In algebra we come across certain products very frequently. For e.g., (a + b) 2 , (a + b) 3 (a + b + c) 2 etc. These are nothing but products of binomials or trinomials. We derive the formulae for these products and apply them whenever necessary. These expansions help us to avoid elab..

Calculation of Cell Potential
In an electrochemical cell, electrons flow from negative electrode to the positive electrode. This shows that there is a potential difference between the two electrodes. The minimum potential which causes the flow of the electrons from the negative electrode to the positive electrode is called em..
Field Due to an Infinitely Long Straight Charged Wire
Consider a thin long charged wire. Let the charge per unit length of the wire be l . To calculate the field at P we consider a Gaussian surface with wire as axis, radius r and length l as shown in the figure. This Gaussian surface that is, the cylinder is closed at each end by p..

The graphs of the given pair of functions intersect. Calculate their points of intersection algebraically. y = x 2 y = (- 1 7 ) x 2 + ( 8 7 ) x + 48 => (7, 49) and (- 6, - 36) or (7, 49) and (- 6, 36) or (7, - 49) and (- 6, 36) or (7, - 49) and (6, - 36)..
Derived Units
Derived Units - The units of all physical quantities can be derived from the seven basic units. These units are called derived units because they can be derived from the basic units algebraically by multiplication and division. It is frequently necessary to convert one set of un..
