A rubber ball is taken down to 100 metre deep lake and its volume decreases by 0.1%. If g = `10 m//s` what is the bulk modulus of rubber?

200 cm^3 of air is kept at 760 mm of mercury pressure. Keeping the temperature constant, if the pressure or that air is increased by 1mm of mercury, then its volume decreases by 0.263 cm^3 . Calculate the bulk modulus of air.

The volume of 1 litre of glycerine decrease by 0.42 cm^3 on application of a pressure of 20 kg.cm^-2 .Calculate the bulk modulus of glycerine.

A spherical ball contracts in volume by 0.01% when subjected to a normal uniform pressure of 100 atmospheres. The Bulk modulus of its material in dyne/ cm^2 is ( 1atm=1.01xx10^5N//m^2 ).

Volume of a substance at normal atmospheric pressure is 3500 times 10^-6 m^3 . What will be its change in volume at the pressure of 25 standard atmosphere? Given that bulk modulus of the substance is 10^11 N.m^-2 .

A rubber cord of length 10 m is suspended vertically. How much does it stretch under its own weight? Density of rubber =1.5 times 10^3 kg .m^-3 , Young's modulus of rubber =6 times 10^6 gf.cm^-2 , g= 9.8 m.s^-2

A rubber ball is thrown vertically downwards from the top of a tower with an initial velocity of 14"m.s"^(-1) . A second ball is dropped 1 s later from the same place. In 2 s the first ball reaches the ground and rebounds upwards with the same velocity. When will they collide with each other?
