How long does it take sound to travel 100m?
about 0.29 second
How is a light year calculated?
A light year is a measurement for distance; It is calculated by multiplying the number of seconds in a year by the distance light travels in 1 second ( which is roughly 300,000 Km). So something like 300,000,000 * 60 * 60 * 24 * 365 = 1 lightyear in meters * 60 to get to minutes, again * 60 to get to hours, then * 24 to get to days and finally * 365 to get to the distance light travels in 1 year.
When lightning strikes 8 km away from you You hear the thunder about 24 seconds after the strike How long after the strike do you see the lightning?
The speed of sound with dry air at 20 °C (68 °F) is 343 meters / second. Performing some simple algebra 8 kilometers * 1000 meters / kilometer * 1 second / 343 meters = 23.32 seconds. So in this case, the air must be a different temperature or be denser due to more water vapor in the air. The speed of light in a vacuum is 299,792,458 meters / second. Performing some simple algebra. 8 kilometers * 1000 meters / kilometer * 1 second / 299,792,458 meters = 0.0000266 seconds.
If a cannon fires at a great distance from you why do you see the flash before you hear the sound?
Light travels much faster than sound. When a cannon fires, the light travels to your eyes almost instantly, allowing you to see the flash before the sound waves reach your ears. This creates a delay between what you see and what you hear.
How far is the Andromeda galaxy in meters?
The Andromeda galaxy is estimated to be over 2.7 million light years away. Light travels 299,792,458 meters per second. There are 31,536,000 seconds in one year. If 31,536,000 is multiplied by 2.7 million the answer is 8.51472 to the 13th power.
What is the speed of a rocket that travels 9000 meters in 12.12 seconds-?
A rocket that travels 9000 meters in 12.12 seconds moves at 742.5742 meters/second which is approx 1660 mph
Wave speed that travels 4 meters in 2 seconds?
4 meters/2 seconds = 2 meters/second.
A car travels 40 meters in 10 seconds Which is its speed?
40 meters/10 seconds = 4 meters per second.
What is the speed if something travels 200 meters in 25 seconds?
its speed =200/25 meters/second = 8 meters/second
What is the unit rate for meters per second if a car travels 399 meters in 19 seconds?
Just divide the distance (in meters) by the time (in seconds).
If sound travels 331 meters per second how many seconds to travel a kilometer?
distance = rate * time 1000 meters = 331 meters/second * x seconds x = 1000 / 331 So about 3 seconds.
What is the speed of an object that travels 100 meters in 50 seconds?
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
What is the average velocity of an object that travels 6 meters north in 2 seconds and then travels 3 meters east in 1 second?
3.00 m/s
What is the speed of a car that travels 200 meters in 25 seconds?
The speed of the car is 8 meters per second (200 meters / 25 seconds = 8 m/s).
What is the unit rate for meters per second if a car travels 437 meters in 23 seconds?
If you divide the distance by the time, you'll get the speed - in this case, in meters/second.
What is the speed of an object that travels 45 meters in 15 seconds?
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
What is the velocity of a car that travels -50 meters per second in 5 seconds then 10 meters in 5 seconds?
To find the average velocity of the car over the entire 10 seconds, we calculate the total displacement and divide it by the total time. The car travels -50 meters in the first 5 seconds and 10 meters in the next 5 seconds, resulting in a total displacement of -50 + 10 = -40 meters. The total time is 10 seconds. Therefore, the average velocity is -40 meters / 10 seconds = -4 meters per second.
