are you sure
Yes, I am sure. The spheres A - C are attracted to D because D is closest to all three bodies. Gravity is a force that depends on the distance between objects, so the closer the objects are to each other, the stronger the gravitational attraction between them.
okay thank you
You're welcome! If you have any more questions, feel free to ask.
Tyson and Grayson decide to have a tug of war contest. Grayson pulls the rope with all his might and so does Tyson. Sadly, Tyson only pulls with half the force that Grayson pulls with. Which way will the rope move?

Newton's 3rd Law. For every action there is an equal and opposite reaction. James's action is not enough to move as fast as Heidi.

Newton's 2nd Law. James is pulling the heavier load. He needs a greater force to move as fast as Heidi.
