Question

O MEASUREMENT Multiplication and division of measurements Decide whether each proposed multiplication or division of m proposed multiplication or division Is this possible? result 630. mm yes 0.090 m no 140 ms yes 0.020 s 24. kg ves 4.0 m

Answer 1

Answer:

(1) 630 mm²/0.090 m: Yes the division is possible.

Since 1mm=10^-3 m, then 630 mm²=630 x (10^-3)² m²

630 mm²/0.090 m=630 x (10^-3)² m²/0.090 m=7 x 10^-3 m.

(2) 140 ms²/0.020 s: Yes the division is possible.

Since 1ms=10^-3 s, then 140 ms²=140 x (10^-3)² s²

140 ms²/0.020 s=140 x (10^-3)² m²/0.020 m=7 x 10^-3 s.

(3) 240 Kg/4 m³: Yes the division is possible.

240 Kg/4 m³=60 Kg/m³.

Please let me know if you have any doubt. Thank you.
