In the HBr molecule, the mass of the bromine nucleus is 80 times that of the hydrogen
Question:
In the HBr molecule, the mass of the bromine nucleus is 80 times that of the hydrogen nucleus (a single proton); consequently, in calculating the rotational motion of the molecule, one may, to a good approximation, assume that the Br nucleus remains stationary as the H atom (mass 1.67 x 10-27 kg) revolves around it. The separation between the H atom and bromine nucleus is 0.144 nm. Calculate
(a) The moment of inertia of the HBr molecule about the bromine nucleus, and
(b) The rotational energies for ℓ = 1, ℓ = 2, and ℓ = 3.

In this experiment, we will discuss Newton\'s second law of motion. In this experiment, we use a bucket that is filled with water and attach it to a rope that passes from the pulley. A person is pulling the rope down to lift the bucket filled with water. The question is how much time does a bucket take to fall on the ground when we leave the rope? A 2.0 kg bucket is attached to a massless string that is wrapped around a 1.0 kg, 4.0 cm diameter cylinder. The cylinder rotates on an axle through the center. The bucket is released from rest 1.0 m above the floor. How long does it take to reach the floor?
