On the set of positive integers Z + , the relation a divides b is reflexive not symmetric transitive On the set of positive integers Z + , the relation "a not reflexive not symmetric transitive On the set of triangles, the relation similar to ..

From the above observation, we find (i) sin A = cos B where A + B = 90 o \ Sine of an angle = Cosine of its complement sin A = cos (90 - A) o sin 40 o = cos (90 - 40) o = cos 50 o (ii) = tan A (iii) By Pythagoras theorem a 2 + b 2 = c 2 \ sin 2 A + cos 2 A = 1 These..

Conductors - All metals possess a large number of free electrons. Under ordinary conditions, these electrons move randomly in such a way that the net flow of charge across any section of the metal conductor is zero. Thus a conductor is void of any charge as such. But when the free electrons are mad..

The dimensional formula of a physical quantity can be obtained by defining its relation with other physical quantities and then expressing these quantities in terms of mass [M], length [L] and time [..

. I mean, what does he gain by watching Cartoon Network?" Nothing, say teachers, educationists and parents in unison. And so, TV is outlawed (Tom Cruise allows his children nothing more than 45 minutes of television a week) and the PC a totem. Though it occupies pride of place at both home and scho..

The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atom..
