Answer: A decrease in acceleration causes the mass to increase.
Explanation:
Let's rewrite this as:
"For a constant force F, we can see that heavier objects accelerate less"
Then, as the mass increases, the acceleration of the object decreases.
This is known as an inverse relationship between acceleration and mass.
By second Newton's law we have that:
F = m*a
Force equals mass times acceleration.
So if the force is constant, we can write it as:
a = F/m.
In this equation, we can see that, if the acceleration decreases and F remains constant, then the mass m must increase (because it is in the denominator)
Then the correct option is:
A decrease in acceleration causes the mass to increase.
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>

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: The speed reading would increase each second by 20m/s
Explanation:
Acceleration is the change in velocity per unit change in time.
Acceleration = velocity/time
∆v = a∆t
Given a = g = 20m/s/s (acceleration due to gravity)
∆t = 1 sec
∆v = 20m/s/s × 1s
∆v = 20m/s
Therefore, the speed reading would increase each second by 20m/s
The wavelength of a wave determines how much it will diffract when it encounters an obstacle
Anything that has mass has weight and anything that has weight has mass simple.
