A student used a yardstick to model the displacement of rock at a fault during an earthquake. The student bent the yardstick without breaking it and then let it go. What process did the student show? A. A moment magnitude vibration B. Elastic rebound C. Isostasy D. The formation of a new fault

[ad_1]

Answered by answersmine AT 22/10/2019 – 03:54 AM

I think the correct answer would be B. The process of elastic rebound is being shown by the student. It is a theory that is used to explain earthquakes. It focuses on how energy is being spread in times of earthquakes. As the rocks on the fault experiences shift and force, these rocks would be accumulating energy causing it to deform reaching the internal strength and eventually exceeding it. At that moment, a rapid motion would happen along the fault, which releases the energy, then the rocks would go back to its original shape or the undeformed state. This theory is the first theory that sufficiently was able to explain earthquakes.

[ad_1]

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

The Geologic Time Scale begins at the formation of Earth approximately _____ years ago.

[ad_1]

Answer:

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²    

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

Which of the following statements about the effects of pollution on marine ecosystems is true? a. Burning fossil fuels causes a direct increase in the temperatures of ocean water. b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic. c. Pollution in marine ecosystems causes a decrease in the formation of algal blooms. d. Addition of warm water has no effect on marine ecosystems

[ad_1]

The equation for how temperature changes the resistance R is: 

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. 

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.  

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

Alpha decay is defined as the process in which alpha particle is emitted. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units. The released alpha particle is also known as helium nucleus.

_Z^Atextrm{X}rightarrow _{Z-2}^{A-4}textrm{Y}+_2^4alpha

Option 2: Beta

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.  The released beta particle is also known as electron.

_Z^Atextrm{X}rightarrow _{Z+1}^Atextrm{Y}+_{-1}^0beta

Option 3: Gamma

Gamma decay is defined as the process in which an unstable nuclei gives off excess energy by a spontaneous electromagnetic process and thus releases gamma -radiations. These radiations does not carry any charge and are electrically neutral.

_Z^Atextrm{X}^*rightarrow _Z^Atextrm{X}+_0^0gamma

Option 4: Isotope

Isotope is defined as the chemical specie which belong to the same element but differ in their molecular mass.

Hence, the correct answer is alpha radiation.

The correct answer is – 4) Rainfall.

The rainfall is crucial and the most important factor that contributes to the formation of the soil. The rainfall has such big influence because of few things:

– weathering

The water from the rainfall contributes to the weathering of the rocks, thus making them in little sandy pieces.

– plant life

The plant life needs water to exist, and the rainfall provides that. Further, the plants that die are the biggest factor that helps into the soil formation and fertilization.

– animal life

Once there’s rainfall and plants, the animals can exist too, and the animals are very import in both the fertilization of the soil, and fertilization of the plants that also fertilize the soil.

– decomposition

The dead plants and animals decompose much quicker and much more efficiently when there’s bigger humidity and water, so the rainfall is essential in this process.

What is the average rate of formation of br2?

[ad_1]

Answer:

The motorist average speed for the trip is 88 km/h

Explanation:

In order to know her average speed, we have to refer to the following ecuation:

<V> (average speed) = frac{Vfinal+Vinital}{2}

So, according to that, we know that the motorist has been having a speed of 80km/h during 3 hours, and a speed of 100 km/h during 2 hours. It means that her speed during all the travel is 5 hours.

Then, we have to affect the 5 hours to the inicial and final speed as follows:

First, at 80 km/h, she travels during 2 hours so:

3h*80km/h= 240 km

And then, at 100 km/h:

2h*100km/h= 200 km

Which leads us to:

initial speed: 240 km/ 5 h= 48 km/h

and final speed of: 200 km/ 5 h= 40 km/h

Then, the average speed is:

<V> = 48 km/h + 40 km/h = 88 km/h

There are four types of fundamental forces in nature.These are named as gravitational force,electromagnetic force,strong nuclear force and weak nuclear force.

As per the question we have to understand the role of strong nuclear force and weak nuclear force.

An atom consists of a nucleus surrounded by extra nuclear part consisting of electrons in various orbits.The nucleus contains two basic particles called protons and neutrons .Protons are positively charged while neutrons are neutral.Protons being positively charged will impart repulsive force on each other and may come out of the nucleus.But the nucleus is stable.That is due to the strong nuclear force.

Strong nuclear force is a spin dependent and charge independent force which comes into existence due to the mutual interaction of gluons which binds the protons and neutrons .Hence it is attractive in nature.It’s 100 times more stronger than electromagnetic force also.

Weak nuclear force comes into existence during radio -active decay .This force is due to the exchange of ‘ w’ and ‘z’ bosons[the particles like protons and neutrons having integral or zero spin] which are heavier in nature.The role of it is to change protons into neutrons and vice versa.Its a short range force.

Hence the option D is right.

What does capital formation occur by? (Select all that apply) saving, producing, investing, selling

[ad_1]

Answer:

Americans will pay more for goods produced in Mexico in 2011.

Explanation:

This is a situation of devaluation of the dollar in relation to the Mexican peso. If in 2009 the dollar was worth 16 pesos, but in 2011 it is 14, it means that the purchasing power of the dollar in relation to the Mexican peso has decreased, although it is still high.

In that case, for an American to buy products produced in Mexico in 2011, he or she will spend a little more dollars than he or she would spend in 2009. This is common, since the currencies fluctuate according to the financial market . Thus, the dollar can be valued or devalued, as happened in this example.

If, for example, in 2015 the dollar will buy 20 pesos, it will mean that the dollar appreciated in relation to the peso, increasing the purchasing power of Americans for Mexican products.

Karl Marx developed the economic theory of communism.

Further Explanation:

One of Karl Marx’s most famous contributions came in his book the Communist Manifesto. This book explained Mark’s views on government, the economy, and ultimately lead to the creation of communism as an idea.

A communism system is one that is economic and political in nature. In this system, the government would control the means of production, the distribution of goods and resources, and would overall have significant control over society. This system of communism is the opposite of the capitalist/democratic system used in America today. These two ideologies would clash during the mid 20th century in what is now known as the Cold War.

Marx’s ideas were based on his observations of the world around him. He felt that the mistreatment of labor by industry and private corporations would ultimately lead to an uprising by angry laborers all over the world.

Answer : The mole ratio for aluminium chloride to chlorine is, 2 : 3

Explanation :

The given unbalanced chemical reaction is :

AlCl_3+Br_2rightarrow AlBr_3+Cl_2

First we have to balance the chemical reaction.

In order to balance the chemical reaction, the coefficient 2 is put before AlCl_3text{ and }AlBr_3 and the coefficient 3 is put before Cl_2text{ and }Br_2.

The given balanced chemical reaction will be :

2AlCl_3+3Br_2rightarrow 2AlBr_3+3Cl_2

By the stoichiometry we can say that, 2 moles of AlCl_3 react with 3 moles of Br_2 to give 2 moles of AlBr_3 and 3 moles of Cl_2 as a product.

That means,

The mole ratio between the AlCl_3:Br_2:AlBr_3:Cl_2 are 2:3:2:3 respectively.

Thus, the mole ratio for aluminium chloride to chlorine is, 2 : 3

“Ocean currents result from two processes: the wind on the surface of the water and variation in water temperature and density. These ocean currents are convection currents. Under the tropical sun, water at the equator warms up. At the frigid poles, seawater cools down and sinks. Convection cells are set up with warm water moving along the surface to the poles and deep cold water flowing toward the equator. Changes in the density of ocean waters, caused by changes in salinity re also important in the formation of ocean currents. Ice formation near the poles leaves salt behind in the remaining water. This denser, more saline water sinks, creating its own density-driven currents. Surface winds also set surface currents into motion.” Can you pick the statements that accurately describe oceans currents? Check all the statements that are true. ‘Both the wind and solar energy influence ocean currents.’ ‘Warm water flows away from the equator toward the poles.’ ‘As the salinity of ocean water increases, density decreases.’ ‘Cold water sinks, warm water rises, creating a convection current.’

Answer: The rainfall increases the mineral content of ocean water.

Explanation:

The minerals in the oceanic water are added by the rainfall through surface runoff. It is a phenomena in which the large volume free flowing water flows over the surface of the soil. This water is not absorbed by the soil instead it takes away along with it all surface materials like chemical fertilizers, soil, sediments, inorganic and organic minerals and deposit them to the water body (ocean, river or others).

Thus this can be said that rainfall increases the mineral content of the ocean water.

Graphene Advantages and Disadvantages

Introduction

Graphene is a kind of metal that has a feature of overlapping between the conduction bands and the valence it has. These are arranged in a basic structure of lattice hexagonal that has a single layer of carbon atoms. The different other allotropes of carbon accept it as the basic structure for their formation such as graphite, diamond, charcoal, carbon nanotubes and fullerenes. It is the largest molecule for an aromatic molecule, which is, belongs to the polycyclic aromatic hydrocarbons family. There are many of the properties of the Graphene as in between the ever-tested material it is the strongest that with great efficiency can conduct heat and electricity as it has a nature of being transparent.

It has a structure of levitated by neodymium magnets, which is more than the amount of graphite that has a nonlinear diamagnetism. For many years, scientists have been discovering many of the theories about graphene. For about centuries it is been produced in a very small quantity and used by many of the similar graphite applications like pencils. In 1962, it was first analyzed in electron microscopes but it was studied as a supporting material to metal surfaces. The material used was after some time this material was again designed and studied by Andre Gelm and Konstantin Novoselov In 2004 at University of Manchester. (Anon., 2014)

Advantages and Disadvantages of Graphene

The making of it has concluded many of the theories that describe its existence. Related to making of the two-dimensional material of graphene it was honoured by two Nobel prizes in 2010. It is formed by combining graphite and the suffix -ENE named material that was a single-layered carbon foil. The term Graphene was introduced in 1968 as a single sheet of graphite. It is a six-member carbon ring, which is also known as “infinite alternant” in polycyclic aromatic hydrocarbon. In the previous times, it was stated that these are graphite layers, carbon layers, or may be carbon sheets that may be considered the term, which uses graphite it is not correct to be used as a single layer as it implies three-dimensional structure. (SánchezA. Ureña, 2014)

When we are going to discuss the reactions, structural relations or other properties of individual layers. According to Geim, he said that Graphene is the single atomic plane of graphite that is necessarily extracted from its environment and stands free in that atmosphere as per the need.

Formation

A carbon crystalline allotrope has two-dimensional properties. The carbon atoms of these are packed in a regular hexagonal pattern wire made of atomic scale. Each atom in it has four bonds one is o bond and the other is π bond that has become out of a plane in oriented form. The atoms are in A part from. The lattice in Hexagonal are termed as two interleaving triangular lattices these are used to make the structure of bands calculative for a single graphite layer using a tight binding approximation as well as created a band structure for single graphite using an approximation of tight binding. These can be considered as two interleaving triangular lattices. This myth was its stability is because of its tightly packed atoms of carbon that shows an orbital hybridization, which is a combination of different orbital’s likes, px and py that constitute the O band. (Rfwireless-world.com, 2012)

The bonds together become hybridized that form the π- bands and π∗-bands. The main task of these bands is to handle electronic properties of the notable graphene’s where the free moving electrons made the half bands movement. There are usually many of the evidence has been observed in the Graphene’s sheet. Some single walled nanostructures show the unlayered Graphene rings that have been revealed at the core of presolar graphite onions. The studies show that in flat graphite sheets the defects are being fascinating by these after suggesting a role for the two-dimensional crystallization from a melt.

Advantages and Disadvantages of Graphene

There is a quality of Graphene that it can easily repair its holes when they are going to be exposed in the front of molecules that contains carbon for example hydrocarbons. That is made with pure carbon atoms, Suspended graphene sheets between bars of a grid made of Mattel was studied by TEEM sheets. These are the metals that are being used by the scientists or by the scientific researchers in terms of making too many further metals through it as well as their structures are very much uniquely designed by the overall structure formatting of the new designs in metals as a must. (Quora.com, 2018)

The Flat sheets are rippled in the graphene, which has a diameter of about one nanometer. As two-dimensional crystals are not able to get stable all the time then these ripples are in strict to the material as a result of the isolated real state images by the space satellites. It also makes the formation of these satellites very much sensitively and very much easier as well. In all TEEM images of the graphenes. The atomic resolution of the images of the space is of single layers that are needed to be removed from there in terms of observing TEEM images by observing their rippling that is caused by the graphenes conformation in this regard.

The calculations shows that the size of a graphene is less than about 20 nm that is thermodynamically unstable and it can be made very much stable that depends on the size of it as it is placed only for the more than 24000 atoms large molecules that are needed to make it in a better and efficient way and to utilize it in the most efficient form. The two-dimensional system that is necessary to be shown in the form of similar properties as well as it is related to the working of graphene. These are run under a proper system and that makes the observation of physics very much easy and efficient and to implement it in designing and formatting the actual aspects in this regard.

In such type of systems, the only particles that only be chosen are not always electron, whether they can be optical photons, microwave photons, plasmons, micro activity polaritons or too many other electrons as well. They make a structure like a honeycomb that is able to absorb or release a different nature approach to carbon in order to release them. It can be a photonic crystal that is an array of some of the metallic rods; the nanoparticles made of metal, A lattice of coupled Micro activities are an optical lattice. The following structure building of the Graphenes had made it more different and unique among the masses. (Radianceiitb.org, 2017)

Advantages of Graphenes

  • It is the thinnest material ever discovered until now and as well as it is very much strong enough in its working.
  • The layer it has is only a single one of atoms of carbon that is mostly transparent and pliable in nature.
  • It can easily absorb heat as it is the best conductor of heat and electricity.
  • It is easily be utilized in the making of such electronic devices that can change the technology very much efficiently and with the best speed as these devices are made of very high efficiency by the Graphene,s.
  • They are formed as membranes that very much efficiently separate the gases in between them. These membranes are the sheets and these sheets are made of nanoscale pores that are being created by the Graphene is themselves.
  • They managed the transistors that operate the high-frequency measurements with others. In a comparison of other transistors that are being operated by another slow making of transistors.
  • The displays screens that have been manufactured by using it are of very low cost as well as they are going to make many of the displays of even mobile devices by rearranging the setting of the screens by making it of indium-based electrodes that emit organic lights diodes which also lower power consumptions. This is to be used for the production of batteries that are made of lithium-ions that recharge faster when charged. On the surface of these batteries, Graphenes have been placed.
  • It stores fuel in power cars that stores hydrogen.
  • The water is distilled by using Graphene’s that is nearly equal to the size of nanometer that is used to remove ions from water. (Tetard, 2009)

Disadvantages of Graphene:

There are many methods used to produce the graphene. Through chemical synthesis, the isolated 2D crystal cannot be produced. Maximum electron mobility and fewer defects of graphene are generating by exfoliation, in 2014. With organic as well as inorganic substances are optical method is utilizing to generate instantaneous label-free exchanges of graphene. The chemical potential of graphene is controlled efficiently. When input optical strength is greater than the entrance value, the graphene combination becomes saturated. Beneath strong excitation, graphene can be saturated eagerly.

Ultrafast photonic is the broad property of graphene, this happens because of fiber laser quality of graphene. Graphene oxide layer is tuned electrically this is the result of the optical reaction of it. Due to its wideband optical absorption quality, in graphene, the storable absorption property is used in a microwave. Because of nonlinear Kar effect, graphene has a nonlinear phase shift. In Kar effect graphene is supposed to be a powerful medium, as well as have the ability to observe the non-linear effects, the solution is the most important.

The nonlinear refractive index of graphene is negative, in 2016. Thermal nonlinearity of graphene is determined by thermal lens spectroscopy. Nanostructure graphene can also produce by many methods. Throughout a plating process to generate Ni-graphene merged on an intention substrate, graphene nanosheets can be included in a nickel medium. Graphene is a brittle, in spite of its potency. By using sugar, graphite can be prepared. This is quite safe and atmosphere pleasant method than exfoliation. (ZHANG, 2016)

This technique is used to manage the thickness. We can generate graphene by heating the silicon carbide under low pressure as well as high temperature. In applications, the graphene layer requires being prohibited by the thickness and packing density. With the challenge of production cost, graphene seems to cleave to huge potential.

Here, are some disadvantages of graphene, which described below:

  • Graphene has high cost as well as it is a complex process.
  • Toxic chemicals are used at high temperature to produce graphene. Because of this graphene show signs of some poisonous qualities.
  • The oxidative atmosphere is defenseless against it.
  • Graphene is a good conductor of electricity, graphene doesn’t have a band gap, as well as its mean graphite, can’t be switched off. Researchers are working on this.
  • The material of graphene is very costly on the planet.
  • It is harder to synthesize the non-renewable resource.
  • It is very difficult to generate three-dimensional materials out of graphene, while notable for its narrowness as well as exclusive properties of electrical.
  • Advantages, as well as disadvantages of wonder material, are few along with seeing as the search is not complete yet there is many more things have to come out.
  • The probability of defects is very high due to the larger sheet.
  • Its actual strength is lower than the intrinsic strength.
  • Its’ cannot be stretched quarter of its length.
  • In its atomic structure, there is no defect plus fault but still, it is very difficult to generate a large amount of graphene.(Q. Zheng, 2015)
  • Graphene does not act, as a semiconductor because of this scientist does not use graphene in the microprocessor.
  • The size of graphene sheets produced cannot be controlled.
  • Using graphene solar cell it is very hard to produce sufficient power.
  • If their size is less than 20nm, Graphenes are not stable.
  • The rigidity of the devices is very high bending that is also required to extend as well as squeeze or molded.
  • Graphene is stuck to everything as well as it is a messy stuff.
  • Oxygen along with heat together cannot survive from graphene.
