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.
Demerits of Vacuum Diode over Semiconductor Diode (i) Bigger in size (ii) Less efficiency (iii) Expensive

A 985-kg car travelling south at 29.0 m/s hits a truck travelling 18.0 m/s west, as shown in the figure below. After the collision, the vehicles stick together and travel with
A high-performance dragster with a mass of m = 1333 kg can accelerate at a rate of a = 23.5 m/s2. Write an expression for the magnitude of the net force, FNET, that propels the dr
It describes the temperature above which the material loses its spontaneous polarization and piezoelectric characteristics.
(1) These rays transmitted in the forward direction of medium with a finite speed. (2) Energy and momentum are transmitted in the direction of propagation of waves without real
Presumptuous that it is understood that the object is in front of the mirror and anything on the other side of the mirror is behind the mirror is the following statement sufficient
explain quantization of charge
Ans) In the first one..... F=ma...the only force which acts is F...which causes an acc. of ''a'' to the body of mass m... and as the force=>F=ma but on the second... let .
INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
