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.?

Answer 1

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.
