How much time you need for 15km with the speed of light?
Since the speed of light is approximately 299,792 kilometers per second, it would take only around 0.00005 seconds to travel a distance of 15 kilometers at that speed.
How fast can light travel in a year?
In a vacuum, light always travels at the same speed, approximately 3 x 10^8 meters/second. In a year, there are 31556736 seconds, so light travels 9.5 x 10^15 meters. That unit is called a light year. More details are available at: http://en.wikipedia.org/wiki/Light-year
An air quality index of 0-15 is?
Very good.
Can nothingness No matter energy etc Travel faster than light If so how fast?
Think about that question. When you say nothing that means that there is nothing to measure the speed of. And nothing can move faster than light, nothing, There is a fixed amount of speed something can have. As speed increases time slows down and at light speed no time passes therefore it is impossible for anything or "nothing" in your questions case can move faster than light. Then again im only 15 so i could wrong but i am answering to the best of my knowladge.
What speed does light travel at in space?
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
Suppose light travels 15 times faster in a vacuum than it does in glass What is the index of refraction for glass Express your answer as a decimal?
The index of refraction is precisely how much faster light travels in a vacuum than in the given medium. In this case, 15. Or perhaps you meant 1.5, which would be more typical for glass - answers.com sometimes eliminates some symbols from the questions.
How far does light travel in a femtosecond?
Femtosecond= 10^-15 secondDistance= Speed x time(10^(-15)) x the speed of light = 2.99792458 × 10-7 m / sOr about 300 nanometers.
A light year is equal to?
Well depends.. If you're saying that the speed of light is 3x10^8 m/s then 1 light year is 9.46728x10^15 metres If the speed of light is exact (299,792,458m/s) then 1 light year would be 9,460,730,472,580,800 metres (9.46073x10^15) Not much difference...

What is the glycemic index of zucchini?
15
What does high reflective index mean?
Reflective Index used to apply to CRT monitors and was a gauge of how much reflected light came off a monitor. A reflective index of < 15% was good. Today's TFT LCD monitors typically have a reflective index of less than 1%, especially those that are backlit, so the term has gone out of use now, and is no longer relevant.
How fast is mach 15?
1150.90 mph 1852.2 km/h or 0.000001716 speed of light not sure how you wanted it

How long would it take to travel 15 km if you could travel at the speed of light?
Light travels 300,000 km per second.It travels 15 km in (15 / 300,000) = 5 x 10-5 = 0.00005 second(0.005 millisecond, 50 microseconds)
If the price index in period 3 is 125 and the price index in period 4 is 140 the rate of inflation between period 3 and 4 is?
Final price index = 140 Initial price index = 125 Therefore, difference in price index between period 3 and 4 is : 140 - 125 = 15 Lastly, 15/125 * 100 = 12%
An air quality index of 0-15 is?
Very good.
