From given v-t graph identify correct a-t graph

Show that if the room temperature changes by a small amount from T to T +/_\T , the fundamental frequency of an organ pipe changes from v to v + /_\v, where (/_\v)/v=1/2(/_\T)/T .

If velocity v varies with time t as v=2t^(2) , then the plot between v and t^(2) will be given as :

If velocity v varies with time(t) as v=2t-3 , then the plot between v and t is best represented by :

Displacement x at time t is x=t-t^(3) . If v is the velocity and a the acceleration at time t, then :v =

The velocity v of a body moving along a straight line varies with time t as v=2t^(2)e^(-t) , where v is in m/s and t is in second. The acceleration of body is zero at t =
