- a ship's total weight is equal to the weight of the water it displaces. if you want to calculate the
ship's weight, you must first know
a. the volume of water in the lake or ocean in which the ship is floating.
b. the volume of the entire ship.
c. the volume of the part of the ship that lies below the water's surface.
d. all of the above

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
