Supersonic aircraft fly at speeds greater than the speed of sound, known as Mach 1. This speed varies depending on altitude and atmospheric conditions but is approximately 343 meters per second at sea level. These aircraft can travel faster than ...

The velocity of sound in air increases with increasing temperature. This is because warmer air has more energy, causing air molecules to move faster and transmit sound waves more quickly.
Sound waves travel fastest in solids due to the dense molecular structure that allows efficient transmission of vibrations. In liquids, sound travels slower than in solids, and it is slowest in gases due to their sparse molecular arrangement. Sound cannot ...
The speed of sound in air at room temperature (20°C) is approximately 343 meters per second. Among the given options, the closest approximation is 330 meters per second. This speed can vary slightly with changes in temperature and atmospheric conditions.
Explosions are not heard on the Moon away from the surface Due to the absence of atmosphere. Sound requires a medium like air to propagate, and the Moon’s vacuum-like environment lacks air molecules necessary to transmit sound waves. Therefore, no ...
