An incompressible box is completely submerged in water at a depth of 60m. The volume of the box is 8L and it has a mass of 30 kg. The buoyant force on the box is 70N.. If the box is brought to a depth of 90m, stae what the mass of the box ,volume of the box and buoyant force on the box will be? Choose one correct answer with the correct units of measure. A. Mass = 70kg Volume = 8L Buoyant force = 30N B. Mass = 30kg Volume = 8 m3 Bouyant force = 70 pound C. Mass = 30kg volume = 8L Buoyant force =70N D. Mass = 8 kg Volume = 30L Buoyant force = 70N
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.

A. Mass = 70kg
Volume = 8L
Buoyant force = 30N
B. Mass = 30kg
Volume = 8 m3
Bouyant force = 70 pound
C. Mass = 30kg
volume = 8L
Buoyant force =70N
D. Mass = 8 kg
Volume = 30L
Buoyant force = 70N
