given a rectangular box of mass 100kg, length 125cm and width 0.25m is placed on a surface as shown below. calculate the pressure exerted by this box on the surface

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 .
