Which of these is an explanation for why it is important for a democratic government to hold regular etections? to preserve the connection between voters and the government to prevent people from losing interest in the political system to keep major political parties in power and dominant over others to strictly limit the amount of time a person can remain politically active

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
