7.Consider a block of wood that floats with 60% of its volume above water along a portion of creek at Brookside, Baguio City. (The volume of the block is 0.5 m3) Suppose this block of wood is placed in a liquid of density 500 kg/m3. What will happen to the block of wood? O A. All of these are possible B. It will sink. O C. It will float with no part of it above the surface of liquid. D. It will be partially submerged.
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.
