ML-1T-1 are the dimension of
Correct answer: D. viscosity
- A. angular momentum
- B. power
- C. impulse
- D. viscosity
Explanation
The dimensions ML-1T-1 indeed correspond to viscosity. The correct explanation for option D is as follows:Viscosity is a property of fluids that measures their resistance to flow. It determines how easily a fluid can be deformed under the influence of shear stress. The dimensions ML-1T-1 represent viscosity, where:M represents massL represents lengthT represents time In the context of the dimensions ML-1T-1, viscosity is proportional to mass divided by the product of length and time. This indicates that viscosity involves the interactions between mass, length, and time in the context of fluid flow.

About Dimensional Analysis
Dimensional analysis expresses physical quantities through fundamental dimensions such as mass, length and time. It checks dimensional consistency, helps derive relations and converts between unit systems, but cannot determine numerical constants or distinguish quantities with identical dimensions. Dimensional formulae must not be confused with complete physical units.
