The Sankey diagram below shows the energy transfers in a computer Arrow A shows the useful energy outputs. This useful energy is carried away from the computer by sound and what else?

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
