Answer: 1. recollapsing universe
4. critical universe
3. coasting universe
2. accelerating universe
Explanation:
The universe is continually growing and galaxies are moving apart relative to one another.
These four models foresee the expansion and possible contraction of the universe.
Recollapsing universe: this model predicts that galaxies will stop growing apart and start getting closer to one another. It predicts that there is enough density to stop the growth of the universe in the future.
Critical universe: the universe has the same density as the critical density. This is the difference between the density the universe requires to stop and that of a universe with too little density to ever stop expanding
.
Coasting universe: has enough density to enable galaxies to keep growing apart
, in essence, less than the critical density.
Accelerating universe: this model explains that the distance of far-off galaxies is growing exponentially from an observer over time.
Much of Europe as a whole had many economic goals after World War 2, as this period defined the beginning of the Age of Capitalism. Two of France's main goals were the increase of working hours and productivity gains to rebuild its stability.
The answer would be...
2) the temperature is too cold.
Answer:
A county's birth rate increment is the giving birth or the change in bearingof babies hence a population that is high is achieved.
Explanation:
So the country's population will increase in the reasoning of the number of babies born, and also there might be so many children in population of the country in case, and the youth might be three quarter of the population,while the old might be less or filling the quarter of the population.
