What is the angular momentum of the disk about the axle?

L =  0.5*M*R^2 * w

Explanation:

Solution:-

- The angular Momentum (L) of a rigid body about any axis is given by the following relationship:

                                     L = I*w

Where,

             I : Moment of inertia of the rigid body

             w: The angular speed of the rigid body.

- The moment of inertia (I) for a disc is given by:

                                    I = I_disc

                                    I = 0.5*M*R^2

Where,

            M : Mass of the disc

            R : The radius of the disc.

- Hence, the Angular momentum (L) of the disc rotating about an axle is:

                                  L =  0.5*M*R^2 * w

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
