A cylindrical vessel contains a liquid of density `rho` up to height `h`. The liquid is closed by a piston of mass `m` and area of cross section `A`. There is a small hole at the bottom of the vessel. The speed `v` with which the liquid comes out of the hole is A. `sqrt(2gh)`B. `sqrt(2(gh+(mg)/(pA)))`C. `sqrt(2(gh+(mg)/(A)))`D. `sqrt(2gh+(mg)/(A))` |
