#8 -9 please assist with this problem as soon as possible. Thank you very much!
8. -/1.5 pointsWhat are the three lowest frequencies for standing waves on a wire 7.0 m long (fixed at both ends) having a mass of 170 g, which isstretched under a tension of 250 N?Hz (lowest)Hz (next lowest)Hz (3rd lowest)9. -/1 pointsA string is stretched between fixed supports separated by 77.5 m. It is observed to have resonant frequencies of 355.000 and 390.500Hz, and no other resonant frequencies between these two.Note: "Resonant frequency" is another term for harmonic frequency.(a) What is the lowest resonant frequency for this string?Hzb) What is the wave speed for this string?m/s
