Oh gee i need ! use the diagram below to answer this question. as the ball moves from point a to c what is happening to the energy? explain the potential energy and the kinetic energy values at point a as compared to c (use complete sentences to answer the question).

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
