Compute the acceleration of gravity for a given distance from the earth's center, dist_center, assigning the result to accel_gravity. 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 for the given program: 9.803495445209855
