EXPLANATION
Question: What are the dimensions of angular momentum?
- a) ML²T⁻¹
- b) ML²T
- c) M²L²T⁻¹
- d) M²L²T⁻²
ANSWER: a) ML²T⁻¹
EXPLANATION:
The dimensions of angular momentum are a) ML²T⁻¹. Angular momentum is a rotational analog of linear momentum and is defined as the product of the moment of inertia and angular velocity. The moment of inertia has dimensions of mass times length squared (ML²), and angular velocity has dimensions of radians per time (T⁻¹). Multiplying these dimensions together gives us ML²T⁻¹, which represents the dimensions of angular momentum.
