The libretto of doctor atomic includes excerpts from the Hindu Bhagavad gita, even though Oppenheimer was unfamiliar with that text. The statement is false.

The libretto of Doctor Atomic was created by Peter Sellars, drawing on original source material, including personal memoirs, recorded interviews, technical manuals of nuclear physics, declassified government documents, and the poetry of Muriel Rukeyser, an American poet and contemporary of Oppenheimer.

The storyline of Doctor atomic has it that scientists and soldiers were secretly stationed in Los Alamos, New Mexico, for the duration of World War II as they worked to bring a monstrous weapon to life.

Hence, Doctor Atomic focuses on the days and hours leading up to the first test of the bomb on July 16, 1945.

Further explanation

An electrolyte solution is a substance that produces ions when dissolved in water and can conduct electricity.

Strong electrolytes are the solution

Solutes have the strongest electrical conductivity because they are completely ionized when dissolved in water.

• Weak electrolytes are partially ionized solutions with low electrical conductivity.

• Non-electrolytes are solutions that cannot conduct electricity because the solute cannot form ions. One of the most important properties of water is its ability to dissolve various substances. Solutions in which water is actually the dissolution medium are called aqueous solutions. Water is the most important solvent for electrolytes.

HCl = hydrochloric acid, a strong acid.

HNO3 = nitric acid, strong acid

• NaOH = sodium hydroxide, a strong base

HF = hydrofluoric acid, a weak acid

HC2H3O2 or CH3COOH = acetic acid, a weak acid

C2H5OH = ethanol, non-electrolyte

C6H12O6 = glucose, non-electrolyte

Answer:

I'm not an expert at this, but I assume its mercury.

The highest electric force exerted by charges -4 ×10⁻⁵ C and 3 ×10⁻⁵ C  placed 0.5 m apart is equal to 43.15 N.

The lowest electric force exerted by charges 3 ×10⁻⁵ C and 3 ×10⁻⁵ C  placed 1 m apart is equal to 8.10 N.

According to Coulomb’s law, the force of attraction between two charges is equal to the product of their charges and is inversely proportional to the square of the distance. This electric force applies along the line joining the two charges.

The magnitude of the electric force can be written as follows:

\(\displaystyle F = k\frac{q_1q_2}{r^2}\)

where k is constant proportionality = 8.99 × 10⁹ N.m²/C².

Given the charge on one point charge, q₁ =  4 ×10⁻⁵ C

The charge on the other point charge, q₂ = - 3 × 10⁻⁵C

The distance between these two charges, r = 0.5 m

The magnitude of electric force between the charges  will be:

\(\displaystyle F = 8.99\times 10^{9}\times \frac{4\times 10^{-5}\times 3\times 10^{-5}}{(0.5)^2}\)

F = 43.15 N

Given the charge on one point charge, q₁ =  3 ×10⁻⁵ C

The charge on the other point charge, q₂ = 3 × 10⁻⁵C

Taking into account the Brønsted-Lowry acid-base theory, the conjugate acid of HCO₂⁻ is H₂CO₂.

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions.

Then, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

Like a conjugate acid is an ion or molecule resulting from the base that gains the proton, the conjugate acid of HCO₂⁻ is H₂CO₂.

The molarity of vinegar is 0.47368421 moles per liter.

To calculate this, we can use the following formula:

molarity = (initial_volume - total_volume_change) / final_volume

In this case, the initial volume is 7.5 mL, the total volume change is 21 mL, and the final volume is 28.5 mL. Plugging these values into the formula, we get:

molarity = (7.5 - 21) / 28.5 = -0.47368421

The negative value for molarity indicates that the solution is diluted. This is because the total volume of the solution increased by 21 mL, while the amount of solute (acetic acid) remained the same.

It is important to note that the molarity of a solution can change depending on the temperature. This is because the volume of a solution expands as it gets warmer. Therefore, it is important to measure the volume and temperature of a solution at the same time to get an accurate measurement of its molarity.

The temperature increase from 20 °C to 46 °C indicates that the reaction between zinc and copper sulfate solution is exothermic, with heat being released into the surroundings.

In the given reaction between zinc and copper sulfate solution, the temperature change can provide insights into the type of heat change occurring during the reaction. Based on the provided information, the initial temperature of the copper sulfate solution was 20 °C, and the final temperature of the mixture after the reaction was 46 °C.

The temperature increase observed in this reaction indicates an exothermic heat change. An exothermic reaction releases heat energy into the surroundings, resulting in a temperature rise. In this case, the reaction between zinc and copper sulfate solution is exothermic because the final temperature is higher than the initial temperature.

During the reaction, zinc displaces copper from copper sulfate to form zinc sulfate and copper metal. This displacement reaction is known as a single displacement or redox reaction. Zinc is more reactive than copper and therefore replaces copper in the compound.

The formation of new chemical bonds during the reaction releases energy in the form of heat. This energy is transferred to the surroundings, leading to an increase in temperature. The heat released is greater than the heat absorbed, resulting in a net increase in temperature.

The exothermic nature of this reaction can be explained by the difference in bond energies between the reactants and products. The breaking of bonds in the reactants requires energy input, while the formation of new bonds in the products releases energy.

In this case, the energy released during the formation of zinc sulfate and copper metal is greater than the energy required to break the bonds in copper sulfate and zinc.

5x10⁻⁶ = [HTeH₄O₆⁺]

Explanation:

The first dissociation equilibrium of the telluric acid in water is:

H₂TeH₄O₆ + H₂O ⇄ HTeH₄O₆⁺ + H₃O⁺

Using H-H equation for telluric acid:

pH = pKa + log₁₀ [HTeH₄O₆⁺] / [H₂TeH₄O₆]

pKa of telluric acid is -logKa1

pKa = -log 2.0x10⁻⁸

pKa = 7.699

As concentration of [H₂TeH₄O₆] is 0.25M, replacing in H-H equation:

3.00 = 7.699+ log₁₀ [HTeH₄O₆⁺] / [0.25M]

-4.699 = log₁₀ [HTeH₄O₆⁺] / [0.25M]

Answer:

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.

Explanation:

Answer:

Before Galileo and Newton, many people thought that objects lost speed because they had a built-in natural tendency to do so. But those people weren't taking into account the multiple forces here on Earth - for example, friction, gravity, and air resistance - that cause objects to change their speed. If we could see the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object that is free from any external influence. In deep interstellar space we would observe that if an object had a speed, it would continue to move with that speed until there was some force causing a change in its motion. Likewise, if an object were at rest in interstellar space, it would remain at rest until there was a force causing a change in its motion.

The pH would decrease very little if a small amount of acid is added.

The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.

You need to know the hydronium ion concentration in moles per litre to determine the pH of an aqueous solution (molarity). The equation pH = - log [H3O+] is then used to determine the pH. Example: In a 0.0025 M HCl solution, determine the pH. Strong and entirely ionised in water, HCl is an acid.
