The Pendulum
The pendulum is a story about the everyday life of an ordinary couple caught in the chores of mundane city life. John Perkins and his wife Katy live in Frogmore flats. Caught in the inevitable routine of breakfast - office - supper - bed, they have a predictable existence everyday. The first few p..
Iso-electric Point
It is defined as the point at which a molecule exists as zwitter ion with no net charge. Thus, at this point the molecule is electrically neutral. The molecules have minimum solubility, maximum precipitability and least buffer capacity. The acidic amino acids and basic amino acids s..
Stefan-Boltzmann Law
The energy of thermal radiation emitted per unit time by a black body of surface A, is given by u = s AT 2 -----(1) where s is a universal constant known as Stefan-Boltzmann constant and T is its temperature on absolute scale. The measured value of s is 5.67 x 10 - 8 W/m 2 - K 4 . Equatio..

. The baffle will be effective at any frequency for which the distance from the front of the cone, around the edge of the baffle, to the rear edge of the cone, is greater than a half wavelength of the sound. For example, at 100 cycle the wavelength is l = 1,100/100 ft = 11 ft and the distance from ..
Origin of Resistivity
Origin of Resistivity - In electrostatic situations, the electric field is zero everywhere within the conductor, and there is no current. This does not mean that all charges within the conductor are at rest. In metals such as copper or aluminium, some of the electrons are free to move within the co..

Ionization is the property of isolated atoms in the gaseous state. Oxidation potential is the property when the metal goes into the solution as M + ( a q ) ions: The process of oxidation potential could proceed as: The overall tendency for the change depends upon the net..

Surface tension is also related to the intermolecular forces in the liquid. The molecules in liquids are held closely and hence attract each other. A molecule in the bulk of the liquid is attracted equally on all sides so that the net attractive pull on the molecule is zero. However, a m..
The Superposition Principle
The principle states that when a number of charges are interacting , the resultant force on a particular charge is given by the vector sum of the forces produced by the individual charges. If several point charges q 1 , q 2 , q 3 .............. q n simultaneously exert electric force on the c..

Half Life of a Reaction - Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction is given as In general, for a reaction of ord..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
The tutors are amazing. They are very committed in helping students solve the questions and explains all the steps beautifully. So 5 stars for Tutor Vista.
