Professor PC Thomas Classes · Answer

$\mathrm{T}_{	ext {earth }}^{2} \propto \mathrm{R}^{3}$\ $\mathrm{T}_{	ext {jupiter }} \propto(5.2 \mathrm{R})^{3}$\ $\left(\frac{\mathrm{T}_{\mathrm{j}}}{\mathrm{T}_{\mathrm{e}}}ight)=\left(\frac{5.2}{1}ight)^{3}=144 \quad \frac{\mathrm{~T}_{\mathrm{j}}}{\mathrm{T}_{\mathrm{e}}}=12$\
