Mach 0.5 means that the object is travelling at half the speed of sound.
The speed of sound describes how far this wave travels in a given amount of time. In dry air at 20 °C (68 °F), the speed of sound is 343 meters per second (1,125 ft/s)zperiodz This equates to 1,236 kilometers per hour (768 mph), or about one kilometre in three seconds and about one mile in five seconds
Ernst Mach .
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
Mach 0.8 = about 593.2 mph
Mach 6 is about 4,449.3 mph
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
In the Dholuo language of African origin, "otit mach" has the meaning of "Firefly."
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
Maybe you mean Mach 1 - which is the speed of sound. Mach 2 is twice the speed of sound, and so on ...
I make/do my thing
Do you mean Mach 1? Speed of sound.
2283.6211 miles per hour is considered as mach 3. To be able to reach Mach 1 is to go 761.207 miles per hour. It is used to measure the speed of aircraft and rocketry.
It means 3.2 times the speed of sound.
I think you mean Mach' Dir keine Sorgen über all dies which translates as Don't worry about all of this
The original was "Bück dich, ich mach dich glücklich." i think. "Bück" not "Buch" ;) Did u?! ;)
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
