Answer:
B) Electrons and protons
Explanation:
Each proton has a positive charge, and each electron has a negative charge. If the atom is electrically neutral, there must be the same number of electrons and protons.
A) and C) are wrong. Neutrons have no charge, so they can't counteract that of the protons or the electrons.
D) is wrong. The atomic number is the number of protons, and the mass number is the number of protons plus neutrons. The neutrons can't counteract the charge of the protons,
In an electrically neutral atom of any element, the number of electrons equals the number of protons. This balance gives the atom its neutrality. Atomic number and atomic mass do not directly relate to the atom's electrical state.
In an electrically neutral atom of any element, there are equal numbers of electrons and protons. This balance between the negatively charged electrons and positively charged protons ensures the overall electrical neutrality of the atom. Neutrons, which are neutral particles, do not affect electrical neutrality. The atomic number represents the number of protons in an atom while the atomic mass, close to the number of neutrons, is the sum of protons and neutrons.

Answer:
See the explanation below
Explanation:
Due to the frictional force, this force acts in the opposite direction to the movement of the person's shoe. This force tends to wear the sole of any shoe. We must remember that the frictional force is defined as the product of the normal force by the coefficient of friction between surfaces.
For this case, it should be the coefficient of dynamic friction between the pavement and the material of the sole of the shoe
