A drainage pipe running under a highway is 20 meters long. One end of the pipe is open and the other is clogged by debris. The wind blowing across the open end causes oscillations in the pipe.

a) If the speed of sound on that particular day is 340 meters per second, what will be the fundamental frequency of oscillation in the pipe?

b) What will be the frequency of the highest harmonic audible to the human ear. (Assume that human ears can hear frequencies up to 20,000 Hz)?
c) What will happen to the frequency in the late afternoon as the air begins to cool?

A very long pipe is capped at one end with a semipermeable membrane. How deep (in meters) must the pipe be immersed into the sea for fresh water to begin to pass through the membrane? Assume the water to be at 20.0°C and treat it as a 0.700 M NaCl solution. The density of seawater is 1.03 g/cm3 and the acceleration due to gravity is 9.81 m/s2.

A 0.726-kg rope 2.00 meters long lies on a floor. You grasp one end of the rope and begin lifting it upward with a constant speed of 0.710 m/s. Find the position and velocity of the rope’s center of mass from the time you begin lifting the rope to the time the last piece of rope lifts off the floor. Plot your results. (Assume the rope occupies negligible volume directly below the point where it is being lifted.)
