Answer 1

4)Se da:
[tex]l=10cm=0,1m\\ p=11,3 \frac{g}{ cm^{3} } =11300 \frac{kg}{ m^{3} } \\ m=?kg\\ Formule:\\ m=p*V\\ m=p*l^{3}\\ Calcule:\\ m=11300*0,1^{3}=11,3kg\\ 5)Se-da:\\ m=2kg\\ V=1dm^{3}=0,001m^{3}\\ p=p1=p2=p3=p4\\ V1=0,2dm^{3}=0,0002m^{3}\\ V2=0,4dm^{3}=0,0004m^{3}\\ m3=0,2kg\\ m4=0,6kg\\ m1=?kg\\ m2=?kg\\ V3=?m^{3}\\ V4=?m^{3}\\ Formule:\\ p= \frac{m}{V} \\ m1=V1*p\\ m2=V2*p\\ V3= \frac{m3}{p} \\ V4= \frac{m4}{p} \\ Calcule:\\ Calculezi-deja-p;m1;m2;V3;V4-ca-numi-permite-siteul\\ sa-mai-scriu-caractere.[/tex]
