Question 19 of 20 5 0 Points A important part of weather science is \"hot air rises\". This is an example of A. conduction B. convection C. radiation es Previous Save F5 FO F F4 F3 F1 F2 Esc Solution \'Hot air rises\' is an example of Convection . It takes place due to bulk motion of molecules within a fluid. Gases and liquid can both be considered fluids. Convection occurs naturally on earth as fluid motion takes places due to differences in density occuring because of change in the temperature gradient. A rise in temperature reduces the density of a fluid and causes it to float over the regions of high density and creates a gap. This gap is filled with surrounding cooler air which rises up again due to heat. This sets up convection current and forms the basis for weather patterns, sea breezes etc Radiation is heat transfer by electromagnetic waves at the speed of light. A hot object radiates heat in the form of waves and it does not require any material medium for propogation. Example for radiation is the Sun\'s energy reaching earth through space which basically is Space (vacuum) having no medium while earth\'s atmosphere consists of air (a composition of gases). .

Title
The Three Methods to Transfer Heat
The above image illustrates the three heat transfer methods. The sun heats the Earth by radiation, the
surface of the Earth heats the air by conduction, and the warm air rises by convection.
What is heat? Heat is energy that moves from a high-temperature object to a low-temperature object. Its unit
is the Joule (J), but sometimes it is measured with the kilocalorie (kcal). The conversion factor between the
two units is 1 kcal = 4186 J. The transfer of heat is processed by the following mechanisms.
Conduction is the process in which heat is transferred through a material. The atoms or molecules in a hotter
part of the material have greater energy than those in a colder part of the material, and thus the energy is
transferred from the hotter place to the colder place. Notice that the bulk motion of the material has nothing to
do with this process. You can easily find examples of conduction. A radiator in your house is one of them. If
you put an object on the radiator, the object will become warmer. Another example is when you pour the
brewed hot coffee into a cold cup; the heat from the hot coffee makes the cup itself hot.
The heat Q conducted during a time t through a bar of length L and cross-sectional area A is expressed as
Q = kA (dT) t / L. Here, k is thermal conductivity, and it depends on the substance; dT is the temperature
difference between the higher temperature and the lower temperature of the bar.
Convection is the process in which heat is transferred by the bulk motion of a fluid. According to the ideal gas
law for constant pressure, the volume (V) is proportional to the temperature (T). V increases as T increases,
and the density decreases within the constant mass. Warm air rises and cooler air goes down; this circulation
makes the energy transported. The generated energy from the center of the sun is transported by convection
near the photosphere. Cool gas sinks while bubbles of hot gas rise. There is a patchwork patte ...

Explain how convection and radiation terms are included in the funda.pdf
Explain how convection and radiation terms are included in the fundamental equation.
Solution
CONVECTION: Flow of heat through currents within a fluid (liquid or gas). Convection is the
displacement of volumes of a substance in a liquid or gaseous phase. When a mass of a fluid is
heated up, for example when it is in contact with a warmer surface, its molecules are carried
away and scattered causing that the mass of that fluid becomes less dense. For this reason, the
warmed mass will be displaced vertically and/or horizontally, while the colder and denser mass
of fluid goes down (the low-kinetic-energy molecules displace the molecules in high-kinetic-
energy states). Through this process, the molecules of the hot fluid transfer heat continuously
toward the volumes of the colder fluid.
For example, when heating up water on a stove, the volume of water at the bottom of the pot will
be warmed up by conduction from the metallic bottom of the pot and its density decreases. Given
that it gets lesser dense, it shifts upwards up to the surface of the volume of water and displaces
the upper -colder and denser- mass of water downwards, to the bottom of the pot.
Formula of Convection:
q = hA (Ts - T ?)
Where h is for convective heat transfer coefficient, A is the area implied in the heat transfer
process, Ts is for the temperature of the system and T ? is a reference temperature.
RADIATION:
It is heat transfer by electromagnetic waves or photons. It does not need a propagating medium.
The energy transferred by radiation moves at the speed of light. The heat radiated by the Sun can
be exchanged between the solar surface and the Earth\'s surface without heating the transitional
space.
For example, if I place an object (such as a coin, a car, or myself) under the direct sunbeams, I
will note in a little while that the object will be heated. The exchange of heat between the Sun
and the object occurs by radiation.
The formula to know the amount of heat transferred by radiation is:
q = e ? A [(?T)^4]
Where q is the heat transferred by radiation, E is the emissivity of the system, ? is the constant of
Stephan-Boltzmann (5.6697 x 10^-8 W/m^2.K^4), A is the area involved in the heat transfer by
radiation, and (?T)^4 is the difference of temperature between two systems to the fourth or
higher power.
Water absorbs the incoming solar Infrared Radiation because the frequency of the internal
vibration of the water molecules is the same frequency of the waves of the solar Infrared
Radiation. This form of Radiative Heat transfer is known as Resonance Absorption.
We humans feel the heat radiated by the Sun and other systems with a higher temperature
because our bodies contain 55-75% of water. The radiative energy inciding on our skin is
absorbed by the molecules of water in our bodies by Resonance Absorption. Just then, the
Infrared Radiation absorbed by our bodies leads to a more intense internal vibration of the water
molecules in our bodies and our bodies get warmer. .

Overview
In this lab, students will carry out several activities aimed at
demonstrating consequences of anthropogenic carbon emissions,
climate change, and sea level rise. To do this, students will model
how certain gases in Earth’s atmosphere trap heat and then how
different colors and textures of surfaces reflect differing amounts
of sunlight back into space. They will create models of sea level
rise resulting from melting of sea ice and glacial ice and examine
the effects of this potential consequence of climate change.
Students will critically examine the model systems they used in
the experiments.
Outcomes
• Explain the causes of increased carbon emissions and their likely
effect on global climate.
• Discuss positive and negative climate feedback.
• Distinguish between glacial ice melt and oceanic ice melt.

Background
For the last 30 years, controversy has
surrounded the ideas of global warming/climate
change. However, the scientific concepts behind
the theory are not new. In the 1820s, Joseph
Fourier was the first to recognize that, given
the earth’s size and distance from the sun,
the planet’s surface temperature should be
considerably cooler than it was. He proposed
several mechanisms to explain why the earth
was warmer than his calculations predicted,
one of which was that the earth’s atmosphere
might act as an insulator. Forty years later,
John Tyndall demonstrated that different
gases have different capacities to absorb
infrared radiation, most notably methane (CH4),
carbon dioxide (CO2), and water vapor (H2O),
all of which are present in the atmosphere. In
1896, Svante Arrhenius developed the first
mathematical model of the effect of increased
CO2 levels on temperature. His model predicted
that a doubling of the amount of CO2 in the
atmosphere would produce a 5–6 °C increase
in temperature globally. Based on the level of
CO2 production in the late 19th century, he
predicted that this change would take place
over thousands of years, if at ...

Unit 5- Discussion - Technology Ethics The textbook- --Technology in A.docx
Unit 5: Discussion - Technology Ethics
The textbook, \"Technology in Action\", states:
\"Because technology moves faster than rules can be formulated to govern it, how technology is used is often left up to the individual and the guidance of his or her personal ethics. Ethical considerations are never clear-cut. They‘re complex and reasonable people can have different, yet equally valid views.\"
What, in your opinion are some examples of how technology is being used unethically? What are some examples of how technology can support ethical behavior? What ethical behaviors do you think are most often ignored by people when using technology?
Course: Intro to Computer (CS140)
***PLEASE CITE ANY AND ALL REFERENCES***
Solution
Technology is never developed according to ethics rather it was developed according to the need and the intention for which it is made off.
technology is developed by a group of person who belongs to some community or may be from different community
Each and every community has a different ehtical value and prosperity so it is quite obvious that technology is being used unethically, becasue as said earlier technology is developed according to the need
Ethical behavior has become even more unclear than before thanks to technology. Having a code of conduct.
Technology is used unethically as human communication over internet allowing people to bully online. Some technology can be use to hack information etc

Two parallel plates are seperated by a distance 2H- The plates are mov.docx
Two parallel plates are seperated by a distance 2H. The plates are moved in opposite directions with constant velocity U0. Each Plate is maintained at uniform temperature T0. Taking into consideration dissipation , determine the heat flux at the plates. Assume Laminar flow and neglect gravity effect.
Solution
lets start the discussion by assuming e1 and e2 as absorptivities and E1 and E2 as emmisive powers of the plates,and also surfaces to be be diffuse and the parallel plates are infinittely long as no information is provided about their lengths.Also consider the space between plates is vaccum.
At surface 1 E1=e1*sigma*T^4
surface 2 E2=e2*sigma*T^4
Now of flux E2 a fraction e1*E2 will be absorbed by surface 1 and rest (1-e1)*E2 will be diffused to surface 2.in the same sense of above e2*(1-e1)*E2 will be reflected on surface towards surface 1.
hence net radiant heat flux leaving surface 2 is=E2 - e2(1-e1)E2 - e2(1-e2)*(1-e1)^2 .........
on summing up geometric series
=E2[e1 / (e1 + e2 -e1*e2)]
similarly
radiant heat flux on surface 2 from surface 1 is
=E1 [e2 / (e1 + e2 - e1*e2)]
The above solving is for constant distance
Now considering our moving plates issue solid angle is given by = Area / D^2 where D is distance between plates whic is D=2H+U(0)*t
But E=integration(i(n)*d(solid angle)) just substituting this expression in above solved method we will get the required solution

Type of financial crisis
Solution
There are mainly 5 types of financial crisis:
1. Banking Crisis - when there is a run on a bank/financial institution. e.g run on Washington Mutual in 2008
2. Currency Crisis - when there is a sudden and wide fluctuation in exchange rate. e.g the recent exchange variation in rouble
3. Speculative Bubbles and Crashes - when there is a sudden crash in the price of speculative assets, like the dot com bubble of 2000
4. International Financial Crisis - Multination crisis, usually caused by very high levels of current account defict. e.g the asian crisis during 1997-98

Typing Answer is Mandatory! Explain the difference between cyclic hydr.docx
Typing Answer is Mandatory!
Explain the difference between cyclic hydrocarbons, aliphatic compounds, and aromatic compounds.
Solution
ALIPHATIC COMPOUNDS
Compounds whose carbon atoms are linked in open chains, either straight or branched, rather than containing a benzene ring. Alkanes, alkenes, and alkynes are aliphatic compounds. For example methane, propane
AROMATIC COMPOUND:
Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single an double bonds. when they follow huckle rule they are called aromatic this  rule states that if a cyclic, planar molecule has 4n+2 ? electrons, it is considered aromatic. For example benzene, toluene
CYCLIC HYDROCARBONS
cyclic compounds are formed when carbon atoms bond together to form ring like structures. All the carbon carbon bonds are single bonds unlike aromatic compounds. For example cyclohexane.

2. To arrive at an accurate balance in Bank reconciliation statement, deposits in transit should be subtracted in book . Example - Book balance after deposit of $ 5,000 - $ 10,000
Bank balance during deposit in transit - $ 5,000. In order to match the balance, $ 10,000 - $ 5,000 = $ 5,000
3.To arrive at an accurate balance in Bank reconciliation statement, the service charged should be subtracted or debited from the cash book. Example - Suppose service charged by the bank is $ 50, already subtracted, in order to meet tha balance, this should be subracted from cash book as well.
4. Double declining method and written down value method ignore salvage value of the asset.
5. Current assets can be defined as the assets which held to be sold within in a period od 12 months. Assets which are held for more than 12 months are non-current assets. Further, current assets are either cash or cash equivalents which can be converted into cash within one year or 12 months.

Two KPMG auditors- Kevin Hall and Rosemary Meyer- were accused of impr.docx
Two KPMG auditors, Kevin Hall and Rosemary Meyer, were accused of improper professional conduct in the audit of the financial statements of USFoodservice, a distribution company. US Foodservice in?ated the revenue reported by the company by recognizing income from ?ctitious promotional allowances or recognizing the promotional allowance early. The two KPMGauditors identi?ed valuation, existence, and completeness of the promotional income and receivable as a signi?cant audit area. During the audit, they found numerous cases where the company recognized promotional income when they should not have. In vouching vendor payments received by the company, the auditor discovered that the company had recognized signi?cant unearned prepayments of promotional allowances as income. The working papers show that the auditors identi?ed the revenue recognition attached to these prepayments as audit adjustments, but the adjustments were subsequently removed by liquid white-out. The very existence of the prepayments in the vendor payment ?le contradicted management
Solution
1)a)The auditor must state in the auditor\'s report whether the financial statements are presented in accordance with generally accepted accounting principle.
b)The auditor must obtain a sufficient understanding of the entity and its environment, including its internal control, to assess the risk of material misstatement of the financial statements whether due to error or fraud, and to design the nature, timing, and extent of further audit procedures.
c) The auditor determines that informative disclosures are not reasonably adequate, the auditor must so state in the auditor\'s report.
In this case, all three points are ignored.
2)No, the auditor not meet the requirements because auditor have improfessional conduct on his report.
3)Auditor failed to do proper Standards of Field Work as well as Standards of Reporting.

Question Five- State the advantages and a major limitation of each of.docx
Question Five: State the advantages and a major limitation of each of the following methods; i) flame atomic absorption spectroscopy (FAAS) ii) electrothermal atomic absorption spectroscopy (EAAS) iii) flame emission spectroscopy (FES) and iv) Atomic fluorescence spectroscopy (AFS) a) (10) b) Explain the advantages of fast Fourier transformation over ensemble averaging enhancement technique. 2)
Solution
a) Advantages of FAAS:
It is inexpensive process,with high precision,and easy to use method.
Disadvantage of FAAS: It is used to analyze only solution of the sample in relatively large amounts,around 1 to 2ml
2)Advantages of EAAS:-No initial addition of chemical reagents required, which minimizes trace metal contamination of the sample.
-Small sample volume is used up,in which entire volume vaporizes
-atom are released in high concentration in small gas volume
-organic molecules breaks up into simpler atoms due to high temperatures before it changes to vapors
-inert gas prevents recombination of atoms
Disadvantage of EAAS:
Imprecision is the major disadvantage of EAAS
Adv of flame emission spectroscopy
-use of inductively coupled plasma gives excellent limit of detection,low chemical interference and multiple element capacity
Disadvantage: several spectral lines and expensive process
Advantage s of AFS
-fluorescence signal has very low background noise so high sensitivity
-resonant excitation offers selective detection of test atom
Disadvantage:poor sensitivity for some elements as they are the ones that absorb visible region wavelengths
B) fast Fourier transformation provides an algorithm converts signal from time domain to frequency domain,that gives much faster computation of discrete Fourier,it being the digitalized version of previous techniques like ensemble averaging
Disadvantage of

Question 19 of 20 5 0 Points A important part of weather science is --.docx
- 1. Question 19 of 20 5 0 Points A important part of weather science is "hot air rises". This is an example of A. conduction B. convection C. radiation es Previous Save F5 FO F F4 F3 F1 F2 Esc Solution 'Hot air rises' is an example of Convection . It takes place due to bulk motion of molecules within a fluid. Gases and liquid can both be considered fluids. Convection occurs naturally on earth as fluid motion takes places due to differences in density occuring because of change in the temperature gradient. A rise in temperature reduces the density of a fluid and causes it to float over the regions of high density and creates a gap. This gap is filled with surrounding cooler air which rises up again due to heat. This sets up convection current and forms the basis for weather patterns, sea breezes etc Radiation is heat transfer by electromagnetic waves at the speed of light. A hot object radiates heat in the form of waves and it does not require any material medium for propogation. Example for radiation is the Sun's energy reaching earth through space which basically is Space (vacuum) having no medium while earth's atmosphere consists of air (a composition of gases).
