A wheel 1.5m in diameter with an angular acceleration of 2rad/s^2. If the wheels initial angular velocity is 0.45 rad/s, what’s the angular velocity after 5 s? What’s the angle if it rotates in 5 seconds?

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 .
