```										Mass can be defined as quantity of matter contained in the body.But then what is this "quantity of matter" anyway?!!!
So in the sense of classical physics mass is simply the measure of inertia which resist change in its state of rest or having uniform velocity upon applying force.
Special theory of relativity incorporates mass-energy as being one entity & rest mass term is used for the (classical sense) mass.

the moment of inertia of a solid flywheel of radius 0.1m about its axis is 0.1kgm2. a tangential force of 2 kg wt is applied through the circumference of flywheel with the help of string and...

ANS: 2m/s 2 equate the torque I alpha = force * r (r = radius of wheel) 0.1*a/r = 2*10* r ( a = accelaration) therefore a=2m/s 2 ( r = 0.1m)

In H.C.Verma physics-1 book they mentioned that “resultant force perpendicular to the velocity has no effect on speed , hence kinetic energy is not changed” , how ?

Yes, beacuse when resultant force is perpendicular to the velocity then, the Power that is: dot product of force and velocity would be zero. as the angle is 90 degree. Hence with zero Power ...

tell me why Magnetic lines form continuous closed loops

Magnetic monopoles do not exist in nature. Hence the fields lines always begin from one end (pole) have to end at the other (pole).
