Shown in the picture below is an empty CocaCola bottle. The height of the bottle is L = 0.195 meters. It is open at the top and closed at the bottom. For this problem, please use the velocity of sound in air as Vsound = 346.8 meters/second. L Determine all the following: The frequency produced when you blow across the top of the CocaCola bottle, fyou = Your friend decides to play along with you using an identical bottle. Unfortunately, your friend did not finish their coke and has left 0.009 meters of liquid in the bottom of the bottle. What frequency does your friend produce, ffriend = Hz What is the beat frequency heard when both bottles are "played" at once, fbeat = NOTE: Beat frequency is always a positive number.

Due to efficiency considerations related to its bow wake, the supersonic transport aircraft must maintain a cruising speed that is a constant ratio to the speed of sound (a constant Mach number). If the aircraft flies from warm air into colder air, should it increase or decrease its speed? Explain your answer.
Ultrasonic sound waves are often used in methods of nondestructive testing. For example, this method can be used to find structural faults in a steel I-beams used in building. Consider a 10.00 meter long, steel I-beam with a cross-section shown below. The weight of the I-beam is 3846.50 N. What would be the speed of sound through in the I-beam? (Ysteel=200GPa,steel=159GPa) .
When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.
The frequency of the siren of an ambulance is 900 Hz and is approaching you. You are standing on a corner and observe a frequency of 960 Hz. What is the speed of the ambulance (in mph) if the speed of sound is v=340.00 m/s?

During a 4th of July celebration, an M80 firework explodes on the ground, producing a bright flash and a loud bang. The air temperature of the night air is TF=90.00F . Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.00 second. The second observer notes the difference as 3.00 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance x between the two observers?
