Compute the approximate acceleration of gravity for an object above the earth's surface, assigning accel_gravity with the result. The expression for the acceleration of gravity is: (g * m) / (d 2), where g is the gravitational constant 6. 673 x 10-11, m is the mass of the earth 5. 98 x 1024 (in kg), and d is the distance in meters from the earth's center (stored in variable dist_center). Sample output with input: 6. 3782e6 (100 m above the earth's surface at the equator) acceleration of gravity: 9. 81.
