The initial volume is Vi
The change in volume is
The final volume is
The bulk modulus is defined as:
Solve for :
Substitute numerical values:
Two racquetballs, each having a mass of 170 g, are placed in a glass jar as shown in Figure P12.59. Their centers lie on a straight line that makes a angle with the horizontal.
(a) Assume the walls are frictionless and determine .
(b) Determine the magnitude of the force exerted by the left ball on the right ball..
In the cabin of a ship, a soda can rests in a saucer-shaped indentation in a built-in counter. The can tilts as the ship slowly rolls. In which case is the can most stable against tipping over? (a) It is most stable when it is full. (b) It is most stable when it is half full. (c) It is most stable when it is empty. (d) It is most stable in two of these cases. (e) It is equally stable in all cases.
The deepest point in the ocean is in the Mariana Trench, about 11 km deep, in the Pacific. The pressure at this depth is huge, about 1.13 3 108 N/m2.
(a) Calculate the change in volume of 1.00 m3 of seawater carried from the surface to this deepest point.
(b) The density of seawater at the surface is 1.03 3 103 kg/m3. Find its density at the bottom.
(c) Explain whether or when it is a good approximation to think of water as incompressible.
