1. Speed of Sound

   Speed of Sound is a song by British rock band Coldplay. It was written by all members of the band for their third studio album, X&Y (2005). Constructed around a piano and guitar riff, the song builds into a huge, synthesiser-heavy chorus. It was released by Parlophone Records as the lead single from the album. "Speed of Sound" was released in the US and UK on 18 April 2005, and then made its radio premiere on BBC Radio 1 with Lamacq on the day of the release on 19 April. The single was pressed with two B-sides: "Things I Don't Understand" and "Proof". The song premiered in the UK on 23 May. Coldplay vocalist Chris Martin admitted that the song was developed after the band had listened to English art rock singer Kate Bush. Upon the song's release, it charted in the UK Singles Chart in the number two position. In the United States, it debuted at number eight on the Billboard Hot 100, their first top ten hit in the country, and their most successful song until "Viva la Vida" reached number one in 2008.

1. Speed of sound

   The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C, the speed of sound is 343.2 metres per second. This is 1,236 kilometres per hour, or about one kilometer in three seconds or approximately one mile in five seconds. In fluid dynamics, the speed of sound in a fluid medium is used as a relative measure of speed itself. The speed of an object divided by the speed of sound in the fluid is called the Mach number. Objects moving at speeds greater than Mach1 are traveling at supersonic speeds. The speed of sound in an ideal gas is independent of frequency, but does vary slightly with frequency in a real gas. It is proportional to the square root of the absolute temperature, but is independent of pressure or density for a given ideal gas. Sound speed in air varies slightly with pressure only because air is not quite an ideal gas. In addition, for different gases, the speed of sound is inversely proportional to the mean molecular weight of the gas, and is affected to a lesser extent by the number of ways in which the molecules of the gas can store heat from compression, since sound in gases is a compression wave. Although the speed of sound is expressed in terms of a ratio of both density and pressure, these quantities cancel in ideal gases at any given temperature, composition, and heat capacity. This leads to a velocity formula for ideal gases which includes only the latter independent variables.

Examples of speed of sound in a Sentence

1. Mark Thomas:

   The biggest issue that the guys have had to wrestle with is how you cope with extremely high temperatures that come into the engine when you're doing hypersonic speeds; so more than five times the speed of sound, 4,000 miles-per-hour. The temperature coming in at the front of the engine is a thousand degrees centigrade. And you have to be able to cool that air very rapidly to be able to do anything useful with it.

2. Geoffrey Carter:

   The infrared looks for a flash from a gunshot and the acoustics listens for the bang, so we get the flash and the bang, and then we cue the operator. The accoustics get us very accurate azimuth, or bearing, to the threat. The combination of knowing the speed of light and the speed of sound, we’re able to get the distance in the time of arrival to the threat.
