In the Archimedes' Principle lab a cylindrical hanging mass was fully submerged into a beaker of water. How did this change the forces on the beaker/water system? O The mass pushed down on the beaker/water with a new force and the normal force increased to compensate. O The tension in the string acted on the beaker/water system after the mass is submerged. O An upward force acted on the water due to the mass and the normal force decreased to compensate. No changes occurred. The forces on the beaker/water system were still just the normal force and the weight.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
