A comet is observed to pass $1.50 \times 10^{8} \mathrm{~m}$ from the surface of the Sun. The Sun's radius is $6.96 \times 10^{8}$ $\mathrm{m}$. What is the speed of the comet at this point, if its speed when passing the Earth's orbit, $1.50 \times 10^{11} \mathrm{~m}$ from the Sun's center, is $25 \mathrm{~km} / \mathrm{s}$ ? $\left(\mathrm{M}_{\mathrm{S}}=1.989 \times 10^{30} \mathrm{~kg}\right.$. $)$

The Answer of A comet is observed to pass $1.50 \times 10^{8} \mathrm{~m}$ from the surface of the Sun. The Sun's radius is $6.96 \times 10^{8}$ $\mathrm{m}$. What is the speed of the comet at this point, if its speed when passing the Earth's orbit, $1.50 \times 10^{11} \mathrm{~m}$ from the Sun's center, is $25 \mathrm{~km} / \mathrm{s}$ ? $\left(\mathrm{M}_{\mathrm{S}}=1.989 \times 10^{30} \mathrm{~kg}\right.$. $)$
