basic division definitions

Basic Proportionality Theorem (B.P.T.) will be more useful in the topic 'SIMILARITY'. Division of a line segment into equal parts. Divide a line segment of length 8.4 cm into 5 equal parts. AB = 8.4 cm 1. Draw AB = 8.4 cm and through A draw another line AX at an acute angle to A..

Notation: Usually a polynomial is denoted by P(x) and if k is any number then P(k) denotes the value of P(x) at x=k. The degree of a polynomial: If a o ? 0, then the polynomial P(x) or f(x) is of degree 'n' i.e., it is the highest power of the variable x in the rational and integ..

Polynomials - An expression of the form in which a i are numbers belonging to some number system and 'n' is a non-negative integer, is called a polynomial. a i are called the coefficients of if a o 0, the polynomial is said to be of degree ..

Meiosis-I (Prophase I, Metaphase I, Anaphase I and Telophase I) Chromosome number is halved (n). Two daughter cells are formed. Meiosis-II (Basically a mitotic division resulting in the formation of four daughter cells with (n) chromosome..

Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO 2 ...

A basic salt is formed when there is a higher proportion of the base in the reaction between an acid with a base, than is necessary for the formation of a normal salt. Example: Basic copper carbonate CuCO 3 .Cu(OH) 2 Basic lead carbonate (white lead) PbCO 3 .Pb(OH)..

All these hydrides have one lone pair of electrons on their central atom. Therefore, they act as Lewis bases. They can donate an electron pair to electron deficient species (Lewis acids). Down the group, the basic character of the hydrides decreases. For e.g., NH 3 is distinctly ba..

Absolutely dry ammonia or pure liquefied ammonia is neutral. In the presence of water however, it forms ammonium hydroxide, which yields hydroxyl ions. As a result of this reaction, it exhibits basic nature. It is a weak base and is perhaps the only gas that is alkaline in nature. ..

Ohm's law The potential difference across the conductor is directly proportional to the current flowing through it. Solutions obey Ohm's law like metallic conductor..
