Final answer:
The force exerted by the gas on the piston can be calculated using the formula Force = Pressure x Area. If the piston is moved to a different height, the force exerted by the gas will change.
Step-by-step explanation:
The force exerted by the gas on the piston is calculated using the formula:
Force = Pressure x Area
Given that the pressure of the gas is 150 Pa and the height of the piston is 0.02 m, we can calculate the force using the equation:
Force = 150 Pa x 0.40 m² = 60 N
If the piston is moved to a height of 0.03 m, the force exerted by the gas can be calculated using the same equation:
Force = 150 Pa x 0.40 m² = 90 N
Therefore, the force exerted by the gas on the piston increases from 60 N to 90 N when the piston is moved to a height of 0.03 m.
