Semi anthracite has the higest which is 29.5
<u>Answer:</u>
The altitude of planet = 5989.198 km
<u>Explanation:</u>
We know that centripetal acceleration,
, where v is the velocity and r is the radius. In this case both acceleration and velocity is given, so we can find radius of satellite.
v = 
a = 
So, 
We have diameter of earth = 12713 km
Radius of earth = 12713/2 = 6356.5 km
The altitude of planet = Radius of planet - radius of earth
= 12345.698 - 6356.5
= 5989.198 km
