P = m v
250 = m5
250 = 5m
m = 50 Kg
Option C
The correct answer is It has equal numbers of neutrons and protons.
A characteristic that can be physically determined, the atomic mass of an atom is equal to the total mass of the protons, neutrons, and electrons that make up the atom. The number of protons in the atom's nucleus is indicated by the atomic number. It is equal to the atomic number in value. Moving over the periodic table causes the nuclear charge to grow. The charge is filled when the electrons approach the protons.
The protons and neutrons of an atom are added to determine the mass number. Therefore, the mass number for each atom will be twice the atomic number (number of protons) if the number of protons (atomic number) and neutrons are identical.

The function of a circuit breaker is to stop a current that is
too great. The speed of the current is not involved.
It would be conductors
Explanation:
conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions.
