A tube 1.27 meter long is closed at one end. A stretched wire is located near the open end. The wire is 0.400 meter long and has a mass of 8.80 gram. It is fixed at both ends and vibrates in its fundamental mode. By resonance, it sets the air column in the tube into oscillation at that column's fundamental frequency. Use 343 m/s for the speed of sound in air.
(a) Determine that frequency.
Hz
(b) Find what the tension in the wire.
