A first-order differential equation is said to be linear if, in it, the unknown function y and its derivative y' appear with non-negative integral index not greater than one and not as product yy' either. Hence, a first-order linear differential equation is of the form: where p and q are given r..

. Thus, state of the system may be defined as its conditions of existence of the system when its macroscopic properties have definite values. When the state of a system changes its macroscopic properties also change and acquire new definite values. The macroscopic properties are properties which ar..

The disadvantages associate with digital communication systems include (i) Increased transmission (ii) Increased system complexity Although digital communication is becoming increasingly attractive for practical use, it is a fact that analog communication systems are still in existence. Most of th..

. Depending upon the number of valence electrons, the elements of the p-block exhibit variable oxidation states. The general electronic configuration of these elements is ns 2 np 1 - 6..

Valency is the combining capacity of an atom. It is equal to the number of electrons the atom loses, or gains or shares when it combines with one or more atoms. Depending on whether the atom loses, gains or shares electrons, the valency may be positive or negative or neutral respectively...

fig 2.34 - Metal deficiency defect due to missing of a cation of lower valency and presence of a cation of higher valency Occurs when metals show variable valency. Example: Transition elements It occurs due to the missing of a cation from its lattice site and presence of the cation w..

It is the modern theory on organic evolution. It is a synthesis of the ideas from the theory of natural selection and the mutation theory. The theory is the outcome of the thinking of recent biologists such as Huxley, Haldane and Dobzhansky. Neo-darwinism is based on three principles namely; genot..

Nucleus - Nucleus is the most conspicuous and the largest organelle in the cell. Most cells have a single nucleus and hence they are described as uninucleate. Some cells have two nuclei (binucleate) while a few may be even multinucleate. A nucleus generally occurs in all eukaryotic cells. However, ..

Zeolites - Shape-Selective Catalysis by Zeolites - Shape-selective catalysis are those reactions that depend on the pore structure of the catalyst and the size of the reactant and product molecules. In such reactions, zeolites are used as catalysts. Zeolites are microporous aluminosilicat..

or or Now, if V 1 is the volume of a gas at temperature T 1 and pressure P 1 . V 2 is the volume of same amount of gas at temperature T 2 and pressure P 2 , th..
