Beyond due to the chaotic nature of the atmosphere, computer prog forecast accuracy falls off rapidly.

Which is the correct symbol for an isotope of iodine with 53 protons and 78 neutrons?

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 you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
