When the magnets are released and begin to move, the magnetic force changes potential energy into kinetic energy;<u> option D</u>
<h3>What is magnetic force?</h3>
Magnetic force can be defined as the force of attraction or repulsion that is felt or produced between the magnetic poles and electrically charged moving particles.
Magnetic force is the force that exists due to the attractio or repulsion of objects place around the region of space where a maget exerts its force.
When a magnet is released ai a system of magnets and allowed to move it increases the kinetic eergy of the system by converting potential energy to kinetic energy.

Answer:
C
Explanation:
If the theory were to be proved you you need to repeat the experiment over and over again so that way you can prove that it is true wuth the same results.
Answer: 115m. Displacement can be taken from the distance between the initial point and the final point. In this case,the displacement is 115m.
Answer:
8.2 m/s upward
Explanation:
The motion of the ball is a free fall motion, so we can use the suvat equation:
where:
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
Choosing upward as positive direction:
(acceleration of gravity)
t = 1.5 s
Solving for u, we find the initial velocity:
And the direction is upward.
