What else can I help you with?
Clare sees a lightning flash and counts 10 seconds before hearing its thunderclap If the speed of sound in air at sea level is about 730 miles per hour how far away is the lightning?
The speed of sound is approximately 1,125 feet per second (fps). Since Clare counted 10 seconds between the flash and the thunder, the lightning strike is approximately 11,250 feet away. This is equal to about 2.13 miles.
How much time does it take thunder to get to you from a lightning strike 5 miles away?
About 25 seconds. It's closer to 23, but 5 seconds per mile is the general rule of thumb.
Does light wave travel through air at a faster speed than sound?
Yes! Sound has to have a medium such as air to travel. That's why there is no sound in space. So, if you stood on the surface of the earth and yelled very loudly straight up, the sound would stop after about 300 miles, because our atmosphere is only 300 miles thick. When the air runs out, the sound stops. BUT, if you shine a very bright light straight up, the light could go much, much further, because light CAN travel through the vacuum of space. That's how we can see stars that are trillions of miles away, because of the light they shine in our direction.
When we say that the sound travels in air at a speed of 332ms what we meant that?
"ms" in this case is short for "meters per second". It means that sound advances that many meters every second.
How far is lightning when you hear thunder?
Sound travels through air at "the speed of sound." Officially, the speed of sound is 331.3 meters per second(1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second. 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. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.
You hear thunder 13.9 seconds after a lightning flash how far are you from lightning?
You are approximately 2.7 kilometers (1.7 miles) away from the lightning strike. Sound travels at about 343 meters per second, so by dividing the time gap of 13.9 seconds by the speed of sound, you can calculate the distance.
Where would you be34 hours from earth at light speed?
well the speed of light is roughly 186000 miles/second so you would be about 22766400000 miles away
Does light or sound travel faster in air?
Light travels almost a million times faster in air. There is very little difference between the speed of light in a vacuum as in air. It is around 0.01% slower in air. Because of the difference between the speed of light and sound you can estimate the distance of a lightning strike. For every 3 seconds between the flash and the sound of thunder the lightning strike is 1 km away or 5 seconds for a mile. The actual speeds are light 300,000 km per second speed of sound 0.33 km per second.
If a thunderstorm is 10 kilometers away How long does it take for the sound to reach you after you see the lightning?
Just under 30 seconds. The speed of sound in air is 1100 feet per second. To cover 10K (which is 6.2 miles), you could multiply 6.2 by 5,280 (the number of feet in a mile), which gives you 32,736 ft. Then divide the number of feet by the speed of sound, and you get 29.76 seconds. Roughly converted the speed of sound is 330 meters per second so it takes 3 second per kilometer, so 30 seconds

A soldier hears the sound of a distant cannon 6 seconds after he sees the flash How far away is the cannon?
Using the speed of sound at 20° C, which is 343 m/sec, the cannon would be 2058 meters away. Temperature, pressure, and humidity could all affect the actual speed.

Kira jogs to a store 72miles away in a time of 36 second . What is Kira's average speed?
To find Kira's average speed, you need to divide the total distance by the time taken: Speed = Distance/Time. In this case, Kira's average speed would be 72 miles divided by 36 seconds, which equals 2 miles per second.
If you hear thunder 3 seconds after you see lightning and sound travels at a speed of 330 meters per second the how far away is the storm?
The time difference between seeing lightning and hearing thunder is due to the difference in the speed of light and sound. Since sound travels at 330 meters per second, if you hear thunder 3 seconds after seeing lightning, the storm is approximately 990 meters away.
What sound waves are created when you travel faster than the speed of sound?
Supersonic waves are created when something surpasses the speed of sound, which ranges from 330-350 meters per second (depending on the temperature of the media, etc.) and the loud crack is called a sonic boom. The sonic boom isn't necessarily at the same time that the object breaks the barrier but when the sound wave reaches ones ears. Many sonic booms can be heard from miles away.
