Question 13 (0.00001 points) The speed of sound traveling through ocean water has been modeled by the equaon k S = 1440 + 4.5T 0.005T2 + 0.00031!\"3 + 0.0151) where Sis the speed of sound (in meters per second), T is the temperature (in degrees Celsius), and D is the depth below the ocean surface (in meters). A scuba diver began a dive into the ocean water. After 30 minutes, the diver is 10 meters below the ocean surface and the temperature is measured as 12 degrees Celsius. (a) What is the speed of sound at that moment? 1 (b) At the same moment, if the diver is descending at a rate of -- meters per secc 1 and the temperature is dropping at a rate of E degrees Celsius per second, whz the rate of change of the speed of sound? What are the units? (c) is the speed of sound increasing or decreasing
