Magnetism and Matter Peter is doing some experiment on a bar magnet. He heated the bar magnet to 1000 degree centigrade and then cooled in a magnetic field-free space. He is surprised to see the behavior of bar magnet. Can You guess?
In 1887, Hertz conducted an experiment. It was showing that when a light beam falls on a metal surface, there was some kind of electrical reaction. But he did not attempt to explain it. Can you guess, the cause behind this effect? Particle in a Box
Particle in a Box We are going to discuss a single particle in a box classical as well as quantum. Classically: Particle confined in a box and walls of the box are completely rigid. So it can not penetrate the walls of the box. Particle have momenta p so it has kinetic energy E and it …
Integration Formulas In mathematics, science, and engineering an integral is a useful tool that can describe displacement, area, volume, and other properties that arise by combining infinitesimal data. Integration is the 2nd most important operation in calculus, with its inverse, differentiation, being the first. Differentiation Formulas

The derivative of a real-valued function measures the rate of change of a quantity (dependent variable) with respect to change in another quantity (the independent variable). Derivatives are a fundamental tool of calculus. Integration Formulas

When two charged conductors of the same size and same material carrying charges are brought in contact and separated, the charges on each of the conductors will be. Differentiation Formulas Integration Formulas Electronics short questions Physics 11 Practice Test Wireless Electricity (Tesla Coil)
In physics, there is a need to formulate the basic laws in the so-called invariant form that is one that doesn’t depend on the chosen coordinate system. And here comes the Tensors very handy to handle such conditions. by: James Moriarty
