A plastic box has an initial volume of 3.50 m 3 . It is then submerged below the surface of a liquid and its volume decreases to 3.48 m 3 .
-Complete the following statement: In order to calculate the "stress" on the box, in addition to the information given, one must also know
A)the mass of the box.
B)the bulk modulus of the material from which the box is made.
C)the shear modulus of the material from which the box is made.
D)the Young's modulus of the material from which the box is made.
E)the bulk modulus of the liquid.

The stress on the box is given by the formula stress =change in volume/initial volume * bulk modulus. Since the bulk modulus of the material from which the box is made is required in this formula, option B is the correct choice. Mass of the box, shear modulus, Young's modulus or bulk modulus of the liquid are not required to calculate the stress on the box.
