When the speed of the particle is close to that of light, it's observed mass would be infinitely large.
To answer the question, we need to know what observed mass is.
What is observed mass in relativity?This is the mass the body of an object in relativistic motion appears to have.
So, observed mass, m' = m/√(1 - β²) where
m = rest mass and β = relative velocity of isotope to light.Now, since the speed of the particle is close to that of light, β ≅ 1.
So, m' = m/√(1 - β²)
m' = m/√(1 - 1²)
m' = m/√(1 - 1)
m' = m/√0
m' = m/0
m' = ∞
So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of "reactions" (total molar mass = 5 grams).
The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.
Why is the energy released in a reaction?Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.
The quantity of energy released in reactions differs according to the reaction type involved.
When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.
The energy, E released in nuclear reactions is given by the formula below:
[tex]E = mc^{2}[/tex]
where m is the mass of the substance and c is the speed of light.
Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.

Apply: For a strong base, the concentration of hydroxide ions [OH–] is roughly estimated to be the same as the concentration of the base. The pH of a strong base is found with the equation pH = 14 + log10[OH–]. Based on their concentrations, find the pH of each of the strong bases. Check your answers with the Gizmo.
Answer
[Ca(OH)2] = ?
pH Ca(OH)2 = ?
[NaOH] = ?
pH NaOH = ?
Litmus is an example of an indicator, a substance that changes color depending on its pH (pH is a measure of the concentration of protons, or H+ ions). In the Titration Gizmo™, you will use indicators to show how acids are neutralized by bases, and vice versa.
To begin, check that 1.00 M NaOH is selected for the Burette, Mystery HBr is selected for the Flask, and Bromthymol blue is selected for the Indicator.
Calculate: Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO3 are dissolved in a liter of water, you would say [HNO3] = 0.6 M.
Because HNO3 is a strong acid, it dissociates almost completely in water. That means the concentration of H+ is very nearly equal to that of HNO3.What is [H+] if [HNO3] is 0.01 M? 0.01 M
The pH of a solution is equal to the negative log of H+ concentration: pH = –log[H+]
Describe: The equation for the reaction of nitric acid (HNO3) and sodium hydroxide (NaOH) is shown on the bottom right of the Gizmo.
Measure: A titration can be used to determine the concentration of an acid or base by measuring the amount of a solution with a known concentration, called the titrant, which reacts completely with a solution of unknown concentration, called the analyte. The point at which this occurs is called the equivalence point.
Explain: A titration curve is a graph of pH vs. volume of titrant. The graph at right shows a typical titration curve for the titration of a strong acid by a strong base. (A strong base is one that has relatively high dissociation in water.)
According to theBrønsted-Lowry definition, an acid is a substance that is capable of donating a proton to another substance. A base is a substance that accepts protons. When an acid and a base are combined, the acid is neutralized as the base accepts the protons produced by the acid.One way to determine if a solution is acidic or basic is to use litmus paper, as shown above. There are two types of litmus papers: red and blue.How does litmus paper indicate an acid? Both strips turn red.

Explanation:
Developing work ethics won't lower your stress although it may make your conscience a little happier. Not B
Not C. Procrastinating just makes things harder. The mountain of things to do is not diminishing at all and your stress knows it.
Not D. Although D is the second best answer, setting goals is not really an action. It is a plan for how to work. But it is not work. Still having a goal is useful.

In a pure sample CH₂F₂, what forces of attraction exists between molecules?
Answer: what is this give more esplanation
Explanation:
The forces of attraction that are present or exist between molecules of [tex]CH_2F_2[/tex] are as follows:
Dipole-dipole interaction.Hydrogen bonding.London Dispersion force. What is the Force of attraction?The force of attraction may be defined as a type of property that pulls the body towards its surface. It is the one through which atoms in molecules or elements are held together with different characteristics on the basis of their structure and functions.
It is known that fluorine has a higher electronegativity than carbon atoms. This difference in electronegativity is responsible for constructing a polar molecule. This significantly illustrates dipole-dipole interaction. It also demonstrates London-dispersion force which refers to the force between atoms and molecules.
It is a mechanism that overall represents the characteristics of each and every element specifically. The force of attraction governs the stability and functionality of the element and molecule as well.
Therefore, The forces of attraction that are present or exist between molecules of [tex]CH_2F_2[/tex] are Dipole-dipole interaction, Hydrogen bonding, and the London Dispersion forces.

A 45.3 g sample of potassium nitrate is dissolved in enough water to make
225 mL of solution. Determine the molar concentration of the potassium nitrate.
Answer:
1.99 M
Explanation:
It gives the mass of a compound, KNO3. First, find the gram formula mass of KNO3. You should get 101.102 g/mol, or something very close. Next, divide given mass by g/mol mass to get number of moles. In this case, 45.3/101.102 = .44806, roughly.
Now, since it says molar concentration, it is asking for moles per liter of solution. If it only gives you 225 mL, or .225 L, you have to adjust for that value. Divide the number of moles you have by number of liters.
.44806/.225 = 1.99 M. This isn't the exact answer, but always remember to round for significant figures. Since both numbers contain 3 significant figures, your answer should have 3. Therefore 1.99 is your answer.
