The straight lines in the figure depict the variations in temperature DeltaT as a function of the amount of heat supplied Q is different process involving the change of state of a monoatomic and a diatomic ideal gas . The initial states, ( P,V,T ) of the two gases are the same . Match the processes as described, with the straight lines in the graph as numbered. {:(,"Column-I",,"Column-II"),((A),"Isobaric process of monoatomic gas." ,(p),"1" ),((B),"Isobaric process of diatomic gas" ,(q),"2" ),((C),"Isochoric process of monoatomic gas" ,(r),"Minimum at section B"), ((D),"Isochoric process of diatomic gas" ,(s),"x-axis (i.e.'Q' axis)"):}

A block is placed on a horizontal table which can rotate about its axis.The block is placed at certain distance from centre as shown in figure. Table rotates such that particle does not slide. See possible direction of net acceleration of block at the instant shown in figure {:(,"Column-I","Column-II"),(,(A)"When rotation is clockwise with constant "omega,(P)1),(,(B)"When rotation is clock wise with decreasing "omega,(Q)2),(,(C)"When rotation is clockwise with increasing "omega,(R)3),(,(D)"Just after clockwise rotation beings from rest",(S)4):}

The equation of one dimensional motion of the particle is described in column I. At t=0 , particle is at origin and at rest.
