A car travels 300 km N in 6 hours. What is the average velocity of the car ( in km/hr)?

What is the most useful equation for electric power?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

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?
