In the diagram, q1 = +4.88*10^-8 C. What is the potential difference when
you go from point A to point B?
Include the correct sign, + or -.
B
0.538 m
91 + 1.36 m
(Hint: Does V go up or down when you go
from B to A?) (Unit = V)

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

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?

When a pair of 10-n forces act on a box of candy, the net force on the box is a 20 n. b about 14 n. c zero. d any of the above depending on the directions of forces.
