Answer 1

• Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

Answer 2

Answer:

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P).
