What speed does light travel as it moves through glass with an index of refraction n equals 4.5?
It will travel with speed about 0.844 meter per second
How long does it take sound to travel 1 meter?
The speed of sound is 343.2 meters a second, now you can do the math.
What is the speed of light in units?
The speed of light is 299,792,458 metres per second. That is its speed in SI units. In the antiquated Imperial units, it is approx 186,200 miles per second or 983,570,000 feet per second.
What is the SI unit of speed?
Meter per second (or ) m / smeter per second
What speed does light travel at in a vacuum?
The speed of light in a vacuum is exactly 299,792,458 meters per second. Note that this is exact, because the meter is currently defined on the basis of the speed of light.
Will there be a difference in electricity produced by a normal bicycle and geared bicycle with the dynamo?
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.
How far do you travel in 2 second at 100km?
100 km per what time? speed is not given. Assume speed = 100 km/hour Then in 2 seconds you travel: 100 km/h = 100000/3600 m/second = 1000/36 meter/second in 2 seconds you travel 2000/36 meters = 500/9 meters = 55.6 meters
What is the speed of a meter per second?
There is no speed for a meter per second, because that is a measure of speed itself. A meter per second (m/s) is a measure of speed, just like, say, miles per hour. Calculating speed is putting the distance (m) over time (s) and dividing. In dividing these numbers, you get a unit of speed, in this case, meters per second. A meter per second hasa speed of ONE meter per second.It's sort of like you're asking how many grams a gram weighs.A meter per second is a good walking speed. It is the same as 60 meters per minute, 3600 meters in 60 minutes, or 3.6 kilometers per hour.
How far can you travel in 3 hours on a bicycle at a speed of 6 miles per hour. on a motorboat at a speed of 20 miles per hour?
18 miles on the bicycle, 60 miles on the motorboat.
How fast does sunlight travel from the sun to the earth?
8 min 30 second take time to reach earth.. with speed of 3x10^8 meter sec
How far does light travel in the amount of time it takes sound to travel 1 m?
Speed of sound = 340 meters per second. Time for one meter = 1/340 second Speed of light = 299792458 meters per second Distance in 1/340 second = 299,792,458 / 340 = -- 881.7 kilometers (rounded) -- 547.9 miles (rounded)
What is the S.I unit for speed?
The SI unit for speed is the same as the SI unit for velocity, which is meter per second, or m/s for short.Meter/ sec
