Answer:
Force=30N
Area=120cm²
=120/10000 m²
=12/1000m²
Pressure=force/area
=30/12/1000 or 30/0.012
=2500 N/m²
=2.5x10³ n/m³

Answer:
The pressure experienced by the surface is 2500 Pa.
Explanation:
The applied force, F = 30 N
The area on which the force is applied, A = 120 cm² = 0.012 m²
The pressure experienced can be found using the following equation,
P = F / A
∴ Pressure, P = 30 / 0.012
= 2500 N/m²
Pascal is also a unit of Pressure. It is denoted as Pa.
∴ The pressure experienced by the surface is 2500 Pa.
