The bulk modulus of steel is 1.6 X 101and the density of sea water is 1020 . Find the change in diameter of the sphere. Hint: The change in volume of a sphere is equivalent to a spherical shell. For a very small change, the volume of that spherical shell can be approximated as the surface area of the sphere times the thickness of the shell. frictionless bookend 3) Leaning Book A 5.00 cm tall book has a mass of 6.00 g that is uniformly distributed along its length. The book is on a shelf, and it leans against a frictionless bookend with the bottom of the book 3.00 cm from the bookend. Find the minimum coefficient of static friction between the book and the shelf such that the book does not slip. 5 cm
