Find angle between two vectors

The angle between two vectors is referred as a single point, known as the shortest angle by which we have to move around one of the two given vectors towards the position of co directional with another vector.It is found by using the definition of the dot product of two vectors. How to find Angle b/w two vectors? We can find ...

examples of entropy in everyday life

Entropy measures how much thermal energy or heat per temperature.Campfire,Ice melting, salt or sugar dissolving,  popcorn making and boiling water are some entropy examples in your kitchen. The concept of entropy was introduced into the study of thermodynamics by Rudolph Clausius in 1856 to give a quantitative basis for the second law. It provides another variable to describe the state of ...

Newton’s law of universal gravitation formula

Newton’s law of gravitation can be stated as:”Everybody in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.” Newton went a step further in his analysis of gravity. In his examination of the orbits of the planets, he ...

types of electromagnetic radiation in order of increasing wavelength

There are 7 types of electromagnetic radiation which are given in the  list below: Light Infrared radiation Microwaves radiations X-rays Ultraviolet radiations Radiowaves Gamma rays What is Electromagnetic Spectrum? The word spectrum comes from a Latin word meaning “form” or “appearance”. Other familiar words from the same root include “spectacle” and “species.” Newton introduced word to describe the rainbow-like image ...

State faraday’s law of electromagnetic induction

Faraday’s law of induction was discovered through experiments carried out by Micheal Faraday in England In 1831 and by Joseph Henry in the United States at about the same time. *Even through Faraday published his results first, which gives him priority of discovery, the SI unit of inductance is called the henry (abbreviation H). On the other hand, the SI ...
