S1 is opened and S2 is closed. 1) At 2.14 ms after S1 is opened, the current has decayed to 0.235 A . Calculate the inductance of the...

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wavelength of 515 nm ? The index of refraction of the film is 1.32, and there is air on both sides of the film. -------------- I kn...

For the latter method, I understand the concept of path independence and computing work using the two points, such that (U = potential energy) W = Uf - Ui And I understand that V (electric potential) is V = U/q0 such that U = Vq And that V is also equal t...

current*, not charge I'm not sure I can concert the voltages into amps without knowing power
