A 20-ton truck collides with a 1500-lb car and causes a lot of damage to the car. During the collision:

A. the force on the truck due to the collision is slightly greater than the force on the car.

B. the force of on the truck due to the collision is exactly equal to the force on the car.

C. the car and the truck have the same magnitude acceleration.

D. the force on the car due to the collision is much greater than the force on the truck.

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?
