What is the distant of a light year?
It is the equivalent of how far light can travel at the speed of light in one year.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
What is the speed of sound and the speed of light difference in km per s?
The speed of light in vacuum is 299,792,458 m/s usually rounded to 300,000 km/sec.The speed of sound at sea level is 343 m/s.The difference is 299,792,115 m/s.That's 99.999 886 % of the speed of light, and may also be rounded to 300,000 km/sec.
What is the speed of light and how far does it travel in one Earth year?
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
What is the distant of a light year?
It is the equivalent of how far light can travel at the speed of light in one year.
What is the relationship between light and the speed of light?
Energy is directly proportional to the square of the speed of light (in vacuum), where the constant of proportionality is the mass equivalent of the energy.
What is energy mass?
Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec). The result is in kilograms.Energy has an equivalent mass; you can divide energy (in Joule) by the square of the speed of light (the square of 300,000,000 m/sec).

How long is 9 trillion kilometers away from earth?
That is approximately equivalent to 1 light-year. That is to say, if travelling at the speed of light - the highest possible speed in the Universe - it will take a year to get there.
Is it the speed of light or light speed?
Is what the speed of light or light speed.ANSWER300,000 km/s
What is the speed of sound and the speed of light difference in km per s?

What dos Emc2 mean?
Energy equals mass times the speed of light squared. Energy and mass are equivalent.

Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Which was the fastest the speed of light or the speed of sound?
speed of light
