A student made a hypothesis that a wooden block
with different friction matences on the
base warud need different weights to
make it move across a table. The friction
matencus are sandpaper, cardboard glass,
acumivicum and wood. Plán an investigation
to rest the students hypothesis.

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?
