The first and second formants when you make an "ee" vowel sound are approximately 270 Hz and 2300 Hz . The speed of sound in your vocal tract is approximately 350 m/s . If you breathe a mix of oxygen and helium (as deep-sea divers often do), the speed increases to 810m/s

With this mix of gases, what are the frequencies of the two formants?

Expert Solution

Wavelength will remain same, just medium has changed from air to mixture of gases (air & helium).

For first formant,

λ = v1/f1 = v2/f2 350/270= 810/ f = 625 Hz

For second formant, 350/2300 = 810/f f = 5323 Hz

When the bell in a clock tower rings with a sound of 500 Hz, a pigeon roosting in the belfry flies directly away from the bell. If the pigeon hears a frequency of 450 Hz, what is its speed?

You never get a second chance to make a first impression. Thus, it is critical that you always be your best self to make a good first impression.

1. You never get a second chance to make a first impression. Thus, it is critical that you always be your best self to make a good first impression. Write at least one paragraph (5-6 sentences each) explaining why in your words and your own experience.2. In another paragraph, list three important things that you need to pay special attention to in order to make the most positive visual impact. Write at least 2-3 sentences on each explaining why they...

The speed of sound in seawater is approximately 1480 m/s. You are at a depth of 50.0m a. You ping the ocean bottom and receive the echo back 0.125 seconds later. How deep is the ocean at this point? b. If the frequency of the sound is 500.0 Hz, what is the wavelength of the sound? c. The ping coming back to the submarine has an intensity of as -80.0 dB. What is the intensity of the returning sound wave?...

A siren emitting a sound of frequency 1100 Hz moves away from you toward the face of a cliff at a speed of 15 m/s. Take the speed of sound in air as 330 m/s. (a) What is the frequency of the sound you hear coming directly from the siren? (Give your answer to at least one decimal place.) Hz (b) What is the frequency of the sound you hear reflected off the cliff? (Give your answer to at least...

A musician is tuning the pitch of a violin using a sound fork at 3,000 Hz. He first hears the combined sound intensity rise and fall with a time of 0.25 s between the maximum intensity and the succeeding minimum intensity.

A musician is tuning the pitch of a violin using a sound fork at 3,000 Hz. He first hears the combined sound intensity rise and fall with a time of 0.25 s between the maximum intensity and the succeeding minimum intensity. As he tightens the string, the time between the intensity maximums becomes longer. What is the pitch of the violin string at first?

In this second case you will modify the simulation to make it more realistic. In the natural environment, not all genotypes have the same rate of survival; that is, the environment might favor some genotypes while selecting against others. An example is the human condition sickle-cell anemia. It is a condition caused by a mutation on one allele, in which a homozygous recessive does not survive to reproduce. For this simulation you will assume that the homozygous recessive (ff) individuals...

Part D When solving problems involving stoichiometric coefficients, the first step is to make sure you have a balanced chemical equation. Then, you determine the limiting reagent by using the coefficients from the balanced equation. You can keep track of the amounts of all reactant and products before and after a reaction using an ICF table. Completing the ICF table will also allow you to determine the limiting reagent, and the amount of product formed assumes that the reaction runs...
