Amanda is giving an informative speech about the human eye and brings a basketball-sized plastic eye to use so that the class can easily see all of the parts that she is talking about. What kind of presentational aid is Amanda using?

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.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

acceleration = 18/3 = 6 m/s per second.

hope i
