Infra sounds are sounds with frequencies below 20 Hz.The popular concept that infra sounds are in audible holds false
Explanation:
- Some example of Infrasounds are- some animals such as whales, elephants and giraffes which communicate with each other using infrasound over long distances.
- Various natural phenomenon such as Avalanches, volcanoes, earthquakes, ocean waves, water falls and meteors also generate infrasonic waves
- Infrasound, is sound that is lower in frequency than 20 Hz or cycles per second.
- Even the human body can generate mechanical vibrations at very low frequencies, which are known as the infrasonic waves. Such low-frequency vibrations/infrasonic waves are produced by physiological processes—such as heartbeats, respiratory movements, blood flow in vessels, and other processes.

Answer:
The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.
Explanation:
The kinetic energy of gas molecule is given by following equation:
Since the temperature (T) is constant for both molecules. Therefore, there kinetic energies will also be the same. Therefore,
<u>The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.</u>
