6. A 2000 kg spacecraft is located 9.2x10 m from the center of the earth. The mass of the earth is 6.0x1024 kg. What is the force of gravity acting on the spacecraft?

Iwannasay c is the most accurate

Answer///(d) atoms contain small,negatively charged particles;

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
