What are bar graphs similar to? need answers quick pls

Explanation:

A bar graph is very similar to a line graph in the sense that it is designed to show different values of two or more subjects but instead of using lines it using horizontal and vertical bars that represent a different value.

line graphs

Explanation:

line graphs are similar to bar graphs

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.
