At height h above the surface of earth, the gravitational acceleration is what is h? note: the radius of earth is 6380 km.

The acceleration of gravity is inversely proportional to
the square of the distance from Earth's center.

The acceleration of gravity is 9.8 m/s² on the Earth's surface ...
6380 km from the center.

If the acceleration of gravity at 'h' is 4.9 m/s² ... 1/2 of what it is
on the surface, then the distance from the center is

                 (6380 x √2) =  9,023 km  (rounded) ,

and 'h' is the distance above the surface

                     = (9,023 - 6,380) =  2,643 km  (rounded) .

What do you need on

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
