Awheel is rotating at a rate of 2.0 rev every 3.0s. through what angle, in radian , does the wheel rotate in 1.0s?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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 .

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
