At 20 c an aluminum ring has an inner diameter of 5.000 cm, and abrass rod has a diameter of 5.050 cm. keeping the brass rodat 20 c, what temperature of the ring will allow the ring to justslip over the brass rod? (αal = 2.4 x 10^-5/c) (αbrass = 1.9 x10^-5/c)
will rate lifesaver.

i think so it’s will be b yes i believe its

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
