If you "run the clock backwards" using the Friedmann equations, you can avoid a singularity; you just need the pressure and energy to behave in the right way when the Universe was very hot and dense. The catch is that "the right way" in this case means that ρ+3p<0; in other words, either the energy density or the pressure (or both) have to be negative. No conventional forms of matter are known that satisfy this inequality, so unless something really strange was going on in the early Universe, there must have been an initial singularity. (Or, more plausibly, there was a time in the early Universe where the spacetime curvature was sufficiently large that the laws of GR as we know them did not apply.)
Explanation:
Good morning. The answer would be B - the right-front quadrant because rainfall is usually to the right front of the hurricane, which means more rain would fall causing more water to the situation. I hope I helped!! Have a great day.
Answer:
on earth
Explanation:
There are major geological changes such as earthquakes and volcanoes, and there are subtle geological changes, such as those caused by erosion.
- Post-war upheaval, economic turmoil, discontent and entitlement, and Nationalism.
- The Great Depression gave rise to authoritarian governments in Italy, Germany, and Spain.
Answer:
Explanation:
a.Minerals are valuable natural resources being finite and non-renewable. They constitute the vital raw materials for many basic industries and are a major resource for development. ... Since independence, there has been a pronounced growth in the mineral production both in terms of quantity and value.
b.Flowing water picks up soil particles, and carries them along until the flow ebbs and the particles sink to the bottom. ... Anything that reduces the energy of the flow field can cause larger particles to drop below the critical Reynolds number and drop out of the fluid stream (deposition)
c.Afforestation prevents soil erosion because trees grow very large, very strong roots that take hold in soil and prevent it from washing away or being...
