Explaining dark matter and black holes

Here are six big questions about our universe that current physics can’t answer:

What is dark energy, the mysterious energy that appears to be accelerating the expansion of the universe?

What is dark matter, the invisible substance we can only detect by its gravitational effect on stars and galaxies?

What caused inflation, the blindingly fast expansion of the universe immediately after the Big Bang?

For that matter, what caused the Big Bang?

Are there many possible Big Bangs or universes?

Is there a telltale characteristic associated with the death of a universe?

Despite the efforts of some of the world’s brightest brains, the Standard Model of particle physics – our current best theory of how the universe works at a fundamental level – has no solution to these stumpers.

A compelling new theory claims to solve all six in a single sweep. The answer, according to a paper published in European Physical Journal C by Herb Fried from Brown University and Yves Gabellini from INLN-Université de Nice, may be a kind of particle called a tachyon.

Tachyons are hypothetical particles that travel faster than light. According to Einstein’s special theory of relativity – and according to experiment so far – in our ‘real’ world, particles can never travel faster than light. Which is just as well: if they did, our ideas about cause and effect would be thrown out the window, because it would be possible to see an effect manifest before its cause.

Explanation:

Due to travelling faster than light, dark matter has a higher than usual mass in relation to its resting mass, thus accounting for the large 'missing' mass around galaxies. ... Dark matter is therefore non-baryonic, travelling faster than light and has a mass half that of a photon...

Normality of KOH = 0.1062 N

Note: The given question is not clearly stated. A related question below is answered and explained;

What is the NORMALITY of a solution of KOH if 45.18 mL are required to neutralize 0.3g of pure oxalic acid H2C2O4 . 2H2O?

Explanation:

Equation of the reaction: 2KOH + H₂C₂O₄.2H₂O --> K₂C₂O₄ + 4H₂O

molar mass 0f KOH = 56 g/mol; molar mass of H₂C₂O₄.2H₂O = 126 g/mol

Number of moles of in 0.3 g of H₂C₂O₄.2H₂O = mass/molar mass

number of moles = 0.3 g / 126 g/mol = 0.0024 moles

From the equation of reaction, 2 moles of KOH are required to neutralize 1 mole of H₂C₂O₄.2H₂O

Number of moles of KOH required to neutralize 0.0024 moles of H₂C₂O₄.2H₂O = 2 * 0.0024 = 0.0048 moles

Molar concentration of 45.18 mL solution of KOH containing 0.0048 moles of  KOH = number of moles/volume (L)

molarity of KOH solution = (0.0048/45.18 mL) * (1000 mL/1 L) = 0.1062 mol/L

Normality = n * molarity

where is the number of moles of OH⁻ ions produces from  mole of KOH = 1

Normality of KOH = 1 * 0.1062

Normality of KOH = 0.1062 N

Answer: x108(5.03x−42.6)

Explanation: Factor 5.03x109−42.6x108

5.03x109−42.6x108

=x108(5.03x−42.6)

Answer:

See explanation

Explanation:

The equation of the reaction is;

CH3COOCH3 + H2O -------> CH3COOH + CH3OH

Now recall that the rate of reaction refers to the rate of disappearance of reactants or the rate of appearance of products. We indicate that reactants disappear by a negative sign placed in front of the concentration term of reactants.

Rate = k -d[CH3COOCH3]/dt

Rate = k d[CH3COOH]/dt

Rate = k d[CH3OH]/dt

Note; i did not write the rate in terms of water because it is a solvent that is present in large excess. Its concentration does not change with time.

on the left side of the arrow

The reactants in the chemical equation located on the left side of the arrow. Option D is correct.

The arrow in the chemical equation represents the direction of the chemical reaction, and it separates the reactants from the products.

A chemical equation is a symbolic representation of a chemical reaction, showing the starting materials (reactants) and the resulting substances (products). The general form of a chemical equation is as follows:

Reactants → Products

Reactants: The reactants are the substances present at the beginning of the chemical reaction. They are the starting materials that undergo a chemical change or reaction to produce new substances. Reactants were written on the left side of the arrow.

Arrow: The arrow in the chemical equation points from the reactants to the products, indicating the direction of the reaction. It symbolizes the transformation of reactants into products during the chemical reaction.

Products: The products are the substances formed as a result of the chemical reaction. They are the new compounds or elements that are produced by rearranging the atoms of the reactants. Products were written on right side of the arrow.

For example, let's consider the combustion of methane (CH₄) in oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O):

CH₄ (methane) + 2 O₂ (oxygen) → CO₂ (carbon dioxide) + 2 H₂O (water)

In this chemical equation, methane (CH₄) and oxygen (O₂) are the reactants, and they are located on the left side of the arrow. The products, carbon dioxide (CO₂), and water (H₂O), are located on the right side of the arrow.

Hence, D. is the correct option.

Reaction of zinc metal in copper sulfate solution.

[tex]\begin{array}{ll}\text { Oxidation : } & \mathrm{Zn}(s) \rightarrow \mathrm{Zn}^{2+}(a q)+2 e^{-}\\\text {Reduction : } & \mathrm{Cu}^{2+}(a q)+2 e^{-} \rightarrow \mathrm{Cu}(s) \\\hline \text { Full Reaction : } & \mathrm{Zn}(s)+\mathrm{Cu}^{2+}(a q) \rightarrow \mathrm{Zn}^{2+}(a q)+\mathrm{Cu}(s)\end{array}[/tex]

Zinc is listed above copper on the activity series, this means that zinc is more easily oxidized than copper. That is why copper(II) ions can act as an oxidizing agent when put into contact with zinc metal. Ions of any metal that is below zinc, such as lead or silver, would oxidize the zinc in a similar reaction.

Commutator is the answer

Explanation:

The commutator systematically converts the current direction between the rotor and the outer circuit. As the shaft revolves, the commutator converts the course of current in a winding. For a separate armature winding, when a cylinder has reached one-half perfect turn, the winding is now attached so that current passes through it in the reverse of the original direction.

The percent  by volume of a solution : 19.23%

Given

50 ml of ethanol

210  ml of water

Required

The percent  by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

[tex]\tt \%solute(v/v)=\dfrac{solute~volume}{solution~volume}\times 100\%[/tex]

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

[tex]\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml[/tex]

Percent by volume :

[tex]\tt \%volume=\dfrac{50}{260}\times 100\%\\\\\%volume=19.23\%[/tex]

Ionic and covalent bonds can occur in substances that have a repeating lattice structure.

Ionic bonds are formed when an atom donates electron (s) to another atom. Covalent bonds, on the other hand, are formed when two atoms share electrons to complete their octet states.

Ionic compounds are formed from a combination of metal and non-metal atoms. They usually have crystalline lattice structures with high melting points.

Covalent compounds are formed between non-metal atoms. They can also have lattice structures but generally have lower melting points because the forces holding the molecules together are weaker.
