37. A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross-section

A₁ and A₂ , are v₁ and v₂  The difference in the levels of the liquid in the two vertical tubes is h

(a) The volume of the liquid flowing through the tube in unit time is  A₁v₁

(b) v₂ – v₁ =√2gh

(c)  v₂ ² – v₁ ² =2gh

(d)  The energy per unit mass of the liquid is the same in both sections of the tube

Answer-a,c,d
