A closed tube of length 0.60 m is used to create a standing sound wave. Assume that the standing wave created in the tube has the second longest wavelength possible (out of all possible standing waves that fit in the tube). If this tube is then placed on a truck that moves away (at a speed of 90.0 km/hr) from a stationary observer, what frequency does the observer hear?

he 22 In Fig. 17-38, sound with a s 40.0 cm wavelength travels right ve ward from a source and through a x.1 tube that consists of a straight por- tion and a half-circle. Part of the sound wave travels through the half- circle and then rejoins the rest of the wave, which goes directly through the straight portion. This rejoining results in interference.

2) Hot air enters a heat exchanger at 350°C and exits at 155°C. The heat extracted is used to boil 0.283 kg/s of 100°C water (from saturated liquid to saturated steam). The heat exchanger is a single-shell shell-and-tube heat exchanger with two tube passes. The overall heat transfer coefficient for the hot side is 240 W/(m²°C). Assume a constant specific heat for air of Cp = 1.005 kJ/(kg °C). The pressure of the hot air and the boiling water is...

EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a known...
