Answer:
Appropriate MKS or SI units for angular momentum are kilogram metres squared per second (kg-m2/sec). For a given object or system isolated from external forces, the total angular momentum is a constant, a fact that is known as the law of conservation of angular momentum.

Answer:
(a) J sec
Explanation:
The joule-second is a unit of action or of angular momentum. The joule-second also appears in quantum mechanics within the definition of Planck's constant. Angular momentum is the product of an object's moment of inertia, in units of kg⋅m2 and its angular velocity in units of rad⋅s−1.
