Consider an object being immersed through a height h in a fluid. The pressure at the surface is smaller than the pressure at the bottom of the object. This difference in pressure, Dp, is given by:
Dp = hdg
where d is the density of the fluid
and g is the acceleration of free- fall
Now, Dp can be expanded as the ratio of force to area. So:
F/A = hdg
where F is the force exerted on the body
and A is the bottom area of the object
=> F = Ahdg
=> F = Vdg
since Ah = volume V
=> F = mfg
where mf is the mass of fluid in the volume V ( mf = dV from the definition of density)
=> F = Weight of fluid displaced (shown)
The force F is the upthurst on the body.
No, American law is only based on some concepts of Roman law. American law is more closely and largely based on English law. Remember our Founding Father were all Englishmen, so they would naturally incorporate the English concepts into ours.
Symbols of chemical elements are derived from the chemical name.
The term 'broad' originated in the 16th century Middle English language, derived from the Old English word 'brad'. In the 16th century, it was used as an adjective to describe something that was wide or large in size, scope, or extent. The term has since taken on more meanings, and it is now commonly used with a variety of other words to refer to a range of things from physical attributes to abstract concepts. Wide or large in size, scope, or extent Physical attributes Abstract concepts

Basic principles are ideologies that guide a school of thought or for that matter an entire institution.These are laid down by thinkers or the heads of an institution.It can be called a charter that helps anything to work with the help of the bylaws that are set.
There are many ways in which the principles of teaching can be derived. One way in which a principle is derived is the need for change or efficiency.
There is nothing democratic about the Judeo-Christian tradition. The political tradition derived from Judeo-Christianity is tyrrany and authoritarianism. Democratic concepts were derived from Hume, Locke and Hobbes.
The principle that all species were derived from common ancestors is known as Common descent.
Pressure = force / area.
Pressure is defined as the amount of force applied to a given amount of area. Therefore pressure is derived from force and distance. Force itself is derived from time, distance, and mass and area is derived from distance.
An easy way to do that is to weigh the object. In principle, the mass can be derived from the weight.
True
False.
Judicial principles were derived from ancient law codes and common law.
Yes, it is the derived unit for pressure.

"Buoyancy" is the term derived from the word "buoy," which means "float." Buoyancy is the tendency of a body to float or to rise when submerged in a fluid (partially above the surface or completely submerged beneath the surface). It is also the power of a fluid to exert an upward force on a body placed in it. According to Archimedes' Principle: An object in fluid is buoyed up by a force equal to the weight of the fluid which the object displaces. Buoyancy arises from the fact that fluid pressure increases with depth and from the fact that the increased pressure is exerted in all directions (Pascal's Principle) so that there is an unbalanced upward force on the bottom of a submerged object.
