Question

how can we decrease pressure?
decrease force
decrease area
increase speed

Explanation:

Step1: Recall pressure formula

Pressure is defined as $P = \frac{F}{A}$, where $F$ is force and $A$ is area.

Step2: Analyze each option

• Decrease force: Since $P \propto F$, decreasing $F$ reduces $P$.
• Decrease area: $P \propto \frac{1}{A}$, so decreasing $A$ increases $P$.
• Increase speed: Not related to the basic pressure formula here.

Answer:

decrease force
