You work in a materials testing lab and your boss tells you to increase the temperature of a sample by 48.7%u2218C . The only thermometer you can find at your workbench reads in degrees Fahrenheit.
PART A) If the initial temperature of the sample is 67.8%u2218F, what is its temperature in degrees Fahrenheit when the desired temperature increase has been achieved?
Two steel guitar strings have the same length. String A has a diameter of 0.59 mm and is under 450.0 N of tension. String B has a diameter of 1.2 mm and is under a tension of 800.0 N. Find the ratio of the wave speeds, va/vb, in these two strings.
