Answer:
- availability of birth control
- migration
- uncertainty about the future
Explanation:
Eastern Europe is a region that has a negative demographic trends. The population is going down, and there isn't a single country of this region that actually has a positive population growth. There are several reasons as to why this is happening. One of the main factors in the migration, as these countries are developing countries and they don't offer high wages and good living conditions, lot of people migrate in Western Europe and North America. Because the economy of these countries is not the best, the people are afraid about their future, so they choose to have one or two children tops, as they are not sure will they be able to afford to have more. The availability of the birth control also had its impact, as the women can be sexually active but not be afraid that they will get pregnant when they don't want to.

Explanation:
Answer: composition in weight percent = 41.25% Cu and 58.75% Zn
Composition in Atom percent = 40.54% Cu and 59.46% Zn
Explanation:
Starting with the composition in weight percent.
Let Mcu= mass of cu and Mzn= mass of zn
%W= weight percent
%Wcu = (Mcu/(Mcu + Mzn)) × 100%
By substituting the values
%Wcu = (33/(33+47)) × 100%
%Wcu = (33/80) × 100%
%Wcu = 41.25%
%Wzn = (Mzn/(Mcu + Mzn)) × 100%
= 47/80 × 100%
%Wzn = 58.75%
Then we can proceed to composition in atom percent
Atomic mass of Cu= Ac = 63.5g/mol
For zn = Az = 65.4g/mol
Atom percent cu = {(%Wcu×Ac)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
Substituting the values
= {2619.375/6461.625}×100%
=40.54% Cu
Atom percent zn = {(%Wzn×Az)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
={3842.25/6461.625}×100%
=59.46% Zn
