1.
Equal masses of water and liquid are mixed together, 6.then the mixture has a density of:
2.
Two stretched membranes of area 2 cm2 and 3 cm2 areplaced in a liquid at the same depth. The ratio of thepressures on them are :
3.
A cylindrical vessel containing a liquid is closed by asmooth piston of mass m. If A is the cross-sectional areaof the piston and P0 is the atmospheric pressure, then the gpressure of the liquid just below the piston is :
4.
An iceberg is floating partially immersed in sea watei. Ifthe density of sea water is 1.03 g/cc and that of ice is0.92 g/cc, the fraction of the total volume of icebergabove the level of sea water is:
5.
A piece of solid weighs 120 g in air, 80 g in water and60 g in a liquid, then the relative density of the solid andthat of liquid are respectively :3
