p = F/S⇒F=p×S
F=101325 N/m² × 1 m²⇒ F = 101325 N≈10000 N
a) pisica→3+3=6kg,
G = m×g⇒G = 6 kg × 10 N/kg⇒ G = 60 N, F = G, fals-deci nu e pisica
b) urs→200+200=400kg,
G = m×g⇒G = 400 kg × 10 N/kg⇒ G = 4000 N, F = G, fals-deci nu e urs
c) elefant→5t+5t=10t=10000kg,
G = m×g⇒G = 10000 kg × 10 N/kg⇒ G = 100000 N, F = G, adevarat
-deci e elefant
