Demonstrate that 1 pc equals 3.09 × 1013 km and that it also equals 3.26 light-years. show your calculations.

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

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?
