With explanation please and step-by-step solution. Thanks 2. What is the ratio of the velocity of sound in helium gas to that in air at the same pressure and temperature? On the basis of your answer, can you explain why you will sound funny if you happen to in helium gas and speak?
Examples 1. Find the Young' modulus for a bone if its 2. What is the ratio of the velocity of sound specific gravity is 2.0 and the velocity of sound in the bone is 2.8 x 103m/s. in helium gas to that in air at the same pressure and temperature? On the basis of your answer, can you explain why you will sound funny if you happen to helium gas and speak? in
Personalized lecules have twice the mass of hydrogen gas molecules (H2).A container of helium-4 gas and a container of hydrogen gas are at the same temperature. What is the ratio of the average speed of the helium molecules to the average speed of the hydrogen molecules? Enter your response Why? Comes from 13.4 Kinetic Theory: Atomic and Molecular Explanation of Pressure and Temperature
A device emits a sound wave in helium gas which then travels into standard air of the same temperature. If the speed of sound in helium is about three times the speed of sound in standard air, which of the following is true? The frequency of the sound is unchanged as the wave travels from helium to standard air while the wavelength increases. The frequency of sound decreases as the wave travels from helium to standard air while the wavelength...
At what temperature is the speed of sound in helium (ideal gas, = 1.67, atomic mass = 4.003 u) the same as its speed in oxygen gas at 19.0 oC? The speed of sound in oxygen at 19.0°C is 328 m/s.
At what temperature is the speed of sound in helium (ideal gas, = 1.67, atomic mass = 4.003 u) the same as its speed in oxygen gas at 15.9 oC? The speed of sound in oxygen at 15.9°C is 322 m/s.

If you have ever inhaled helium (a trick you should only do carefully) and then try to speak, you notice your voice sounds very different. (A) what is the speed of sound in helium? What is the ratio of that speed to the speed in air? (B) Assuming the wavelength is set by the person making the sound (whose internal dimensions set the boundary conditions) what is the ratio of the new pitch to the old pitch? (C) What fraction...
For fire safety considerations, there is a proposal to replace nitrogen with helium in air as the atmosphere of EVA operation in manned space vehicles. Compute the speed of sound for an atmosphere with 25% O2 and 75% He (volume or molar percentages) at a temperature of 15 C and 80 kPa pressure. Compare your answer with that of standard air in the same environmental conditions. (Hint: you need to determine both the molecular weight of the mixture and the...
Can I please get help wit this 5. The speed of sound in fresh water at 293 K is 1482 m/s. At what temperature is the speed of sound in helium gas the same as that of fresh water at 293 K? Helium is considered a monatomic ideal gas (Y 1.67 and atomic mass 4.003 u)
