) John and Jane step onto the dance floor about 2.0 m apart at the Junior Prom and they feel an attraction to each other. If John's mass is 90.0 kg and Jane's mass is 15.0 kg, assume the attraction is gravity and calculate its magnitude.

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 .
