We should see (and have now detected with LIGO) gravitational waves
I believe the correct answer would be kimberlite. Diamonds are usually found in pipes 50 to 200 m across made of kimberlite. It is an igneous rock that is known to contain traces of diamonds. It is named base on the town where it was discovered which is Kimberley, South Africa.
Answer:0.25 times
Explanation:
Given
Distance of satellite from earth surface=Radius of earth
Force on the satellite is F=mg'
where g'=acceleration due to gravity at that point
Distance from center of Earth=R+R=2R
Gravitational Force is given by

Force 
Force on earth surface 
Divide 1 and 2 we get

None of these are a good definition; a good definition would be "the maximum velocity that an object can fall at." however the best answer out go those is c. the constant velocity of some falling objects.
None of the diagrams you attached shows the scenario accurately,
or at all.
Heat flows from Object-B to Object-A, until both objects are at
the same temperature, somewhere between 10°C and 29°C.
