Compute the acceleration of gravity for a given distance from the earth's center, distcenter, assigning the result to accelgravity. the expression for the acceleration of gravity is: (g * m) / (d2), 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 distcenter).sample program: #include int main(void) { const double g = 6.673e-11; const double m = 5.98e24; double accelgravity = 0.0; double distcenter = 0.0; distcenter = 6.38e6; printf("accelgravity: %lf\n", accelgravity); return 0;

B: people should evaluate different forms of savings vehicles based on their needs

When you ask a question you should see a camera at the bottom left, click on it and take your photo!

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
