Answer:
Analyzing building related carbon emissions remains as one of the most increasing interests in sustainability research. While majority of carbon footprint studies addressing buildings differ in system boundaries, scopes, GHGs and methodology selected, the increasing number of carbon footprint reporting in response to legal and business demand paved the way for worldwide acceptance and adoption of the Greenhouse Gas Protocol (GHG Protocol) set by the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD). Current research is an important attempt to quantify the carbon footprint of the U.S. residential and commercial buildings in accordance with carbon accounting standards and Scopes set by WRI, in which all possible indirect emissions are also considered. Emissions through the construction, use, and disposal phases were calculated for the benchmark year 2002 by using a comprehensive hybrid economic input–output life cycle analysis. The results indicate that emissions from direct purchases of electricity (Scope 2) with 48% have the highest carbon footprint in the U.S. buildings. Indirect emissions (Scope 3) with 32% are greater than direct emissions (Scope 1) with 20.4%. Commuting is the most influential activity among the Scope 3 emissions with more than 10% of the carbon footprint of the U.S. buildings overall. Construction supply chain is another important contributor to the U.S. building's carbon footprint with 6% share. Use phase emissions are found to be the highest with 91% of the total emissions through all of the life cycle phases of the U.S. buildings.
Explanation:
One of the areas of sustainability research that is receiving the greatest attention right now is the analysis of building-related carbon emissions. Although the bulk of studies on carbon footprints of buildings have different system limits, scopes, GHGs, and methodology choices.
What is construction?Building, road, bridge, or other structure construction, as well as steel structure manufacturing, are all considered to be part of the category of "construction works."
Building for commercial use is referred to as commercial construction. Commercial construction includes building for shops, offices, and educational institutions.
Residential development is concentrated on creating homes. Residential construction includes buildings like houses, apartments, and housing complexes.
With a 6% share, the construction supply chain is a significant contributor to the carbon footprint of American buildings.
With 91% of all emissions from all phases of the life cycle of American structures, use phase emissions are determined to be the greatest.
Thus, this is the scope of residential and commercial construction.

O D. Consult the NEC.
Answer:
D. Measure the voltage on the conductor with a known good meter
Explanation:
In a safe approach to electrical work,the thing that you should always do immediately before touching any electrical conductor is C. Measure the voltage on the conductor with a known good meter.
What should be done immediately before touching any electrical conductor?One should never touch any wires or conductors until you are certain that their electrical supply has been turned off. Circuits must be locked out and marked with a tag to prevent re-energizing them. A conductor is always risky. Before working on a circuit, always test to make sure it is deenergized.
The action you should always do right away before touching any electrical conductor is the safest approach to electrical work. Use a reputable meter to measure the voltage across the conductor.

Question 2
Sarah was recently promoted to a managerial position at her industrial engineering company. With her new role, she is now responsible for overseeing the company's production factory, meaning approximately 50 factory workers now report to her. Although Sarah previously worked as an engineer and did not have any experience running a factory, she is excited to begin her new position. At the end of her first day, Sarah is confused to see her factory workers continuing to work well past the end of their 8-hour shift. She then goes to the factory supervisor (who reports to her) to express concern because the factory does not have the budget to pay so many workers overtime. The supervisor smiles at Sarah and explains that the factory meets production goals by making the factory workers work off the clock. The workers are well aware of this expectation and went along with it in order to keep their jobs. Sarah is shocked to learn this illegal practice had become part of the company culture, but the supervisor explains that the company's CEO (who is Sarah's boss) is well aware of this expectation.
What shouldSarah do ? (15)
Analyzing the information from the case above, the ideal would be Sarah to schedule a meeting with your boss to expose the facts and seek a solution, as this is an ethical dilemma that she became aware of and as a new manager she will have to deal with it.
She became aware of an illegal practice that has become part of the company's culture and that her boss is aware of this illegality.
Sarah needs to be aware that her talk about the possibility of changing company policy and complying with ethics could jeopardize her job.
But on the other hand, if Sarah's boss does not accept to change the company's ethical parameters, she will also be running the risk of being part of this illegal act and damaging her reputation.
Therefore, the best option for Sarah is to be honest and talk to her boss about the situation.
In this way, it can help workers receive their rights, if their argument is accepted, and transform the company into an ethical place with a culture focused on the development and compliance with ethics and legislation.

Why are you asked to draw a sketch of a Bridge-Design on a graph sheet/A4 sheet?
Engineers or architects can be asked to draw a sketch of a bridge-design on a graph sheet or A4 paper to communicate their ideas and scale their drawings.
Architectural sketches are about the communication of ideas. Engineers and architects use hand sketching to clarify elements of the design to the contractor or client.
It should be noted that drawings can also be drawn on a graph sheet or A4 paper to represent the detail before it's eventually constructed.
Scale drawings are used for the illustration of items that are not convenient to draw their actual size. In the construction industry, scales are used depending on the nature of the drawing. Drawings can be made on a graph or A4 paper due to the ease of printing, reproducing, and resizing the drawings.

1- The preexponential and activation energy for the diffusion of iron in cobalt are 1.1×10-5 m 2 /s and 253,300 J/mol, respectively. At what temperature will the diffusion coefficient have a value of 2.1×10-5 m 2 /s ?
The temperature at which the diffusion coefficient have a value of 2.1×10-5 m 2 /s is -47078 K.
Using the relation;
logD = logDo - Ea/2.303RT
D = diffusion coefficient
Do = preexponential
Ea = activation energy
R = gas constant
T = temperature
Substituting values;
log(2.1×10-5)= log (1.1×10-5 ) - 253,300/2.303 × 8.314 × T
log(2.1×10-5) - log (1.1×10-5 ) = - 253,300/2.303 × 8.314 × T
log[2.1×10-5/1.1×10-5] = - 253,300/2.303 × 8.314 × T
0.281 × (2.303 × 8.314 × T) = - 253,300
T = - 253,300/2.303 × 0.281 × 8.314
