What is speed of sound in KM?

What is speed of sound in KM?

The velocity of sound in air at 20oC is 343.2 m/s which translates to 1,236 km/h.

Is the speed of sound 1000 mph?

The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h).

What is the speed of sound at 60000 feet?

Speed of Sound at a known temperature and density of air

Altitude	Speed of Sound
Feet (ft)	Meter (m)	mph
50,000	15240	659.8
55,000	16764	659.8
60,000	18288	659.8

Why is the speed of sound 330m s?

If a sound wave were observed to travel a distance of 700 meters in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance – perhaps 660 meters – in the same time period of 2 seconds and thus have a speed of 330 m/s.

How far can humans hear in KM?

The normal intelligible outdoor range of the male human voice in still air is 180 m (590 ft 6.6 in). The silbo, the whistled language of the Spanish-speaking inhabitants of the Canary Island of La Gomera, is intelligible under ideal conditions at 8 km (5 miles).

How fast is sound in water?

Sound travels faster in water than in air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about 1,480 meters per second. Fundamentally, standard sound is a compression wave traveling though a material.

What is the fastest sound ever?

Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter — for instance, they travel faster in warmer liquids compared with colder ones.

How fast is light years in mph?

How far is a light-year? The speed of light is constant throughout the universe and is known to high precision. In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766).

Has any car hit the speed of sound?

Thrust SSC holds the world land speed record, set on 15 October 1997, and driven by Andy Green, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.

What is the fastest plane?

The fastest known jet aircraft – military or civilian It’s the Lockheed SR-71 Blackbird – an American high-altitude reconnaissance airplane intended to outrun surface-to-air missiles and interceptors.

What is the fastest plane in the world?

The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

What limits sound speed?

Sound is a wave that propagates by making neighbouring particles interact with one another, so its speed depends on the density of a material and how the atoms within it are bound together. Atoms can only move so quickly, and the speed of sound is limited by that movement.

Is light 300 times faster than sound?

The speed of light is much faster than the speed of sound in air. If you want to compare, the speed of sound in air is ~ 343 m/s and the speed of light is 3×1010 m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile.

Why is breaking speed of sound so loud?

Numerous pressure waves combine together to form a single shock wave. They have the ability to move faster than the speed of sound. The constant expansion and contraction of air can cause a shock wave that sounds like a loud clap to human ears. This is why a sonic boom can be so loud.

Did Einstein know speed of sound?

Albert Einstein was once asked: “What is the speed of sound?” Without batting an eye he answered cheerfully: “I don’t know. I don’t burden my memory with such facts that I can easily find in any textbook.” Well, what is good enough as a reply for the greatest living scientist is good enough for us.

How far can a dog smell?

If more air passes through their nose they have more chance to pick up smells. How far dogs can smell depends on many things, such as the wind and the type of scent. Under perfect conditions, they have been reported to smell objects or people as far as 20km away.

How far can dogs hear?

Although those are some of the dog breeds that have the best sense of hearing, all dogs can hear very well—much better than any human can. Regardless of the dog breed they belong to, most dogs can hear sounds anywhere between 80 feet and one mile away.

How far can a scream be heard?

On Earth, the sound from an average scream might travel about three-quarters of a mile, depending on conditions.

What is the speed of sound at 10 km?

The speed of sound at an altitude of 10 km (the height at which most jumbo jets fly) is approximately 295 m/s.

How long does it take sound to go 1 km?

As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

How fast is Mach 1 in kmph?

Mach to Kilometers per hour table

Mach	Kilometers per hour
1 Mach	1225.04 kph
2 Mach	2450.09 kph
3 Mach	3675.13 kph
4 Mach	4900.18 kph

What is the speed of sound in meters?

At 0° Centigrade and 1.013 x 105 Newtons per square meter (normal atmospheric pressure), the speed of sound is 331.5 meters/sec, i.e. 1087 ft/sec or 740 miles/hour. At 20°C (68°F) the speed is 1130 ft/sec or 344 m/sec.
