You need to design an industrial turntable that is 56.0 cm in diameter and has a kinetic energy of 0.260 J when turning at 37.0 rpm (rev/min). Required:
a. What must be the moment of inertia of the turntable about the rotation axis?
b. If your workshop makes this turntable in the shape of a uniform solid disk, what must be its mass?

Which of the following are properties of mechanical waves? check all that apply ⭕️ particles of the medium move back and fourth, but do not move with the wave. ⭕️ the particles of the medium always move parallel to the wave motion. ⭕️ wave motion begins with a disturbance in the medium. ⭕️ waves transport energy from a source outward, away from the source.
