differences in meaning between the terms relation and relation schema

The principle of homogeneity of dimensional equation is used to derive a relation between various physical quantities. To derive a physical relation, the dependent factors of a given physical quantity is found. Assuming its dimensions in terms of these factors, the fin..

The relative tendency of acids to transfer a proton to a common base, generally water is expressed as the relative strength of bronsted acids. For example, HCl has a higher tendency to transfer a proton to H 2 O than CH 3 COOH. This means HCl is a stronger acid than a..

Basic Terms Connected to Waves - The four important terms used in the study of waves are Wavelength, Amplitude, Frequency and Wave velocity. Wavelength ' l ' is the distance between two consecutive points on the wave which are in the same phase. (same phase means same ..

>The homeostatic mechanisms work on a negative feedback. In order to ensure the continuation of species, all living organisms exhibit reproduction. The entire cellular information is stored in the DNA which undergoes replication to transfer the information to the successive generations. The surviva..

Derivatives are also used to trace the graphs of different functions. To optimise the value of a differentiable function of practical use, derivatives of the functions are applied. This chapter reveals with many more application of derivatives such as determining the relative e..

This quantum number denotes the sub-level or subshell in a given principal energy shell to which an electron belongs. This is also called secondary quantum number. It is denoted by l and corresponding to each value of n, there are n possible values of l ranging from zero to one less than n for that..

When two solid surfaces slide over each other, a frictional force acts between them that opposes the relative motion of the bodies. Similarly, when a layer of a liquid slips on another layer the two exert a tangential force on another. This opposes their motion. The property of a liquid ..

/content/math/number-theory/polynomials/polynomialsindex.php'>polynomials as the product of two or more polynomials is called factorisation. If A = B x C, B and C are called factors of A. Methods of Factorisation: (i) Common factors (ii) By expressing as difference of squares (iii) By gro..

Introduction - The term ecology is derived from two Greek words (oikos - means 'house' or place to live and logos means 'a discussion or study'). Literally, ecology is the study of organism 'at home' in their native environment. The term was first introduced ..

Limitations of Dimensional Analysis - Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors while deriving the relation conne..
