Electrons photo-emitted from a material in a ups experiment can be viewed as free particles. a photon of wavelength 100 nm is absorbed by an electron that was in an orbital with an ionization energy ie of 8.41 ev. use the relationship between kinetic energy and momen tum (ke = p2/2m) and the quantum mechanical momentum operator ˆp to solve for the exact unnormalized wavefunction of the electron that is photo-emitted from the orbital.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
