Object A and object B are floating in space. Object A is twice the mass of object B. They are gravitationally attracted to eachother. Which object will accelerate towards the other more? a
They will accelerate towards each other at an equal rate.
b
Object B
c
Object A
d
They will not accelerate at all.

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?
