About 675 MPh, 1,087 k/ph or 587 knots.
Yes, the speed of sound is generally slower at greater depths in water due to the increase in pressure and temperature. At 300 feet below sea level, the water is typically denser and warmer than at 200 feet, which can lead to variations in sound speed. However, the increase in pressure at greater depths can also affect sound speed. Ultimately, the specific conditions at those depths will determine the exact speed of sound.
The speed of sound in water is affected by temperature, salinity, pressure, and depth. Typically, the speed of sound increases with depth due to increased pressure, so it is likely louder at 300 feet below sea level compared to 200 feet.
about 1,115 feet per second, or 760 miles per hour, or 2,044,380 furlongs per fortnight
The Barrett M107 .50 caliber sniper rifle is known to shoot faster than the speed of sound. The speed of sound is approximately 1,125 feet per second, while the Barrett M107 has a muzzle velocity of about 2,800 feet per second.
The speed of sound in air at room temperature is approximately 343 meters per second. The closest thing to this speed that humans can achieve is the speed of a bullet fired from a high-powered rifle, which can travel at speeds up to around 1000 meters per second.
There are 5280 feet in one mile. Therefore, 100000 feet is equal to 100000/5280 = 18.93 recurring (that is, 18.939393...) miles.
1,100 feet per second
100000 feet is approximately 28333.3 yards
The speed of sound in water is affected by temperature, salinity, pressure, and depth. Typically, the speed of sound increases with depth due to increased pressure, so it is likely louder at 300 feet below sea level compared to 200 feet.
It depends on the aircraft's altitude. The speed of sound is decreasing as altitude increases, thus an airplane flying at the speed of sound at 1000 feet will be traveling as fast as 1200 kilometers per hour, while one flying at 30000 feet will be moving way slower, in the 800 kph range.
The speed of light is much faster than the speed of sound. Light travels at approximately 186,282 miles per second in a vacuum, while sound travels at about 1,125 feet per second in air.
about 1,115 feet per second, or 760 miles per hour, or 2,044,380 furlongs per fortnight
The round trip distance is 200 feet. The speed in this case is 200 / .185, or 1081 feet per second.
'Square feet' is a measure of AREA 'Miles' is a measure of LENGTH.
Sound is the closest to that figure. The speed of sound at sea level is ~1,116.44 feet per second.
Mach 100,000 is approximately 34,030,541.7 meters per second, or about 120,812,000 kilometers per hour. At this speed, an object would be traveling far faster than any known aircraft or spacecraft. It far exceeds the speed of any practical use for transportation on Earth.
