Under the action of constant force, a 2kg block moves such that its position x as a function of time is given by X=t^3/3 ,where x in meters and t in sec , the workdone by force in first 2 seconds isA 26.6 jB 3.3 jC 16 jD 32 jSolution) v=dx/dt=t^2,a=dv/dt=2t,f(t)=ma(t),w=∫f(t)*v(t) dt (from x=0 to x=2 sec)
Transformation Hardening The main features of the laser as a heat source for transformation hardening are: (A) Clean energy source. (B) Energy is localised: no heat spillage.
Direct Current ( DC ) : The direct current flows through a wire in one direction and it remains same over time. The current from battery is always direct current. Direc
