what could be the possible shape of universe with an evidence.
Answer:
Explanation:
8
When we talk about the "shape" of the universe. It is its intrinsic shape, not the embedding of the universe within a larger space.
It does make sense to talk about the intrinsic shape. Properties like "curvature" can be measured from inside a shape, you don't need suppose that the universe is "in" something to talk about its shape.
Now the space of the universe is three dimensional, this creates visualisation problems. So I'm going to first talk about an imaginary 2d universe:
A 2d universe could be flat, with a curved boundary (like a disc) Or it could be flat with no boundary (an flat infinte plane). Or a 2d universe could be intrinsically curved. If it has positive curvature it could be like the surface of a ball (positive curvature, finite with no boundary) Or shaped like a bowl (positive curvature) Alternatively it could have negative curvature: it could be shaped like a "Pringles crisp" These have negative curvature (this can happen with or without a boundary). Finally there could be regions with different curvature: positive in some parts, negative in others.
The same possibilities exist for our universe: It could be flat (with or without boundary) It could be positively curved (This is intrinsic curvature and your brain can't visualise this for a 3d shape) Or it could be negatively curved (again, don't try to visualise this for a 3d shape, you can't). In the case of positive curvature, it could be finite and unbounded, but for negative curvature, it must either have an edge, or be infinite.
So mathematically these are the possibilities. What does the science say?
We can measure the curvature on large scales. Our measurements are not perfect, there is some room for error. We measure the large scale mass/energy density of the universe, since curvature is caused by gravity, and gravity is caused by mass and energy. If the mass/energy density is > 1 then space would be positively curved. We actually find that the energy density is 1.00±0.02 That is the universe is either flat, or very nearly flat.
No there are profound problems with supposing that the universe has a boundary. But there are also problems with supposing it to be infinite. Scientifically, no edge has ever been detected. So when we build models of the universe, we will generally suppose to have no edge.
Thus our "best guess" is that the universe is uncurved and infinite.

5 Importance of water in human life
Place the following events in chronological order
Answer:
In chronological order means that we must put the events in the order in which they happened.
1. Jawaharlal Nehru is elected prime minister
2. India gains independence

(Q020) Identify the true statement. a. The geothermal gradient is the rate of change in pressure with depth in the Earth. b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface. c. The calculated density at the Earth's center makes scientists almost certain that the inner core is composed of diamond. d. The pressure at the Earth's center is less than 300 times greater than normal atmospheric pressure.
Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.
Explanation:
The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.
This is almost equal to the surface temperature of the sun which is around 5,500° C.

(Q005) Identify the true statement. a. Magma is the term for very hot rock that is molten; when it cools and hardens, it's called lava. b. Igneous rocks form when pre-existing rocks undergo changes in response to heat and pressure. c. Hot, molten rock that cools and hardens produces metamorphic rocks. d. Sedimentary rocks form when pre-existing rock grains are cemented together.
Answer:
d. Sedimentary rocks form when pre-existing rock grains are cemented together.
Explanation:
Sedimentary rocks are formed from the erosion and deposition of preexisting rocks that are accumulated on the surface of the earth. If these rocks like igneous are buried deep they get compacted and form sedimentary rocks.Mention the significance of Northern Plains

What's a representation of something using objects ?
Answer:
physical model. A representation of something using objects.
In the Northern (and Southern) Hemisphere, the ________________ cell is the continuous atmospheric convection cell that has an ascending limb near the equator and a descending limb near 30 degrees latitude. The columns of vertical movement are connected by south-moving winds at low altitudes and north-moving winds at high altitudes.
Answer:
Hadley.
Explanation:
In 1735, George Hadley proposed a model of the atmospheric circulation for planet Earth and it was referred to as the Hadley cell.
Hadley cell are low-latitude overturning circulations which comprises warm, moist air that rises into the atmosphere near the equator and air sinking at roughly 30 degrees latitude.
This ultimately implies that, the Hadley cell is the continuous atmospheric convection cell in the Northern and Southern Hemisphere which have an ascending limb near the equator and a descending limb near 30 degrees latitude.
Additionally, the south-moving winds and north-moving winds connect the columns of vertical movement at low altitudes and high altitudes respectively.

Which is the only state from which water runs in three directions?
Name at least two extinct species that share a close evolutionary relationship with humpback whales.
Answer:
The extinct species called Pakicétus and Indohyus may have had close evolutionary ties to humpback whales. The differences between Indohyus, Pakicetus, and Humpback whales are that Indohyus and Pakicetus both had legs and lived on land, while whales live in the ocean and have no legs. Although the embryo of a humpback whale has limbs that are dormant when it is adult, this could indicate that the animal's ancestors lived on land. Pakicetus and Indohyus are similar to humpback whales because their heads are shaped like long whale skulls. Everything is constantly changing due to evolution, the fossil record of the humpback whale is probably incomplete.

We Nepalese people have diversified climate verification lifestyle and other variation due to cultural variation explain
Answer:
We nepalese people have diversified climate verification lifestyle and other variation due to cultural variation because Nepali itself is divided into 3 regions (terai,hilly and mountain).
People of different culture/ethnicity live in their particular regions such as Sherpas, Manangis,Lopas etc are inhabitant of mountain region. Rai,Limbu,Chettris etc are inhabitant of hilly and Tharus,Brahmin
,Madhesi etc are inhabitant of terai.
Their inhabitants differ their lifestyle as terai people are inhabitant of hot climate,hilly people are inhabitant of mild climate and people on the mountain are inhabitant of cold climate. They celebrate their own culture on the basis of their inhabitants.
