roughly, it takes light lss than 0.000000003 of a second to travel to a one-meter distance. Express this number in the form of ax10^n where 1<a<10 and is a one digit number.
The number is expressed in scientific notation as 3x10^-9, where 3 is between 1 and 10, satisfying the condition.
To express the number in the form of ax10^n, we need to move the decimal point to get a number between 1 and 10.
0.000000003 can be written as 3.0 x 10^(-9).
Therefore, the number can be expressed as 3.0 x 10^(-9), where 1 < a < 10 and a is a one-digit number.
To express the number in the desired form, we need to convert it to scientific notation.
Given that light takes less than 0.000000003 of a second to travel one meter, we can express it as 3 × 10^(-9) seconds.
In scientific notation, we write the number as a decimal between 1 and 10 multiplied by a power of 10. In this case, the decimal is 3, the multiplier is 10, and the power is -9.
Therefore, the number can be written as 3 × 10^(-9) in the desired form.
