Pressure decreases when _____a)Only the force is increased but not the...
Explanation:
Pressure is defined as force per unit area. Hence, pressure can be decreased by either decreasing the force or increasing the area. The correct option is (D) because it includes both options - decreasing the force and increasing the area.
- Decreasing the force: If the force acting on a surface decreases, then the pressure exerted by the surface will also decrease. This is because the force is directly proportional to the pressure (P = F/A). If the force decreases, then the pressure will also decrease.
- Increasing the area: If the area of the surface on which the force is acting is increased, then the pressure will also decrease. This is because the area is inversely proportional to pressure (P = F/A). If the area increases, then the pressure will decrease.
Therefore, either decreasing the force or increasing the area can cause a decrease in pressure. The correct option is (D), which includes both possibilities.

Pressure decreases when _____a)Only the force is increased but not the...
Pressure (P) = Force (F)/Area (A)
From the above equation, we can infer that the pressure is inversely proportional to the area and directly proportional to the applied force.
Hence, the pressure will decrease when force is decreased and/or area is increased.
