Answer:
False.
Explanation:
If you throw a ball into the air, Earth exerts a force on the ball. Also, the ball in the air exerts a force on Earth.
This ultimately implies that, there is a force pair between the earth and the ball.

Answer:The coefficient of friction between the box and the floor, = 1.456 × 10⁻²
Explanation:
Gravitational force is a non-contact force.
Then the magnitude of the net force is the difference between the two forces,
and its direction is the same as the direction of the greater one.
