Question

przelicz :

1. 36 km/h na m/s i cm/min

2. 10m/s2 na cm/min2 i km/h2

3. 2m3 na cm3

4. 1000cm3 na m3

Answer 1

a) 36km/h=36·1000m/3600s=10m/s

36km/h=36·100000cm/60min=60000cm/min

 

b)10m/s²=10·100cm/(1/60min)²=1000cm/(1/3600min²)=3600000cm/min²

10m/s²=10·0,001km/(1/3600h)²=0,01km/(1/12960000h²)=129600km/h²

 

c) 2m³=2·1m·1m·1m=2·100cm·100cm·100cm=2·1000000cm³=2000000cm³

 

d) 1000cm²=1000·1cm·1cm·1cm=1000·0,01m·0,01m·0,01m=1000·0,000001m³=0,001m³
