Forces exceeding those of earth's gravitational acceleration are important for astronauts, fighter pilots, and centrifugation to separate cells from a broth. estimate quantitatively the hydrostatic pressure (in units of atm) at the bottom of an open centrifuge tube that is 3 cm long, filled with water to a depth of 2 cm when held upright, and is spun in a laboratory centrifuge at 5000 rpm. assume the tube spins with its opening to the center of rotation, and the long axis of the tube at 90 degrees to the rotor axis of the centrifuge. the top of the centrifuge tube is 9 cm from the center of rotation. use the problem solving checklist. you may assume a single value of acceleration, justify your choice. look up how a laboratory centrifuge works, what the rotor is, and any other unknown items as needed.

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.
