is the symbol for the speed of light, which equal to approximately 300000 kilometers per second. (300000000 meters per second).
is now calculated: (
)
, 
- Mach number, dimensionless.
- Speed of sound in air, measured in meters per second.
and 
, then the speed of the supersonic airplane is:
- Speed, measured in meters per second.
- Travelled distance, measured in meters.
- Time, measured in seconds.
and 
, then speed of the electron is:
, 
and 
, then speed of the electron is:
