If a wave travels at 8.7 m/s on a string with linear mass density 5.4 kg/m what is the tension in the string? Enter your answer to two decimal places and in standard units 3. On a 3.5 m string, we find that the wave speed is 209.2 m/s when a tension of 1746.9 N is applied. What is the mass of the string? Enter your answer in grams to zero decimal places. 3. A note with a frequency of 703 Hz is playing over a speaker. If you are in your car driving along and you hear the note as having 795 Hz, in which direction are you travelling
