1.	A body is moving unidirectionally under the influence of a source of constant power supplying energy . Which of the diagram shown infigure correctly shownthe displacement time curve for its motion ?
Answer» SOLUTION :GIVEN Power , P = `(dW)/(DT)` ` = (F.DX)/(dt) ""( :. dW = FDX)` ` = ("Fdx")/(dt)` = constant ` ( :. " P = constant given")` Thus ,P = `FV ""( :. V = (dx)/(dt))` [F] [V] = constant ` :. [MLT^(-1)[ [LT^(-1)] ` = constant ` :. L^(2) T^(-3) = ` constant`( :. "mass is constant") ` ` :. L prop T^(3/2) rArr"Displacement " (d) prop t^(3/2)`
