The set shown below is a function. {(ball, circle), (kite, diamond), (stop sign, octagon)} create an additional ordered pair that would make the relation no longer a function. in complete sentences, explain why the additional ordered pair affects the relation's ability to be a function. complete your work in the space provided or upload a file that can display math symbols if your work requires it.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

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?
