Nothing on that list of choices is a requirement.
The approximate speed of sound is about 761 mph or 335.28 meters/second.
<h3>What's the approximate speed of sound?</h3>
If we consider the normal atmosphere at sea level, the speed of sound is about 761 mph or 335.28 meters/second. The speed of sound is different in different mediums such as solid and liquid.
So we can conclude that the approximate speed of sound is about 761 mph or 335.28 meters/second.

Answer:
Kinetic friction is lesser than limiting friction. Two surfaces are rubbed together, first with a smaller force and then with a greater force.
Answer:
The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. ... The attenuation of sound in air is affected by the relative humidity. Dry air absorbs far more acoustical energy than does moist air.
