9. Question

The bulk modulus of a fluid is inversely proportional to the

10. Question

A solid sphere of radius R made of a material of bulk modulus K is completely immersed in a liquid in a cylindrical container. A mass less piston of area A floats on the surface of the liquid. When a mass M is placed on the piston to compress the liquid, the fractional change in the radius of the sphere,dR/R  is given by
