Answer:
speed of light = 299,000,000 m/s
Explanation:
The speed of light in vacuum, denoted as c, is a universal physical constant which unlike space and time, is independent of the observer. It is a constant that is important in many fields of science. Its exact value is given as 299,792,458 metres per second.
In scientific notation, it is approximately given as 2.99 x 10⁸ metres per second.
2.99 x 10⁸ metres per second = 2.99 x 100000000 = 299,000,000 m/s
Therefore, when expressed in decimal notation, the speed of light = 299,000,000 m/s.
