An iron spherical ball of volume 232848 `cm^3` has been melted and converted into a cone wih the vertical angle of `120^(@)`. What are its height and base?

A spherical ball of volume 1000 cm^3 is subjected to a pressure of 10 atmosphere. The change in volume is 10^(-2)cm^3 . If the ball is made of iron find its bulk modulus, (Atmospheric pressure = 1xx10^5 Nm^(-2) )

A spherical ball of volume 1000cm^(3) is subjected to a presure of 10 atmosphere. The change in volume is 10^(-8cm^(3). If the ball is made of iron, find its bulk modulus. ("1 atmoshphere"=1xx10^(5)Nm^(-2)).
