Answer:
No, there are always protons, neutrons, and electrons. When an object is neutral, it means the positive and negative charges sum to zero (are equal and opposite). NO, if an object has no net charge it simply means that the amount of positive and negative charges (protons and neutrons) are the same.
Explanation:
In semiconductors, you can change how easily electrons move through them. That is option 2.
<h3>What are semiconductors?</h3><h3 />
Semiconductors is defined as those substances that possess the characteristics of both metal and non metal.
Examples of semiconductors include the silicon, germanium, and gallium arsenide elements.
The semiconductors are able to conduct electricity through the presence of electrons and holes in them.
The movement of these electrons can be controlled through the addition of impurities to the semiconductor material.
Therefore, in semiconductors, you can change how easily electrons move through them.

Answer:
Option B) The fuel for nuclear fusion comes from sea water
Explanation:
Nuclear fusion can not be carried out by using any type of water as water is composed of stable water molecules (
which is quite difficult to be decayed by any simple method.
Moreover, fusion reactions demands the combination of nuclei of lighter elements for which it makes use of the heavy isotopes of Hydrogen that are Deuterium and Tritium as fuel to carry out the nuclear fusion.
