What factors affect the gauge pressure within a fluid?

a. fluid density, depth, free-fall acceleration
b. fluid volume, depth, free-fall acceleration
c. fluid weight, depth, free-fall acceleration
d. fluid mass, depth, free-fall acceleration

The factors that affect the gauge pressure within a fluid are:

a. Fluid density: The density of the fluid plays a role in determining the gauge pressure. The higher the density, the greater the gauge pressure.

b. Depth: The depth of the fluid also affects the gauge pressure. The greater the depth, the higher the gauge pressure.

c. Free-fall acceleration: The free-fall acceleration, typically denoted as 'g,' is the acceleration due to gravity. It affects the gauge pressure, with a higher acceleration leading to a higher gauge pressure.

Therefore, the correct answer is a. fluid density, depth, free-fall acceleration.

The factors that affect the gauge pressure within a fluid are:

a. Fluid density: The density of the fluid affects the pressure exerted by the fluid. A denser fluid will exert a higher pressure.

b. Depth: The pressure within a fluid increases with depth. This is due to the weight of the fluid above exerting a force on the underlying fluid.

c. Free-fall acceleration: The acceleration due to gravity affects the pressure within a fluid. As the acceleration due to gravity changes, it affects the weight and thus the pressure exerted by the fluid.

Therefore, the correct answer is option a. fluid density, depth, free-fall acceleration.
