Answer:

933.33 m/ min

Explanation:

1 mile = 1.6 km

So the car travels 1.6× 35 km in 1 hour

One hour has 60 minutes

So speed of car = 1.6×35 km / 60 minutes

1km = 1000 m

Speed = 1.6×35×1000 m/ 60 minutes

= 933.33 meters per minute

A car is traveling 35 miles per hour. The speed that is measured in meters per minute is 933.33 m/ min.

Speed is the dimension of distance. It is calculated in meters per second. It is the rate of change of an object in a direction. Speed is calculated by dividing the distance by time. It is a scalar quantity.

Given, that a car is traveling 35 miles per hour. The speed is given, in miles we just have to convert the miles into meters per minute. Miles if the English unit of measurement and meter is the SI unit of measurement.

1 mile = 1.6 km

So the car travels 1.6× 35 km in 1 hour

One hour has 60 minutes

So speed of car = 1.6×35 km / 60 minutes

1km = 1000 m

Speed = 1.6 × 35 × 1000 m/ 60 minutes

= 933.33 meters per minute

Thus, the speed of the car is 933.33 m/ min.

Waste is removed from the body in various ways. Kidneys filter out metabolic waste, excess fluid and eliminate it in the form of urine. Lungs exhale CO2 from the deoxygenated blood. The undigested solid waste is egested out from the large intestine. Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs.

Since gas molecules average velocity depends on temperature, oxygen molecules at 25°C are moving faster than oxygen molecules at 0 °C.

According to the kinetic theory of gases, the molecules of a gas are in constant random motion and collide frequently with each other and the walls of the container.

The average speed of gas molecules depends on temperature and molar mass as shown by the relation;

Rutherford proposed the nuclear model of atom. The only one model which can be inferred from this model is nucleus with protons and revolving electrons around.

Rutherford proposed some aspects of atomic structure based on his gold foil experiment. He discovered that the alpha ray is scattering from foil by the repulsion it experienced from the metal.

This results lead to the discovery of positively charged particles in atom latter called as protons. Rutherford proposed that theses protons are located inside the nucleus and the electrons are revolving around the nucleus.

Latter Niels Bohr his student interpreted the nuclear model of Rutherford with quantum mechanics and theory of max planck and he proposed the equations for the determination of energy and momentum of electrons and the radius of atom.

Therefore, no other inferences except the presence of protons and revolving electrons can be obtained from Rutherford's model of atom.

If the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high.

Spectrometry measures the interaction of light with molecules. The absorbance refers to how much light that interacts with molecules of the substance. The more the concentration of the substance the higher the absorbance of the solution.

Hence, if  the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high. An unusually high absorbance tells us that the solution is too concentrated.

Prior to writing the chemical formula of magnesium chloride, a question which any student will need to ask is: A.  What are the oxidation numbers of each atom?

A chemical formula can be defined as a scientific notation that is used to show (represent) the type and total number of atoms that constitute a particular chemical molecule or compound, by using the oxidation number, chemical symbols and subscripts.

Hence, a student would need to know the oxidation numbers of each atom when magnesium chloride is formed after a chemical reaction.

In Chemistry, an oxidation number represents the number of electrons gained or lost by an atom of a chemical element during a chemical reaction.

In conclusion, when magnesium chloride is formed, a question which the student will need to ask prior to writing the chemical formula is "what are the oxidation numbers of each atom?"

The maximum chemical amount in moles of Ni₂ (aq) that can be released into the solution is 0.978 mol.

Using Q = nF where Q = quantity of electricity = 9.439 × 10⁴ C = 94390, n = number of moles of NI₂ (aq) and F = Faraday's constant = 96485 C/mol

Making n subject of the formula, we have

n = Q/F

substituting the values of the variables into the equation, we have

n = Q/F

n = 94390 C/96485C/mol

n = 0.978 mol

So, the maximum chemical amount in moles of Ni₂ (aq) that can be released into the solution is 0.978 mol.

-Sound waves transfer energy by the motion of particles.

Explanation:

These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.

Sound waves transfer energy by the motion of particles considered a type of mechanical energy.

Potential energy plus kinetic energy are combined to form mechanical energy. According to the concept of mechanical energy conservation, mechanical energy remains constant in an isolated system that is solely exposed to conservative forces.

The quantity of energy that a force transfers is known as mechanical work. It is a scalar quantity with joules as its SI unit, much as energy.

Since there are only microscopic forces generated by atomic collisions and no macroscopically quantifiable force, heat conduction is not regarded as a kind of work.

Transverse, longitudinal, and surface waves are the three different forms of mechanical waves. When the wave's energy goes through them, they behave differently in terms of how the medium's particles move.

Thus, option C is correct.

% Composition of elements:

Atomic mass of given elements:

Now, divide % composition by Atomic mass:

[tex]\footnotesize\implies Mg = \dfrac{\% \: Composition}{Atomic \: mass} = \dfrac{75}{24} = \bf 3.125[/tex]

[tex]\footnotesize\implies O = \dfrac{\% \: Composition}{Atomic \: mass} = \dfrac{25}{16} = \bf 1.5625[/tex]

Simplest Ratio:

[tex]\footnotesize\implies Mg = \dfrac{3.125}{1.5625} = 2[/tex]

[tex]\footnotesize\implies O = \dfrac{1.5625}{1.5625} = 1[/tex]

Empirical Formula:

[tex]\footnotesize\implies \underline{ \boxed{ \red{ \bf Empirical \: Formula = Mg_2O}}}[/tex]

The empirical formula will be [tex]Mg_{2}[/tex] .

The simplest entire number fraction of atoms contained in a chemical molecule is its empirical formula.

Calculation of empirical formula:

It is given that, composition of Mg = 75 %, composition of oxygen  = 25%.

It is known that, atomic mass of Mg = 24 g, atomic mass of oxygen = 16g.

By dividing % composition by atomic mass of given elements:

Mg = % composition / %atomic mass

= 75 / 24

= 3.125

Oxygen (O) = % Composition / atomic mass

= 25 / 1.56

Now, calculate simplest ratio of Mg and O.

For Mg = 3.125 / 1.56

= 2.

For O = 1.56 / 1.56

= 1

So, the empirical formula will be [tex]Mg_{2}O[/tex].
