a)The vibrating string length for a cello is 70 cm. If you hang a 17.7 kg mass from a cello A-string (see image) it gives the correct tension to produce a fundamental pitch of 220 Hz. What is the mass per unit length of a cello's A-string b) Consider an organ pipe 1.72 m long that has one open and one closed end. What is the fundamental pitch of this pipe? Draw a graph of pressure vs. position inside the ning when the air in this pine ir reconating at 150 HT
