Violin's A-string is tuned to 440 Hz and its linear density is 7.2 x 10 kg/m. If the length of the string in vibration (measured from the upper end of the fingerboard to the bridge, both ends are fixed.) is 33 cm, 15. What is the tension in the A-string? 16. What must the linear density of D-string (297 Hz) be so that the tension is the same as A-string? 17. The sound level at a distance of 3.00 m from a source is 120 dB. At what distance is the sound level 80 dB? GDAE
