Answer:
B
Explanation:
Applying law of electrostatic which states that like charges repel each other and unlike charges attract each other
N and S are unlike charges that turn and make the former repulsive force (due to two like charges N and N)to <em>reduce</em> and attractive force between N and S to <em>increa</em><em>se</em>

Explanation:
What does it mean by are represented by is it like cells when things can a cell molecule?
What’s the question ??????????????????? Explain please ?
<u><em>Gamma rays</em></u>
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
(a) The nucleus has most of the mass and comprises most of the volume of an atom; false
The nucleus has most of the mass but the volume of an atom is depends on the distance between the nucleus and the position of the electrons.
(b) Every atom of a given element has the same number of protons; true
They may have different number of neutrons and so you have isotopes but the number of protons remain the same for a given element.
(c) The number of electrons in an atom equals the number of neutrons in the atom; false
The number of electrons in an atom equals the number of protons in the atom.
The electrons are negatively charged which compensate the positively charged protons not the neutrons which do not have a charge (they are neutral).
(d) The protons in the nucleus of the helium atom are held together by a force called the strong nuclear force. true
