Problem

Two laboratory measurements are reported as 9.5 N9.5\,\text{N}, 3.275 s3.275\,\text{s} and 0.048 m0.048\,\text{m}. Calculate the quantity Q=9.5 N×3.275 s×0.048 mQ = 9.5\,\text{N} \times 3.275\,\text{s} \times 0.048\,\text{m} and express your answer in scientific notation with the correct number of significant figures. Show all steps of your working, including the final rounding.
