Consider an electron moving in a constant homogeneous magnetic field b b there are no other potentials present a) write down the hamiltonian (hint: canonical momentums a, where a is the vector potential b) show that if one chooses the vector potential that only has y-component, the general solution of the wave function has plane-wave form in two of the three directions. c) find the allowed energy levels

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
