An iron cube of side 10 cm is kept on a horizontal table. If density of iron is `8000 kgm^-3`, find the pressure on the portion of the table, where the cube is ekpt `(g = 10ms^-2)`

A rectangular container, whose base is a square of side 5 cm, stands on a horizontal table, and holds water up to 1 cm from the top. When a cube is placed in the water it is completely submerged, the water rises to the top and 2 cubic cm of water overflows. Calculate the volume of the cube and also the length of its edge.

A metal cuboid of mass 'M' kg rests on a table with surface are of 40cm^2 in contact with the table. The pressure exerted by the cuboid on the table surface is 10000 Pa. Value of m is (given that g = 10ms^-2)

Glycerine flows steadily through a horizontal tube of length 1.5 m and radius 1.0 cm. If the amount of glycerine collected per second at one end is 4.0xx 10^-3 kg s^-1 , what is the pressure difference between the two ends of the tube ? (Density of glycerine = 1.3xx 10^3 kg m^-3 and viscosity of glycerine = 0.83 Pa s). [You may also like to check if the assumption of laminar flow in the tube is correct].
