ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. Divide 0.0081 meters by 300 seconds and express the answer in scientific notation.?

To divide 0.0081 meters by 300 seconds, we first perform the calculation: ( \frac{0.0081}{300} = 2.7 \times 10^{-5} ) meters per second. The number 0.0081 has two significant figures, and 300 has one significant figure (when treated as a whole number without a decimal). Thus, the final answer should be expressed with one significant figure: ( 3 \times 10^{-5} ) m/s.
