Question

me ajudem por favor​

Answer 1

g = $\frac{G . M}{R^{2} }$

g = $\frac{6,7.10^{-11} . 6.10^{24} }{(6,4.10^{6})^{2} }$

g = $\frac{(6,7 . 6 ).10^{( -11 + 24 )} }{40,96.10^{12} }$

g = $\frac{40,2;10^{13} }{40,96.10^{12} }$

g = $0,98.10^{13 - 12 )}$

g = $0,98.10^{1}$

g ≈ 9,8 $m/s^{2}$

alternativa b)
