The action potential is conducted in only one direction because the brief refractory period inhibits reopening of voltage-gated Sodium (Na) channels.

There is a slight depolarization of the membrane potential which causes the sodium channels residing in the neuronal membrane to open. Therefore, the leading edge of more additional nearby sodium channels gets activated when an action potential is able to depolarize the membrane. This results in another depolarization spike, the leading edge of which opens up more nearby sodium channels, etc.

So, from the point of start, depolarization of waves propagates. The action potential then moves along an axon in every direction. Action potentials, however, go one way. This is due to the sodium channels' ability to close after activation, known as their refractory period. This movement guarantees that the action potential travels along the axon in a particular direction.

The question is incomplete as the mass of copper is also needed to solve this. The given mass of copper is 0.9075 g.

The volume of 6.0 M sodium hydroxide(NaOH) required to fully react with copper nitrate produced is 4.76 ml.

The reaction between copper(Cu) and nitric acid(HNO3) is as follows:

Cu + HNO3 = Cu(NO3)2

According to the above reaction

1 mole of copper produces 1 mole of copper nitrate

Or 63.5 g of copper produces 1 mole of copper nitrate

Thus, 0.9075 g of copper produces 1/63.5 x 0.9075 = 0.0143 moles of copper nitrate

The reaction between sodium hydroxide(NaOH) and copper nitrate {Cu(NO3)2} is as follows:

2NaOH + Cu(NO₃)₂ ---> 2NaNO₃ + Cu(OH)₂

From the above equation,

1 mole of copper nitrate fully reacts with 2 moles of sodium hydroxide

Thus, 0.143 moles of copper nitrate fully reacts with 2 x 0.143 = 0.286 moles of sodium hydroxide

The molarity of the given  NaOH solution is 6 M.

Hence its volume would be

Molarity = No. Of moles/Volume of solution(in liters)

6 = 0.286/ Volume

Volume = 0.0476 liters or 47.6 ml.

Hence, the volume of 6.0 M sodium hydroxide(NaOH) required to fully react with the copper nitrate produced is 4.76 ml.

Answer:

The distance traveled in a certain time will increase

Explanation:

40.1L volume of h2 gas that is measured at 26 c and 100 kpa will be produced from Na of mass given as 3.25g.

Kilopascal (kPa), a 1,000-fold increase in the meter-kilogram-second system’s measure of pressure and tension (the International System of Units [SI]).

Blaise Pascal, a French mathematician and scientist, is honored by its name.

The formula below can be used to translate kg/cm2 into kPa:

A kPa equals 1000 pascals (Pa)

1 kg/cm2 is equal to 98066.5 pascals (Pa), or kPa value multiplied by 1000 Pa.

Thereafter,

T = 26°C

= 299K

P = 100kPa

P= 100/101.325

=0.986923 atm

mass = 3.25g

Atomic mas of H = 1.00784

molar mass of H2 gas = 2x10.00784

= 2.01568g/mol

mole of H2 in 3.25g = 3.25/2.01568 = 1.612359 mol

This gas provided in the question follows the ideal gas equation, so it can be written as

PV = nRT

⇒ V = nRT/P

= (1.612359x 0.0821x 299) / 0.986929

⇒ V = 40.104473

V = 40.1 L

Thus, the volume of gas was found to be 40.1Liter.

Sound from the siren of an emergency vehicle has a frequency of 667.2 hz and moves with a velocity of 349.8 m/s, thus the distance from one condensation to the next is 0.52m.

Waves of sound exist. A disturbance of matter that is conveyed from its source outward is how sound is more precisely defined. Anything that is shifted out of its balance is considered a disturbance.

Some sound waves are classified as periodic waves, which means that the matter’s atoms move in a straightforward harmonic fashion.

As, a string vibrating creates a sound wave. A portion of the string’s energy is used to compress and expand the surrounding air as it oscillates back and forth.

Pressures are a little bit higher and lower as a result. Low pressure regions are rarefactions, and higher-pressure regions are compressions. The air is moved by the pressure anomaly.

(b)  The cube weigh 9.17N before we drill a hole in it.

The Newton's second rule, the definition of density, and the geometric relationships that enable us to calculate the volume of the given figures must all be applied in order to answer this problem.

The volume of a cube with equal sides is found in this situation by

[tex]V_{c} = l^{3}[/tex]

[tex]V_{c} = 5^{3}[/tex] = 125[tex]cm^{3}[/tex]

When it comes to perforated material, we know that its volume is determined by the cylindrical geometry, or

[tex]V_{d} = \pi r^{2} l[/tex]

[tex]V_{d} = \pi (\frac{2.5}{2}) ^{2} *5[/tex] = 12.5[tex]\pi cm^{3}[/tex]

The net volume would be in this case: ΔV = 125[tex]cm^{3}[/tex] - 12.5[tex]\pi cm^{3}[/tex] = 85.75[tex]cm^{3}[/tex] = 85.75×[tex]10^{-6}[/tex][tex]m^{3}[/tex]

Since we already know the weight and gravity, we can use Newton's second law to get the mass,

F = mg

[tex]m =\frac{6.3}{9.8}[/tex]

m = 0.642kg

Part(a) Based on the relationship between density and the mass and volume units, we must use;

ρ = m/v

ρ = [tex]\frac{0.642}{85.75*10^{-6} }[/tex]

ρ = 7486.88kg/[tex]m^{3}[/tex]

So, the density of the metal is 7486.88kg/[tex]m^{3}[/tex]

Part(b) Next, determine the cube's weight.

W = mg = Vρg

W = 125×[tex]10^{-6}[/tex] × 7486.88 × 9.8

W = 9.17N

The index of refraction of a material in which the red-light wavelength is 450 nm is 1.38≤n≤1.67.

Refractive Index (Index of Refraction) is a value calculated from ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by letter n or n' in descriptive text and mathematical equations.

The refractive index  n  is the factor by which wave slows down relative to the speed of light in vacuum  c0 . Almost always, frequency of a wave is constant and so it is the speed and wavelength that change as light passes from one medium into another.

So the wavelength  λ  inside of the medium is related to free space wavelength  λ0  through the refractive index  n .

λ=λ0/n

Red light has free space wavelength  λ0  of anywhere from 620 nm to 750 nm. All of those of wavelengths look red to our eyes. From above equation refractive index is

n1=λ0/λ=620 nm/450 nm=1.38

n2=λ0/λ=750 nm/450 nm=1.67

Based on information you gave, the refractive index could be anything in the range 1.38≤n≤1.67.

The Equilibrium in a game in which players pursue their self-interests and do not cooperate is called as Non-Cooperative Equilibrium.

As opposed to cooperative games, non-cooperative games feature individual player competition, and alliances can only function there if they are self-enforcing. It is conceivable to model cooperation using non-cooperative game theory and competition using cooperative game theory, since the terms "cooperative" and "non-cooperative" are merely technical phrases for the game theory that is used to model a game.

The primary differentiating factor is the lack of an outside authority to set norms mandating cooperative behavior. Players are unable to form coalitions without outside control (such as contract law), therefore they must face off against one another alone.

Hence, Non-Cooperative Equilibrium is the state of a game in which players just look out for themselves and do not collaborate.

What is force?

Force is termed  as the product of mass and acceleration. Terms like stretch and squeeze also can be used to denote force. In Physics, force is defined as: The push or pull on an object with mass causes it to vary its velocity. Force is an external agent capable of adjusting a body's state of rest or motion. it's a magnitude and a direction.

Given information;

A space traveler weighs herself on Earth at a location where the acceleration due to gravity is 9.81 meters per second square.

And force applied on earth 551 N.

The value of mass can be determined by using the formula;

Force = Mass × Acceleration

Mass = [tex]\frac{Force}{Acceleration}[/tex]

Substitute all the values in the formula;

Mass = [tex]\frac{Force }{Acceleration }[/tex]

Mass = [tex]\frac{551}{9.81}[/tex]

Diffusion occurs more quickly in gases than in liquids because the space between the constituent particles in gases is higher than in liquids. Gas particles therefore have more kinetic energy and move more quickly.

Because there is more space between the constituent particles in gases than in liquids, diffusion happens more quickly in gases than in liquids. As a result, the kinetic energy and speed of the particles in gas are increased.
