Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning).
Change in speed = (132 m/s) - (zero m/s) = 132 m/s
Acceleration = (132 m/s) / (3.94 s)
Acceleration = (132/3.94) m/s²
<em>Acceleration = 33.5 m/s² </em>(about 3.4 G's)
According to the research, the correct option is b. The main difference between both is that kinetic energy involves motion, and potential energy involves position.
<h3>What are kinetic energy and potential energy?</h3>
Kinetic energy refers to that energy that a body or system possesses due to its movement and like any other type of energy, it can be converted into heat and other forms of energy.
On the other hand, potential energy is the energy that is capable of generating work as a result of the position of the body and is classified according to the forces that give rise to it, such as gravitational, elastic, chemical, among others.
Therefore, we can conclude that according to the research, the correct option is b. The main difference between both is that kinetic energy involves motion, and potential energy involves position.

Answer:
330 m/s approx
Explanation:
The RMS speed of a gas is proportional to square root of its absolute temperature is
V ( RMS ) ∝ √T
Here V₁ = 200 , T₁ = 23 +273 = 300K , T₂ = 227 +273 = 500 K
Putting the values
200 / V₂ =
V₂ = 330 m/s approx
Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
It's 0 m/s because you're both moving on the same machine at the same speed, so it appears that they're not moving
