If cell g7 contains the function it states that if the value in cell c3 is 9, the number 7 will be assigned to cell g7; if the value in cell c3 is not 9, the number 4 will be assigned to cell g7. =if(g7=7)=then(c3=9)=or(c3=4) =if(c3=9,7,4) =if(g7=9)(g7=7)=or(g7=4) =if(c3=9)(c3=7)=or(c3=4)

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

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.
