  IT is a salware that works as an interface between a user and the computer hardware. The primary objective of an operating systernis to make computer system convenient to use and lo ulilize computer hardware in an cicient manner. The operating system performs the basic tasks such as rebot Notes pdf ing input from the keyboard, processing instructions and sending output to the screen We'll be covering the following topics in this tutorial: 🔴What is Operating System 🔴Functions of operating system 🔴 Different type of operating system 🔴How Operating System Work 🔴Characteristics of Operating System What is Operating System The Sottware is the Non-Touchable Parts of the Computer and Softwares are those which are used for Performing an Operation so That Software are just used for Making an Application but hardware's are those which are used for performing an Operation Note copy pdf https://photos.app.goo.gl/ZeiTKJMwFMY9UvYw6 Computer note pdf nerating system software that is re...

  Elasticity Marcas certain mass and occupies some space. A matter can exist in three state solid, liquid Waste properties and liquid state of matter accounts for surface tension and viscosity while the ange. Each state of matter has some distinct properties. For example, the solid state of matter has keudes. These atoms and molecules hold each other with a force. The force which is responsible to dus state of mutter accounts for pressure, diffusion etc. A matter is made up of atoms and bell the acamus together is called interakonic force and the force responsible to bind the molecules of matter is called intermolecular force. A expression for energy stored in a stretched wire is derived. Finally, related problems both students will get knowledge about young modulus, bulk modulus, shear modulus and Poisson's ratio. Numerical and conceptual are solved in the text as examples and for practice, they are given in the as which enable the students to solve the problems related to this ch...

Scroll down for pdf of thermodynamics  Thermodynamics THERMAL EXPANSION • The increase in shape and size of a material on heating is known as thermal expansion • As the temperature of a material increases, molecules occupy greater space and hence their intermolecular space increases and so, the body gets expanded. . As the temperature of a material decreases, molecules come closer and hence their intermolecular space decreases and so, the body gets contracted. • Thermal expansion is minimum in solids,more in liquids and maximum in gases because intermolecular forces. • Solid _______ > length, area and volume Liquid and gas___________> volume                 Solid expansion The increase in shape and size of a solid on heating is known as solid expansion. Solids have all three kinds of thermal expansions. - Linear expansion - Superficial expansion - Cubical expansion Linear Expansion • The increase in length of solid on heating is known a...

  Rutherford Atomic Model This model was put forward by emest Rutherford in 1911 with help og du particle scatering experiment: Io this experiment, bombarded thin sheet of gold foil (0.0004 cm thickness) with (alpha particle ) positive particles equivalent to helium ion , He²+ which were obtained from a radioactive substance. The scattered alpha particles were observed on the surface of a circular zinc sulphide screen as they produce tiny flashes with a help of movable microscope as follows: a) Most of the a-particles passed etreoight through the gold joll undeglected. b) Some of the a- particles deflected through small angles. c) Few of the in particles were reflected or returned back (about lin 20,000).    🔴On the basis of above observation, it can concluded that a) since most of the Alpha particles of passed straight through the gold foil undeflected, it indicates the most of space inside the atom is empty. B. The cause of deflection of Alpha particles through small a...
