Speed of sound can be abbreviated assound; for example, 1 speed of sound can be written as 1 sound. Learn more about thespeed of sound. What Is Mach Number? Mach, sometimes also referred to as a Mach number, is the ratio of the speed of an object to thespeed of sound.[2] ...
结果1 题目. MACH NUMBERS Ernst Mach (1838-1916) was an Aus-trian physicist who made a study of the motion of objectsat high speeds. Today we often state the speed of aircraftin terms of a Mach number. A Mach number is the speedof an object divided by the speed of sound. For ...
Speed is a vector quantity, as it has both a magnitude (the speed) and a direction.Converter You are currently converting speed units from mach (speed of sound) to minute per mile 1 Ma = 0.078889411764706 min/mile mach (speed of sound) Ma minute per mile 0.078889411764706 min/mile...
When twice the speed of sound, it is Mach 2. When it is near but below the speed of sound, its speed can be designated at less than Mach 1. for example, Mach 90. Mach is defined as "the ratio of the velocity of a rocket or a jet to the velocity of sound in the medium being...

the speed of sound is 340.3m/s(1225km/h, or 761.2mph, or 1116ft/s) in theEarth's atmosphere. The speed represented by Mach 1 is not a constant; for example, it is dependent on temperature and atmospheric composition. In thestratosphereit remains constant irrespective of altitude even thou...
Mach Number (M) = Speed of Object (V) / Speed of Sound (a) For example, if an aircraft is flying at a speed equal to the speed of sound, its Mach number would be 1.0 (Mach 1). If it is flying at twice the speed of sound, its Mach number would be 2.0 (Mach 2), and so...
