Final answer:
The physical quantity represented by the formula f/a (force/area) is pressure.
Step-by-step explanation:
The physical quantity represented by the formula f/a (force/area) is pressure.
Pressure is defined as the force applied per unit area. It is a measure of the force exerted on a surface.
For example, when you press down on a table with your hand, the force you apply is spread out over the area of contact, resulting in pressure. Pressure is commonly measured in units such as pascals (Pa) or pounds per square inch (psi).
