Question

Evaluate (724 mm)/(37 s) to three significant figures and express answer in $l units using an appropriate prefix. Express your answer to three significant figures and include the appropriate units. (724 mm)/(37 s) = Evaluate (27 ms times 0.064 Mm)/(340 mg) to three significant figures. Express your answer using three significant figures. (27 ms) (0.046 Mm)/(348 mg) = Mm middot s/kg Evaluate (2.68 mm) (426 Mg) to three significant figures. Express your answer using three significant figures. (2.68 mm) (426 Mg) = km middot kg

Explanation / Answer

a) 724 mm / 37s = 724 * 10-3 m / 37 s

= 0.020 m / s

b) 27 ms * 0.046 Mm / 348 mg = 27 * 10-3 s * 0.046 Mm / 348*10-6 Kg

= 3.569 Mm . s / Kg

c) 2.68 Mm * 426 Mg = 2.68 * 10-6 Km * 426 * 10-6 Kg

= 1141.68 * 10-12 Km . Kg
