A source of emf is connected across one pair of opposite junctions (A and C), and a galvanometer G across the other opposite pair (B and D). The key K 1 is closed first and then K 2 . The value of R is varied till the galvanometer shows no deflection, i.e., I g = 0. Then, the bridge is said to b..

Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric power consumed P..

Introduction - Newton's laws of motion help us to analyse many kinds of motion. But the analysis is complicated, requiring details about the motion that we simply do not kno..

Potential energy is the energy possessed by an object by virtue of its position or condition. Kinetic energy = 1/2 mv 2 Potential energy = mgh Law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another. Powerh..

If m and n are positive integers, and then (i) a m a n = a m + n [Product Law] (ii) [Quotient Law] (iii) (a m ) n = a m n [Power Law] (iv) (ab) m = a m . b m (v) (vi) a o = 1 (vii..

Introduction - Newton's laws of motion help us to analyse many kinds of motion. But the analysis is complicated, requiring details about the motion that we simply do not know. Long ago, people used to trade by only exchanging products when the concept of 'money' was yet to be introduced. ..

Introduction - If m is a positive integer, a x a x a . m times is written as a m . a is called the base and m is the power. We read it as "a raised to the power m". The power is also called "the index" or "the exponent..

Experimentally, it is found that the rate of a reaction is proportional to the concentrations of the reactants raised to some power, provided that other factors, which also affect the rate of the reaction are kept constan..

Let us see what is actually taking place in the following examples: Steam engine: The coal burns. Heat due to the combustion of coal converts water into steam. The expansive force exerted by the steam on the piston of the engine moves the locomotive. Chemical energy is converted to heat energy and ..
