Answer:
The magnitude of the force exerted on the piston by the gas is 135 N
Step-by-step explanation:
The pressure of the gas, P = 450 Pa
The area of the piston, A = 0.3 m²
The force exerted on the piston by the gas is given as:
F = PA
F = 450 x 0.3
F = 135 N
The magnitude of the force exerted on the piston by the gas is 135 N
