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.

How Himalaya s act as a boon for India​
il63 [147K]

Answer:

<em><u>The Himalayas act as a boon for India as they act as a barrier to cold siberian winds. They give tropical touch to the climate of India. They stop rear-bearing monsoon winds from crossing into Tibet and force the wids to shed their moisture within Indian- subcontinent.</u></em>

If you start with a 10g chunk of 235 Uranium how much Uranium will be left after 713 million years?
podryga [215]

Answer:

5g will be left

Explanation:

Uranium 235 have a half-life of 700 million* years. This means that the element will decay to half its initial amount by that time. So if I start with 10g chunk of 235 Uranium, after 713 million years, only half of it (5g) will be remaining.

*the exact half life of Uranium 235 is 703,800,000 years.
