Marissa designs a robot that goes on a mission to mars. the acceleration of gravity on mars is 3.7 m/s^2. the robot has a mass of 18 kg.

a. how does the mass of the robot change once it gets to mars? explain

b. how does the weight of the robot change once it gets to mars? explain

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?
