A bronze statue of mass 200 kg is being completely submerged a water tank , held motionless by a cableabove the bottom of the tank . Find the tension in the cable . Use 8100 kg / (m ^ 3) and 1000 kg / (m ^ 3) for the densities of bronze and water , respectively . 2. A certain compact disk (CD ) can be treated as a solid disk with radius of 6 cm and mass 10 grams . Originally . the CD is freely spinning at an angular speed of 6 rad /s. A small piece of chewing gum of mass 5 grams dropped vertically down on the CD at a distance 6 the axis of revolution . Find the new angular speed in rad /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.
