A nuetron is the lightest subatomic particle
The plastic rod is made of insulator (plastic), so it does not allow charges moving from one sphere to another. This means that all the electrons given to sphere A will remain on sphere A.
The number of electrons initially given to sphere A is
, and since the charge of 1 electron is
, the net charge left on sphere A after the removal of the rod will be
Answer:
A negatively ionized lithium paste is a conductor.
Explanation:
A conductor is a material that conducts electricity. In other words, a conductor has little resistance to the movement of electric charge or electrons when an electric field is applied.
Insulating materials for electricity are those that offer a certain resistance to the movement of electrons or electric current. In other words, an electrical insulator is a material with a low capacity for conducting electricity.
The best conductors of electric current are metals due to the free electron clouds that favor the circulation of electric current through them.
So, <u><em>a negatively ionized lithium paste is a conductor. </em></u>
The Sun can explode in a supernova. Around the time that sun (massive star) burning finishes, the inert core of Iron in very massive stars will collapse and the star will explode as a supernova.
When the sun explode, their inert iron cores often collapse into an extremely dense neutron star.
In a massive star, hydrogen fusion in the core is accompanied by other different fusion reactions involving heavier elements.
When the core of a massive star dies during a supernova, The supergiant will explodes as a supernova.

c. II and III only (the object has 0 acceleration and the object has constant velocity.)
Why?
Let's discard each of the given options to find the correct one(s).
<h3>
- There are no forces acting on the object:</h3>
False, if an object has a constant speed, it does not mean that there are no forces acting on it, in fact, there will be always acting forces, like frictional force, gravity force, air resistance, and others.
<h3>
- The object has a 0 acceleration:</h3>
True, in an object is moving at constant speed, it means that there is no acceleration, the speed will be the same all the time during motion.
<h3>
- The object has constant velocity:</h3>
True, <u>if an object is moving in a straight line at constant speed</u> the velocity will be also constant. The velocity of an object is referring to its speed and its direction, if the object is moving in a straight line, the direction will be the same, so, if the speed is constant, the velocity will be also constant.
Have a nice day!
