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)

A open ended mercury manometer is used to measure the pressure exerted by a trapped gas as shown in the figure. Initially manometer shows no difference in mercury level in both columns as shown in diagram. After sparking 'A' dissociates according to following reaction 2A(g)rarr 3B(g)+2C(g) If pressure of Gas "A" dissociates to 0.8 atm, then (Assume temperature to be constant and is 300 K)

At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is 100 m^3s^-1 . If the turbine generator efficiency is 60%, estimate the electric power available from the plant (g = 9.8 ms^-2) .

What is the absolute and gauge pressure of the gas above the liquid surface in the tank shown in the following figure? Density of oil = 820 kg m^-3 , density of mercury = 13.6 xx 10^3 kg m^-3 , 1 atmosphere pressure = 1.01 xx 10^5 pa .
