What is the speed of light year kilometer per hour?
"Light-year" is not a speed, it is a distance - the distance light travels in a year.The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
What is the scientific notation for the number of kilometers light will travel in 60 seconds?
Speed of light = 17,987,547.48 km per minute:17,987,547.48 km/min in Scientific Notation = 1.798754748 x 107 km/min
What is light speed in km min-1?
Hmm, I don't know what the speed of light is in kilometers per hour but I do know what it is in Kilometers per second which is 300.000 km/sec (3x10^5 - 3 with 5 zeros) Let's see what that translates to if we convert that to km/hr. 300.000 (km/sec) X 3600(seconds in 1 hour) = 1.080.000.000 There you have it. The speed of light is 1.080.000.000 (One-billion-eighty-million) km/hr. If you want to write that down in a scientific manner, you should write 1,08x10^9
Speed of light is around km per second?
299,792.463 km per second.
How fast does light travel from the sun to the moon?
Light takes about 1.28 seconds to travel from the Sun to the Moon. This speed is approximately 299,792 kilometers per second, which is the speed of light in a vacuum.
How long does light to travel 149x10 to the 6 km?
Speed of light = 299,792,458 m/sec .Time = distance/speed = 149 x 109/299,792,458 = 497 seconds
What is the speed of a sailboat that is travelling 100 meters in 120 seconds?
Its speed is exactly 100 meters per 120 seconds. That speed can also be expressed as . . . -- 5/6 meter per second -- 50 meters per minute -- 72 km per day -- 30 km per hour -- 504 km per week . . etc.
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.
How many second to travel 1 km at the speed of 100 km per hr?
0.02777... seconds.
What is the speed of sound and light in KM?
Sound . . . 0.34 km/second Light . . . . 300,000 km/second
Light takes 1.26 s to travel from the moon to Earth in an experiment What is the distance between them at this time?
Light travels at 300,000 km per second, or 186,000 miles per second. Multiply the speed of light in your preferred units times the time to get the distance.
Speed of light from the sun till earth?
The speed of light in a vacuum is about 299,792 kilometers per second. It takes approximately 8 minutes and 20 seconds for light to travel from the Sun to Earth, a distance of about 93 million miles (150 million kilometers).
