Question #103008

1.) A cello string vibrates in its fundamental

mode with a frequency of 179 1/s. The vibrating segment is 29.2 cm long and has a

mass of 0.75 g.

Find the tension in the string.

Answer in units of N

2).Find the frequency of the string when it

vibrates in seven segments.

Answer in units of 1/s.

Expert's answer

1)

"v=f\\lambda=2lf=\\sqrt{\\frac{Tl}{m}}""2(179)(0.292)=\\sqrt{\\frac{(0.292)T}{0.00075}}"

"T=28.1\\ N"
