Number is one the the basic concepts of mathematics. It is probably the very first idea we learn as a child. Here I want to present various numbers in use. Real Number system The set of all rational and irrational numbers taken together form a new system of numbers known as real number system. One [ ] The post Number System first appeared on Physics and Universe .
LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. LaTeX is available as free software. Latex has been widely used in the field of physics and mathematics where writing equations is a [ ] The post Writing equations with…

Production: X-ray is produced under the action of incident electron that excites an electron in inner orbit if target atom. How is is different for light? Both are electromagnetic wave but X-ray has short wavelengths ranging from 0.001 Angstrom to 100 Angstrom. X rays are also more energetic than visible light and can penetrate through [ ] The post X-Ray first appeared on Physics and Universe .
3I Atlas just flew pas out sun and has revealed new details about its nature and makeup. In any comet’s life the most exciting time is when its approaches the sun and is at its shortest distance from Sun. We call this phase Perihelion. During this time comet gets to face full force of the [ ] The post 3I Atlas – what’s going on? first appeared on Physics and Universe .
Oscillator is an electronic circuit that produces a repetitive electronic signal (sine wave or square wave). Some examples of signal generated by oscillators includes signal broadcast by radio and TV transmissions, clock signals and sound produced by electronic beeper and video games. Phase shift oscillator An oscillator circuit which uses RC network as a combination [ ] The post Oscillator first…
General Conference on Weights and Measures in 1971 adopted seven quantities as fundamental base quantities. These seven base quantities are known as International System of units or SI in brief. There quantities listed below are seven fundamental quantities Quantity SI Unit Symbol Length meter m Mass kilogram kg Time second s Electric current ampere A [ ] The post SI Units first appeared on…
The mass of a planet can be determined by observing the time period of its satellite. Let M be the mass of the planet and m be the mass of its satellite. For the satellite to be in the circular orbit, gravitational force is equal to centripetal force. If r be the radius of the [ ] The post Calculating mass of planet first appeared on Physics and Universe .
Solar constant is the amount of energy received from the sun per second per unit area by a perfect black body on the earth, the area being placed normal to the direction of radiation. Let S be the solar constant r be the distance of the earth from the sun and R be the radius [ ] The post Solar constant and temperature of the Sun first appeared on Physics and Universe .
The magnitude of star is the measure of its brightness. When measured from the earth, two stars that differ by one magnitude have a brightness ratio of 2.512 If two stars of magnitude and possess brightness and respectively, then The post Magnitude of star [Formula] first appeared on Physics and Universe .
Let P be a particle on a smooth plane inclined at an angle alpha to the horizon. If ABC represent a vertical section of the inclined plane through P, AB is the line of greatest slope and the angle ABC is alpha. The acceleration of P due to gravity is g and it is vertically [ ] The post Motion down an inclined plane first appeared on Physics and Universe .
