principles of classification

Biogas is produced as a result of anaerobic fermentation of biomass in the presence of wate..

Archimedes' studied the upthrust acting on a body, when it is partially or completely immersed in a fluid by performing several experiments and then stated the following principle known as the Archimedes' Principle..

All moving objects in our daily life have well defined paths or trajectories. The path or trajectory of an object can be determined by knowing its position and velocity at various intervals of time. However, Werner Heisenberg, in 1927, pointed out that we can never measure accurately both the..

The same principle can be generalized to three or more events occurring in succession as follows: If n operations can be performed in m 1 ,m 2 ,m 3 ,...m n ways respectively, then all n operations in succession can be performed exactly in m 1 ,m 2 ,m 3 ,...m n ways. The above prin..

The principle states that when a number of charges are interacting , the resultant force on a particular charge is given by the vector sum of the forces produced by the individual charges. If several point charges q 1 , q 2 , q 3 .............. q n simultaneously exert electric forc..

The underlying fact on which the principle is based was discovered by Archimedes in about 300 B.C. The story goes that the King of Sicily suspected that the goldsmith has mixed some silver in his crown and cheated him. Without destroying the crown he wanted to know the truth. Archimedes ..

Let y = f (x). The derivative of f at x is denoted by f '(x). Finding the derivative of a function using the above definition is called differentiation from first principles..

Archimedes' Principle - An iron needle sinks in water but a huge ship floats on the surface of water. All objects whether inside the liquid (or fluid) or partially inside, appear to be lighter than in air. This is because liquids (or fluids) exert upward force on the immersed object. This..

Principle of Moments - If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equ..
