The bulk modulus of a liquid is `2 xx 10^10 N/m^2`. What is the percentage decrease in the volume of the liquid , when the pressure is increased by 20 atmosphere > ( one atmosphere = `10^5 N /m^2`).

Bulk modulus of water is 2 xx 10^9 N/m^2 . What pressure is required to reduce a given volume of water by 1 percent ?

Due to a stress of 20 N/ m^2 the percentage increase in the length of a wire is 0.01. calculate the young's modulus.

The young's modulus of a wire of length 2m and area of cross section 1mm^2 is 2 xx 10^10 N/m^2 . What is the work done in increasing it's length by 2mm.

Find the velocity of a liquid density 800kg//m^3 from a tank in which the pressure of the liquid at the orifice is 480 N//m^3 above the atmospheric pressure.

A water drop has a diameter of 2 xx 10^-5m . Calculate the excess pressure inside, compared to the outside, if the surface tension of water is 0.072 N/m

A fog drop has a diameter of 2xx10^-6 m. Calculate the pressure inside the drop in atmospheres , if the temperature is 20^@ C. Assume the air pressure outside the drop one atmosphere and surface tension of water=0.0727N/m (1atm=1.013xx10^5N/m^2) .
