### Top 10 Snippets for:- “What is the speed of sound”

1.**What is the speed of sound**

If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second . We can use this knowledge to approximately determine how far away a lightning strike has occurred.

2.**What is the speed of sound**

At sea level, at a temperature of 21 degrees Celsius (70 degrees Fahrenheit) and under normal atmospheric conditions, the speed of sound is 344 m/s (1238 km/h or 770 mph). The speed varies…

3.**What is the speed of sound**

Here is a plot of the speed of sound at different heights above sea level. At sea level, the value is right around the 340 m/s mark. If you move up to 120,000 feet, the speed will drop down to…

4.**What is the speed of sound**

The speed of “sound” is actually the speed of transmission of a small disturbance through a medium. Sound itself is a sensation created in the human brain in response to sensory inputs from the inner ear. (We won’t comment on the old “tree falling in a forest” discussion!)

5.**What is the speed of sound**

speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second. The speed of sound in liquid water at 8 °C (46 °F) is about 1,439 metres (4,721 feet) per second.

6.**What is the speed of sound**

average speed = distance travelled ÷ time taken = 3.4 ÷ 0.01 = 340 m/s Sound through different materials Sound travels faster through liquids and solids than it does through air and other gases….

7.**What is the speed of sound**

The speed of sound is 767mph and anything above that is judged to be “supersonic”. London to New York in 2 hours; FANCY A DAY TRIP ACROSS THE ATLANTIC? Hypersonic jet could travel at 3900mph The turbo jets will help it get to the speed of sound and then retract, allowing the rocket motor to power it to more than 100,000 feet in the air.

8.**What is the speed of sound**

The speed of sound depends on the state of the gas–more specifically, the square root of the temperature of the gas. The speed of sound (a) is equal to the square root of the ratio of specific heats (g) times the gas constant (R) times the absolute temperature (T). a = sqrt [g * R * T] The derivation of this equation is given on a separate page.

9.**What is the speed of sound**

Answer (1 of 35): The speed of sound is not always the same. Remember that sound is a vibration of kinetic energy passed from molecule to molecule. The closer the molecules are to each other and the tighter their bonds, the less time it takes for them to pass the sound to each other and the faste…

10.**What is the speed of sound**

In 20 °C (68 °F) air at sea level, the speed of sound is approximately 343 m/s (1,230 km/h; 767 mph) using the formula v [m/s] = 331 + 0.6 T [°C].
