The reaction force in this situation occur once it hits the ground, and normal force from Earth's surface will push up on the ball with 1.4 N.
<em>The correct answer is option (</em><em>C</em><em>) </em>
<h3>
What is Newton's third law of motion?</h3>
Newton's third law of motion states that for every action there is equal and opposite reaction.
Mathematically, this law is given as;
Fa = Fb
where;
- Fa is the force applied by object A
- Fb is the reaction experienced by object B
The force applied by object is equal and opposite the reaction experienced by object B.
When an object placed on the floor, the weight of the object acts downward while the normal reaction of the object acts upwards.
Thus, if you drop a baseball and let it fall, gravity from Earth pulls down on the baseball with 1.4 N of force, the reaction force will occur once it hits the ground, as the normal force from Earth's surface will push up on the ball with 1.4 N.

Answer:They come in different kinds, called elements, but each atom shares certain characteristics in common. All atoms have a dense central core called the atomic nucleus. Forming the nucleus are two kinds of particles: protons, which have a positive electrical charge, and neutrons, which have no charge
Explanation:
The big bang theory refers to a theoretical concept that explains the creation of our universe. It postulates that the universe started with a giant explosion that created all matter and propelled it outwards in all directions. It is the existence of cosmic background radiation that supports the big bang theory within cosmology.
