The maximum kinetic energy of the photoelectrons emitted by a metal exposed to light of a given wavelength happens to be equal to the work function of the metal. How does the energy of the incoming photons compare to the maximum kinetic energy of the emitted photoelectrons

Let v1, v2, w be three linearly independent vectors in r 3 . that is, they do not all lie on the same plane. for each of the following (infinite) set of vectors, carefully sketch it in r 3 , and determine whether or not it is a vector space (i.e., a subspace of r 3 ). explain your reasoning
