Answer 1

Hi dude

Here is your answer,

Answer 2

Answer:

T₁ : T₂ :: ${10\sqrt{10}}:1$

Explanation:

Due to mutual gravitation,

The time period and distance is related as-

$T^2$ ∝ $a^3$

where,

T = Time period

a = distance from center

Hence,

$T=a^{3\over2}$

In question, for the two planets,

${a_{neptune}\over a_{saturn}} = {10^{13}\over10^{12}}={10\over1}=10$

Hence, their ratio of time periods will be

${T_{neptune}\over T_{saturn}}=({a_{neptune}\over a_{saturn}})^{3\over2}=(10})^{3\over2}\\\\{T_{neptune}\over T_{saturn}}={\sqrt{1000}\over1}\\\\{T_{neptune}\over T_{saturn}}={10\sqrt{10}\over1}$
