Paring the Forces Compare the magnitude of the electromagnetic and gravitational force between two electrons separated by a
distance of 2.00 m. Assume the electrons have a mass of 9.11 x 10-31 kg and a charge of 1.61 10-19 C. Round to
two decimal places.

What are the north and south poles of a solenoid change with?

Select all the correct answers. which three statements about electromagnetic radiation are true?

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?
