What evidence supported the Oscillating Big Bang?

stira [4]

<h2>Answer with Explanation </h2>

The Oscillating Universe Theory is a cosmological model that consolidates both the Big Bang and the Big Crunch as a major aspect of a repeating occasion. That is, in the event that this hypothesis remains constant, the Universe in which we live in exists between a Big Bang and a Big Crunch.

As such, our universe can be the first of a conceivable arrangement of universes or it tends to be the nth universe in the arrangement.

As we probably are aware, in the Big Bang Theory, the Universe is accepted to extend from a hot, exceptionally thick, and little element. Actually, on the off chance that we extrapolate back to the snapshot of the Big Bang, we can achieve a point of peculiarity described by unendingly high vitality and thickness, just as zero volume.

This portrayal would just mean a certain something every one of the laws of material science will be tossed out of the window. This is naturally unsuitable to physicists. To exacerbate the situation, a few cosmologists even trust that the Universe will, in the end, achieve the greatest purpose of development and that once this occurs, it will at that point crumple into itself.

This will basically prompt indistinguishable conditions from when we extrapolate back to the snapshot of the Big Bang. To cure this difficulty, a few researchers are suggesting that maybe the Universe won't achieve the purpose of peculiarity all things considered.

Why do people have symptoms in their bodys

weeeeeb [17]

Body works like a computer whenever there is any problem it warns you and those warnings are termed as symptoms. Of the body doesn't show symptoms we won't be able to detect the problem in our body.

Semi-trailer trucks have an odometer on one hub of a trailer wheel. The hub is weighted so that it does not rotate, but it conta

shtirl [24]

Answer:

1020 km

Explanation:

A complete rotation of the wheel equals a distance of 1 circumference.

The circumference is

$C = \pi d$

where d is the diameter of the wheel.

300,000 rotations = $300000\pi d = 300000\times\pi\times1.08\text{ m} = 1017876.0\ldots\text{ m}$

In kilometers, this is = 1017876/1000 km = 1020 km

A hayride wagon is going down a spooky country road at 15 m/s when a Scarecrow appears in the roadway. The man at the wheel of t

nexus9112 [7]

Answer:

d = 68.18 m

Explanation:

Given that,

Initial velocity, u = 15 m/s

Finally it comes to stop, v = 0

Acceleration, a = -1.65 m/s²

Time, t = 2.5 s

We need to find the distance covered by the hayride before coming to a stop. Let d is the distance covered. Using third equation of motion to find it :

$v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{-(15)^2}{2\times -1.65}\\\\d=68.18\ m$

So, the hayride will cover a distance of 68.18 m.

At an altitude of 5000 m the rocket's acceleration has increased to 6.9 m/s2 . What mass of fuel has it burned?

sergey [27]

1) Initial upward acceleration: $6.0 m/s^2$

2) Mass of burned fuel: $0.10\cdot 10^4 kg$

Explanation:

There are two forces acting on the rocket at the beginning:

- The force of gravity, of magnitude $F_g = mg$ , in the downward direction, where

$m=1.9\cdot 10^4 kg$ is the rocket's mass

$g=9.8 m/s^2$ is the acceleration of gravity

- The thrust of the motor, T, in the upward direction, of magnitude

$T=3.0\cdot 10^5 N$

According to Newton's second law of motion, the net force on the rocket must be equal to the product between its mass and its acceleration, so we can write:

$T-mg=ma$ (1)
