The production of sound during speech or singing is a complicated process. Let's concentrate on the mouth. A typical depth for the human mouth is about 7.80 cm , although this number can vary. (Check it against your own mouth.). We can model the mouth as an organ pipe that is open at the back of the throat.
PART A: What are the wavelengths of the first four harmonics you can produce if your mouth is open?PART B: What are the frequencies of the first four harmonics you can produce if your mouth is open? Use 350 m/s.PART C:What are the wavelengths of the first four harmonics you can produce if your mouth is closed?PART D: What are the frequencies of the first four harmonics you can produce if your mouth is closed?
A 1,8000-kg SUV rounds a flay (unbanked) curve with a radius of 90m. the average coefficients of kinetic and static friction between the tire of the car and the road are static coefficient = 0.85, What is the maximun driving speed for the car

On a banked race track, the smallest circular path on which cars can move has a radius of 103 meter, while the largest has a radius of 165 meter. Determine the largest speed at which cars can move on this track without relying on friction
An object is placed to the left of a lens, and a real image is formed to the right of the lens. How far from the lens is the object
An old-style TV set places 50 kV across two plates of a parallel plate capacitor. An electron is released very close to one plate, find the speed of the electron when it exits the hole in the plate
A 3kilogram mass sliding on frictionless surface has a velocity of 5m/s east, Find how much kinetic energy does the two mass system lose during the collision

After sliding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.9 m/s. How fast do the two of them slide across the snow
The smallest object we can resolve with our eye is limited by the size of the light receptor cells in the retina. In order for us to distinguish any detail in an object, its image cannot be any smaller than a single retinal cell. Although the size..
