Where $c$ is the speed of light, and $p$ and $\rho$ are the pressure and density of the gas. This creates oscillations, or sound waves with tremendously long wavelengths.

We assume you are converting between nautical mile/hour and speed of sound. But as a clump grows, pressure from baryons and photons increase, counteracting the collapse, and pushing baryons and photons outwards, while the dark matter tends to stay at the center of the overdensity, since it doesn't care about pressure. How many nautical mile per hour in 1 speed of sound The answer is 661.47084233261.

On a standard day at sea level static conditions, the speed of. An analysis based on conservation of mass and momentum shows that the speed of sound a is equal to the square root of the ratio of specific heats g times the gas. Stuff was still slightly clumpy, though, and the clumps grew in size due to gravity. The speed of sound through the atmosphere is a constant that depends on the daily temperature. The speed of sound is a constant within a given gas and the value of the constant depends on the type of gas (air, pure oxygen, carbon dioxide, etc.) and the temperature of the gas. Speed of sound in the primordial soupĮverything was very smooth, no galaxies or anything like that had formed. The photons themselves couldn't travel very far, before hitting a free electron. This temperature was so high, that neutral atoms couldn't form any electron caught by a proton would soon be knocked off by a photon (or another particle). they shared the same (average) energy per particle, or temperature. 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 2.9 s or one mile. So I will just add one further thought (in case it is of interest): You use the 'speed of sound in air. Therefore, 1 mile is equivalent to 1.609344 kilometers.By popular demand (considering two to be popular - thanks Vance and Learning), I'll expand a bit on my comment to Hunt's answer: Thermal equilibriumĪs I said in the comment, the notion of sound in space plays a very significant role in cosmology: When the Universe was very young, dark matter, normal ("baryonic") matter, and light (photons) was in thermal equilibrium, i.e. Answer (1 of 12): I see that many people have already answered. This is why we see it so much sooner than we hear. The linear equation above works well to approximate the SOS. The flash of light from lightning travels at about 300,000 kilometers per second or 186,000 miles per second. The units are defined as follows: An object moving at 1 "mph" per hour will cover a distance of one mile. Using this formula, the approximate speed of sound at 20° Celsius (68° Fahrenheit) is: 344 meters per second (m/s) 1128 feet per second (f/s) 770 miles per hour (mph) 1235 kilometers hour (kph) Use the calculator below to compute the approximate speed of sound at other temperatures. The length unit "mile" is commonly used in the Anglo-American countries, where speeds are represented in miles (instead of kilometers) per time unit and it should not be confused sea mile. mach (speed of sound) Ma second per mile. Imagine, if the start shot was fired at the finish line, it would take about 0.3 seconds of time to hear the shot in the start blocks. You are currently converting speed units from mach (speed of sound) to second per mile 1 Ma 4.7333647058824 sec/mile. Convert speed of sound (sea level) versus miles per second (mps) in swapped opposite direction. Another example, in a 100-meter sprint, the starting shot is fired directly next to the starting blocks. 1 speed of sound (sea level) 0.21 miles per second (mps) Filed under: Main menu speed and velocity menu Speed of sound conversion. It measures the number of miles traveled in a second.

The speed of sound is often illustrated by an example of a thunderstorm: if lightning strikes within 3 seconds of the thunder sound, then the thunderstorm is about 1 kilometer away. Miles per second is a unit of Speed or Velocity in both US Customary Units as well as the Imperial System. Actually, it is equivalent to 1.234,8 km/h. The speed of light in vacuum, commonly denoted c, is a universal physical constant that is important in many areas of physics.Its exact value is defined as 299 792 458 metres per second (approximately 300 000 km/s or 186 000 mi/s). Definition: If an object travels at the speed of sound in air at 20 degrees Celsius for one second, it travels a distance of 343 meters per second.
