L=1km
Y=55*10^6
S=10mm^2
J=217
Oblicz: R,G,U
Wzory:
R=l*s/y
G=1/R
U=J*R
Jednostki bardzo wazne:
w [L] km zamienic na metry
w [S] mm^2 zamienic na metry
I rozwiazac cale. Prosze o pomoc.

R = (1000m x 0,00001 m²) : 55 x 10^6
R = 0,01m³/55 x 1 000 000
R = 0,01/ 55 000 000m³
R = 1/100/ 55 000 000m³
R = 1/5 500 000 000m³ no nieźle ;]
G = 1/ 1/5 500 000 000m³
G = 5 500 000 000m ³
U = 217 x 1/5 500 000 000
u = 217/ 5 500 000 000
