ML-1T-1 are the dimension of
- A
angular momentum
- B
power
- C
impulse
- D
viscosity
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 mass
L represents length
T 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.
The dimensions of angular momentum are ML2T-1, where M represents mass, L represents length, and T represents time. Angular momentum is associated with rotational motion.
The dimensions of power are ML2T-3, where M represents mass, L represents length, and T represents time. Power is the rate at which work is done or energy is transferred.
The dimensions of impulse are MLT-1, where M represents mass, L represents length, and T represents time. Impulse is the change in momentum of an object.
