Given: The bulk modulus this metal is B = 1.9 × 1011 N/m2 . Atmospheric pressure is Patm = 101300 Pa. At the earth’s surface, the pressure is ∆P = −1.0574 × 1010 Pa lower than at a depth of d = 311 km. If a cubic centimeter block of a metal were brought to the surface from this depth, what would be its new volume?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
