Answer:
16
Explanation:
solution:
by taking the ratio of the energy E_n,be of the nth orbit of a beryllium atom
Z_be=4 to the energy E_n,h of the nth orbit of a hydrogen (Z_h=1) atom gives
E_n,B/E_n,H=-(2.18*10^-18)*Z^2_BE/-(2.18*10^-18)*Zh^2/n^2
=Z^2_BE+/Z^2_H
=(4)^2/(1)^2
= 16
The answer is 2,1,3,2
1. increased production 2. rising demand (occurs twice) 3. increased hiring
hope this helps :)
From britaññica it said time and money. They didn’t have either to switch over from the industrial period and never did. Also from my own person reasoning i think most of the world uses not US customary, so to make stuff more accessible. hope this helps!
