Answer: plz mark as brainliest and follow me please

Explanation:•Kepler's Third LAW:

The cube of the MEAN distance of a planet from the sun is directly proportional to the square of time TAKEN to move around the sun.

where , r is the mean distance from the sun

¶¶¶ SOLUTION:

Given,

height of satellite =  m

time taken by satellite for one revolution around earth = T sec

When satellite takes  seconds for one revolution, height of satellite = ?

Cross Multiply

8(R+h_{1})^{3} = (R+h_{2})^{3}

\implies 2^{3}(R+h_{1})^{3} = (R+h_{2})^{3}

\implies (2(R+h_{1}))^{3} = (R+h_{2})^{3}

\implies (2R+2h_{1})^{3} = (R+h_{2})^{3}

APPLYING cuberoot on both sides, we get

\implies 2R+2h_{1} = R+h_{2}

\implies h_{2} = 2R+2h_{1}-R

\implies h_{2} = R+ 2h_{1}

•°• If satellite takes 2\sqrt{2}T seconds for one revolution, then height of satellite = R+2h_{1}
