URGENTE!!

Answer 1

Resposta:

d)

Explicação:

$Coeficiente \ de \ dilatacao \ linear: \alpha\\Coeficiente \ de \ dilatacao \ superficial: 2.\alpha\\Coeficiente \ de \ dilatacao \ volumetrica: 3.\alpha\\\\2.\alpha = 2,4.10^{-5}\\\\\alpha = \frac{2,4.10^{-5}}{2} \\\\\alpha = 1,2.10^{-5}\\\\3\alpha = 3.1,2.10^{-5}\\\\\bold{3\alpha = 3,6.10^{-5}} \ C^{-1}$
