A baseball is travelling towards a player's bat with a speed of 40.0 m/s. After being hit by the bat, the baseball is travelling wtih a speed of 45.0 m/s in the opposite direction of the initial velocity. Calculate the impulse imparted to the baseball.

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 .
