WebThe speed at which you break the sound barrier depends on many conditions, including weather and altitude. It's approximately 770 mph or 1,239 kmh at sea level. WebSince the speed of sound through the standard atmosphere is 761 mph (1,223 km/h) at sea level, Mach 2 then follows as 1,522 mph (2,447 km/h). If you were to ask how fast is Mach 2 at an altitude of 30,000 ft (9,150 m), we would use the same methodology to find out that it is only 1,356 mph (2,180 km/h) because the speed of sound generally ...

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by springs. In real material … See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the See more General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat … See more Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of stiffness in solids) is given by $${\displaystyle K=\gamma \cdot p.}$$ Thus, from the … See more WebThe speed of sound in air at 20 oC (293.15 K) and absolute pressure 1 bar can be calculated as c = (1.4 (286.9 J/K kg) (293.15 K))1/2 = 343.1 (m/s) Example - Speed of Sound in Water The speed of sound in water at 10 oC … kids vs grownups pictionary app
