A thin spherical shell with a mass of 3.80 kg and a diameter of 0.200 m is filled with helium (density = 0.179 kg/m). It is then released from rest on the bottom of a pool of water that is 4.25 m deep. (a) Neglecting frictional effects, determine the value of the acceleration of the shell. (Enter the magnitude in m/s.) Enter a number. differs from the correct answer by more than 10%. Double check your calculations. m/s (b) How long does it take for the top of the shell to reach the water's surface (in s)?
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.
