To express the number in the form of a x 10^n, we can convert the given time into scientific notation.
The time taken by light to travel a one-meter distance is less than 0.000000003 seconds. This can be written as 3 x 10^(-9) seconds.
In scientific notation, the number is "3" (a is 3) and the power of 10 is -9 (n is -9). The number "3" is between 1 and 10, and it's one digit smaller than 10.
roughly it takes light less than 0.000000003 of a second to travel a one-meter distance . express the number in the form of
a x 10^n where 1 < a < 10 and is one digit smaller.
