A hammer (mass 0.850 kg) rests on the surface of a table. What is the magnitude and the direction of the force of the table pushing on the hammer? If the force acts upward, enter a positive value and if the force acts downward, enter a negative value. What is the magnitude and direction of the force of the hammer pushing on the table? If the force acts upward, enter a positive value and if the force acts downward, enter a negative value. What is the magnitude and direction of the force of the hammer pulling on Earth? If the force acts upward, enter a positive value and if the force acts downward, enter a negative value. Which forces must be equal in magnitude and opposite in direction even though they are not interaction partners?

(1) The force of Earth pulling on the hammer.

(2) The force of the table pushing on the hammer.

(3) The force of the hammer pushing on the table.

(4) The force of the hammer pulling on Earth.
