Which best explains why replicating an experiment should be done by someone other than the person who originally did the experiment? a It shows that the results are the same using different methods.
b It shows that the experiment is easy to do.
c It shows that the results are as expected.
d It shows that the experiment is designed properly.

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?
