Newton’s 1st law of motion definition Newton’s first law of motion states that ” A body continues its state of rest or of uniform motion in a straight line provided no net force acts on it.” According to newton’s 1st law of motion ,a body at rest remains at rest provided no net force acts on it.This part of law ...

Chemical effects of current Voltmeter or coulomb meter: The vessel in which electrolytes is carried out.It is also called electrolytic cell. Electrolyte: An ionic compound in aquas solution or molten state is called an electrolyte. Electrolysis: On passing current through an electrolyte,chemical changes occur in electrolyte and substances are liberated at the electrodes.This process is called electrolysis. Faraday’s laws: First ...

converging and diverging lenses ray diagrams In mirrors images are formed through reflection but lenses form images through refraction.This is explained with the help of ray diagrams as follows: Image formation by convex lens ray diagrams Image formation in convex lens can be explained with the help of three principal rays shown in figure. The ray parallel to the principal ...

what is multivibrator? The name mutivibrator designates a group of the circuits widely applied for switching as shift registers or temporary memories and as square were timing oscillator or clocks. These circuits are basically closed loop feedback circuits operating with the feedback. Types of multivibrators There are three general types of multivibrators, which are: The astable or free running mutivibrator ...

Schrodinger time dependent wave equation What is schrodinger wave equation? In classical mechanics the motion of a body is given by Newton’s second law of motion.But elementary particles like electron,protons and photons possess wave properties as well,therefore another equation instead of Newton’s second law equation ( F=ma) is required for describing their motion.The new equation must take into account wave ...
