Evidence that shows that the observed universe is expanding

The red move saw known to man was one of the primary types of proof for the Enormous detonation. The red move or doppler impact gives proof that the watched items known to mankind are moving far from one another. On the off chance that the items known to man are moving far from one another, the universe is extending.

The rationale is if the universe is growing now it probably been littler at one time. Extrapolating in reverse the universe is proposed to have been at one time a superdense wad of issue.

Such a superdense wad of issue would have been shaky. The Huge explosion recommends that this superdense ball detonated.

The possibility of the universe starting with a touchy extension predicts that there ought to be foundation radiation. This anticipated foundation radiation was found giving additional proof to the Theory of how things came to be.

The Theory of how things came to be was opposed in light of the fact that researchers used to trust that the universe was everlasting and existed in a relentless state. The predominant logical rationality of material authenticity ordered that issue and vitality are on the whole that there is and in this manner must be everlasting. Proof that the development of the universe is expanding in rate demonstrates that the present universe had a start as well as have a consummation.

That's not the way it works.

Real scientists don't gather evidence to support a theory that they made up.

Real scientists build a theory to explain the evidence that they observed.

The so-called "Big Bang" theory is the best explanation ... so far ... of:

-- the observed Cosmic Background radiation,

-- the observed probable expansion of the universe (not "proved"),

-- the observed probable existence of "dark matter" (not "proved"),

-- the observed success of predictions that come from standard theories of fundamental particles, and

-- the observed success of predictions (like GPS) that come from Einstein's general theory of relativity.  

BUT ! If you come up with a better explanation tomorrow ... one that explains the observed evidence more accurately, and makes more accurate predictions of things that we can observe or test ... then the "Big Bang" theory will go out the window, and the scientific world will adopt the "Sid4067" theory for the same evidence that we already have.

What is the longest wavelength of radiation with enough energy to break carbon-carbon bonds?
iogann1982 [59]

The longest wavelength of radiation used to break carbon-carbon bonds is 344 nm.

<u>Explanation:</u>

The longest wavelength of radiation can also be stated as the minimum radiation frequency required to cut carbon-carbon bond should be equal to the threshold energy of the carbon-carbon bonds.

The threshold energy will be equal to the binding energy of the carbon-carbon bonds. As it is known that carbon-carbon bonds exhibit a binding energy of 348 kJ/mole, the threshold energy to break it, is determined as followed.

First, we have to convert the energy from kJ/mol to J, i.e., energy for the carbon-carbon molecules,

\text { Energy } = \frac{348 \mathrm{KJ} / \mathrm{mol}}{6.023 \times 10^{23} \text { photons }} \times 1 \text { mole } \times 1000 = 57.77 \times 10^{-20} = 5.78 \times 10^{-19} J

As,

         E=h v=\frac{h c}{\lambda}

So,

\lambda=\frac{h c}{E}=\frac{6.626 \times 10^{-34} \times 3 * 10^{8}}{5.78 \times 10^{-19}}=3.44 \times 10^{-7}

Thus, \lambda=344 \mathrm{nm} is the longest wavelength of radiation used to break carbon-carbon bonds.

Why do our eyes see the color red when we look at a tomato?
forsale [732]

Answer:

B. Tomatos reflect red light

Explanation:

The only reason colors exist is because the objects with color reflect all other light except for what they are portrayed as. White reflects all colors, and black absorbs all colors.

A flat uniform circular disk (radius = 2.30 m, mass = 1.00 ✕ 102 kg) is initially stationary. The disk is free to rotate in the
Vadim26 [7]

The resulting angular speed = 0.6 rad / s.

<u>Explanation:</u>

Here there is no external torque acting on the system thus we can apply the law of conservation of angular  momentum  

Angular momentum of the man = Iω

Where I = Inertia of the man about the axis of rotation

or         I = M r 2

            I  = 50 * 1.25*1.25 = 78.125

w = Angular velocity of the man, that can be calculated as follows

Tangential velocity of man = v = 2m/s  

So time taken to describe this circle is t = (2*pi* r) / v

Now angle described in 1 revolution θ = 2*pi radians

This angle is subtended in time t = (2*pi* r) / v

Thus angular speed = w = θ/t = 2*pi* ( v/ 2π r) = v/r = 2.70 / 1.25 = 2.16 rad/s

So angular momentum of man = Iw = 78.125 * 2.16 = 168.75.

To conserve the angular momentum before and after,

Angular momentum of disk = angular momentum of the man  

           i.e.             Iw of disk = 168.75

                                disk of I = (disk of M*R^2) / 2

                                              = (1.00 * 102 * 2.30 * 2.30) / 2

                                              = 269.79

                 Thus 269.79 of disk of w = 168.75

      Resulting angular speed of disk = 168.75 / 269.79 = 0.6 ras / s
