The temperature of an object can change as a result of . A. heat remaining inside the object B. heat flowing into or out of the object C. the presence of air around the object D. the continued vibration of particles in the object

What are two different ways you could find the value of a? explain these methods.

The discovery of the electron as a subatomic particle was a result of

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?
