An astronomer has proposed a new theory about the evolution of the universe. what is the next step that the astronomer should take to make his theory reliable? a. allow other scientists to repeat the experiments to verify the results
b. publish the theory in a science magazine to let people know about it
c. discuss the theory on television to make it popular
d. explain the theory with models to make it more interesting

Your correct answer is B. publish the theory in a science magazine to let people know about it.

Explanation:

A) allow other scientists to repeat the experiments to verify the results

Explanation:

Got it right on the test. Plus, by allowing scientists to repeat the experiments help make it become a theory or law. Just because you publish it in some magazine won't make your theory reliable. You need repetition, experimenting, and proof.

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.
