What can be expressed by the unit slug?
A. Weight
B. Mass
C. Length
D. Area

Hint: The slug can be considered to be the unit of mass in a weight-based system of measures. The most notable within the British system of imperial measurement and in the customary measures system of the United States. The systems of measure can be either explained as mass and derive a force unit, explaining a base force and finding out the unit of mass.

Complete step-by-step answer:
The slug can be considered to be the unit of mass in a weight-based system of measures. The most notable within the British system of imperial measurement and in the customary measures system of the United States. The systems of measure can be either explained as mass and derive a force unit, explaining a base force and finding out the unit of mass. A slug can be expressed as the mass that can be accelerated by one feet per Second Square if a force of one pound (lbf) is acting on it. One slug is defined as a mass equivalent to $32.1740lb$. That is in kilogram we can express it as $14.5939kg$. This has been done on the basis of the standard gravity and the international foot. At the surface of earth, a body is having a mass of one slug acting a force downward of nearly $143N$ or $32.2lbf$.

So, the correct answer is “Option B”.

Note: The slug will be a part of a subset of units that can be called as the system gravitational FPS, one of the many like the specialized systems of mechanical units created in the late nineteenth and the twentieth century. This has been mentioned as geepound, which is the name for this unit in early literature.
