Aclamped 24 cm wire with 25 g/m mass density vibrates at its fundamental mode near an 85 cm long open/closed tube. the wire vibration excites the second harmonic of the tube. what is the tension in the wire in n?

T = 518.4 N

Explanation:

Length of wire,l = 24 cm = 0.24 m

mass density of wire,μ = 25 g/m = 0.025 g/m

Length of the tube, L = 85 cm = 0.85 m

speed of sound, v = 340 m/s

frequency in the tube in open/closed tube

now, calculation of tension in the wire.

Frequency in the wire will be same as frequency in the tube

now,

squaring both side and arranging

     T = 518.4 N

hence, the tension in wire is equal to T = 518.4 N

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
