2. 279 mm2 = ? km2
3. 666 cm3 = ? um3
4. 900nm/min= ? km/s
5. 676kg/dm3 =? mg/mm3​

Answer 1

Odpowiedź:

Wyjaśnienie:

742 uA = 742:10^7 daA=0,0000642 daA

279 mm^2 = 279 :10^12 km^2=0,000 000 000 279 km^2

3. 666 cm^3 = 666*10^12 um^3=666 000 000 000 000 um^3

4. 900nm/min= 900 *1/10^12 km/60 s=0,000 000 000 015 km/s

5. 676 kg/dm^3 =676* 10^6 mg/ 10*6mm^3​=9 mg/mm^3
