ISOLATED SYSTEM:
"When a number of bodies are like that they can exert force upon one another and no external agency exerts a force on them, they are said to form an isolated system".
EXAMPLES:
The molecules of a gas enclosed in a vessel at constant temperature form an isolated system of interacting bodies. The enclosed molecules collide with one another because of their random motion but no external force acts on them.
in some case we take y=-g but in some case we take y=g... why???
in hydraulic jacks,a car is placed at one end and force is applied on the other piston to lift it . if the areas of the pistons are A1 and A2 such that A2>A1,in which end should t
It is a highly doped p-n junction which is not smashed by high reverse current. The breakdown voltage is made very sharp. In the forward bias, the zener diode do as ordinary diode.
