Two asteroids, one with a mass of 6x1012kg, the other with a mass of of 3x109kg, are separated by 70,000m. how large is the force of gravity between them?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
