Answer:
At the point when non-renewable energy sources are singed, they discharge carbon dioxide and other ozone depleting substances, which thusly trap heat in our air, making them the essential supporters of an Earth-wide temperature boost and environmental change. At the point when we consume oil, coal, and gas, we don't simply meet our vitality needs—we drive the current an unnatural weather change emergency also. Non-renewable energy sources produce huge amounts of carbon dioxide when consumed. Carbon discharges trap heat in the air and lead to environmental change.
A mechanic uses a screw driver to install a ¼-20 UNC bolt into a mechanical brace. What is the mechanical advantage of the system? What is the resistance force if the effort force is 5 lb.
Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs

When checking for a no-start concern, you notice that an engine has no spark. Technician A says to turn on the ignition (engine off) and, using a DMM, find out how much battery voltage is available at the negative terminal of the ignition coil. Technician B says the DMM reading should fluctuate, indicating that the primary coil current is being turned on and off. Who is correct?
A. Neither Technician A nor B
B. Both Technicians A and B
C. Technician B
D. Technician A
Answer:
Option(C) is the correct answer to the given question.
Explanation:
Since overall the On-Board Diagnostics of the level 2 the computer systems need to evaluate the cause of the engine failures .The malfunction significantly increases in the fuel consumption, so that we can detecting the error code in the vehicle.
If we starting the engine as well as by using the DMM, we'll see how much battery voltage it is at the negative ignition coil node.If the spark module is faulty and no ignition coils can fire so all the engines are working that's why all the other option are incorrect .HELP FOR JAVASCRIPT: 01.

It is a cloud-based service. Common examples include but are not limited to
Amazon Web Services (AWS)Google Compute Engine (GCEDigitalOcean Microsoft AzureAs highlighted above, they offer small business the advantage of high-quality IT infrastructure at very affordable costs. Businesses that want to shed the cost of their IT infrastructure whilst increasing their computing powers are most likely to purchase these services. E.g. start-ups or companies reviewing/implementing a cost restructuring.
Of course, one of the disadvantages of (IaaS) is that companies have to forfeit complete control of their physical infrastructure. Furthermore, because it is online, computing speeds may be dampened by internet speed.

The syntax of an UPDATE SQL command is:
UPDATE table_name SET column = value, where condition
From the question, the table name is COMPANY.
So, we have:
UPDATE COMPANY SET column = value, where condition
The update statement is to increment the COMM column by 500.
So, the query becomes
UPDATE COMPANY SET COMM=COMM + 500 WHERE condition
Lastly, only columns where SALES are greater than 20000 should be updated.
So, the complete command is:
UPDATE COMPANY SET COMM=COMM + 500 WHERE SALES> 20000;

you've finished programming the app! Now your company has to decide whether to use an open source
license or proprietary license. explain which one you would choose and why.
Answer:
Proprietary License gives you full ownership and trademark/patent opportunites. Open source allows for code donation and a community based development for your app. Generally speaking, if your a private entity creating an app for a client, you'll need the Proprietary Licence, which will allow you to sell the codebase to your client.
If your creating an app for your company as itself, you go either way, sell the license in licensing agreements, or have your companies community contribute and better your app from the inside.
Its entirely based on the agreements you set for the app.
Why are proper ergonomics important for learning? Students can socialize more when their work area is comfortable. Students can study better if their work area is comfortable. Students are able to take longer breaks when their work area is functional. Students experience more physical strain if their work area is functional.
Answer:
The correct answer to the following question will be Option B (Students can research easier if their environment is convenient).
Explanation:
Ergonomics defined as the study including its type of job individuals do, the world in which they job as well as the resources people utilize to perform the function.School operation, because this is not a working circumstance, is always at the discretion of "cause and effect," such that, there might not be a standard that satisfies the food safety performance indicators of learning spaces, while adequate ergonomics seems to be very necessary since students will learn easier if their working environment was indeed pleasant.The other three choices are not related to the given scenario.

2-It is important that measurements be consistent in engineering because
A-There is only one established system of measurement available
B-there is one unit that is used to measure weight, length and distance
C-engineers often work together internationally and replicate each others' results
Answer:
The answer to this question can be described as follows:
In question 1, the answer is False.
In question 2, Option C is correct.
Explanation:
Recycling seems to be the concept of organizing life by making use of as little resources as possible. The recycling approach enables us to live and reconstruct in modules that are closed, it use everywhere not only in the open system. Measurements must be accurate in engineering because engineers often operate independently globally and repeat the findings of one another.
