For the circuit shown in the figure (Figure 1) a 20.0 Ω resistor is embedded in a large block of ice at 0.00∘C, and the battery has negligible internal resistance.

At what rate (in g/s) is this circuit melting the ice? (The latent heat of fusion for ice is 3.34×105J/kg.)

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

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?
