Question

un astronaut are ponderea pe Pamint 900N ce pondere va avea astronautul pe Venus?va rog sa fac rezolvarea

Answer 1

$P_1=900 \ N \\ g_1=10 \ N/kg \\ g_2=9 \ N/kg \\ \boxed{P_2-?} \\ \bold{Rezolvare:} \\ \boxed{P=G=m \cdot g} \\ P_2=m \cdot g_2 \\ m= \frac{P_1}{g_1} = \frac{900 \ N}{10 \ N/kg} \\ m=90 \ kg \\ P_2=90 \ kg \cdot 9 \ N/kg \\ \Rightarrow \boxed{P_2=810 \ N/kg}.$
