Find the linear speed of the bottom of a container that is set in a centrifuge if the centripetal acceleration there is 53,000 times the acceleration due to gravity. The distance from the axis of rotation to the bottom of the container is 8.5 cm.
*sig figs and units!
(hint: your final answer should be in km/s)

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
