QUESTION 3 A submarine is sinking but then adjusts its ballast tanks so that the buoyant force of the sub is the same as the weight of the boat. Which of the 3 scenarios will occur? Orise Obsink O remain at depth QUESTION 4 A person is submerged slightly in the water and they stretch out their body and spread their arms and legs. displacing a lot of water, so that their buoyancy is greater than their weight. What will occur. O remain at depth. Obrise eventually floating on the surface. Sink to the bottom
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.
