Final answer:
Angular momentum is determined by the product of an object's mass, its angular velocity, and the distribution of its mass, also known as the moment of inertia.
Step-by-step explanation:
Understanding Angular Momentum
Angular momentum is determined by the product of an object's mass, angular velocity, and the distribution of its mass around its axis of rotation. It is an important concept for analyzing the motion of astronomical objects, such as planets in orbit. The distribution of mass is sometimes referred to as the object's moment of inertia, and angular velocity is the rate at which the object rotates.
Thus, the most accurate answer to 'Angular momentum is determined by what?' is d. Product of its mass, angular velocity, and distribution of its mass.
