You have a stopped pipe of adjustable length close to a taut 85.0cm, 7.25 g wire under a tension of 4030 N. You want to adjust the length of the pipe sothat, when it produces sound at its fundamental frequency, thissound causes the wire to vibrate in its second overtone with verylarge amplitude.

How long should the pipe be?

Sorry my friend i don't know the answer. i am just in 6th

Depotion can i think

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
