Answer:
Engineering law and ethics are the moral codes associated with the field in which engineers are meant to adhere strictly to.
These ethics help in the safety of the engineers as a result of wearing protective clothing being a part of the ethics . Accuracy should also be taken important in research and daily activities. Corrupt practices and activities which poses risk to the environment is also strictly prohibited.
Answer:
a) Exergy
Explanation:
The useful work potential is called exergy. All practical process are ir-reversible process due to ir-reversibility ,the entropy of system increases and this leads to destroy the energy.
The rate of work is called power.
Reversible work is the maximum obtain work potential because it have all processes reversible.
So from this our option a is right.
Answer:
Migration and indoor planting if too much rain outside.
Explanation:
If rain is a problem, migrating to another place is an option. If you can't leave your place, then I suggest planting inside. (No list was given)
Answer:
Explanation:
It wouldn't work because the wind energy she would be collecting would actually come from the car engine.
The relative wind velocity observed from a moving vehicle is the sum of the actual wind velocity and the velovity of the vehicle.
u' = u + v
While running a car will generate a rather high wind velocity, and increase the power generated by a wind turbine, the turbine would only be able to convert part of the wind energy into electricity while adding a lot of drag. In the end, it would generate less energy that what the drag casuses the car to waste to move the turbine.
Regenerative braking uses an electric generator connected to the wheel axle to recover part of the kinetic energy eliminated when one brakes the vehicle. Normal brakes dissipate this energy as heat, a regenerative brake uses it to recharge a batttery. Note that is is a fraction of the energy that is recovered, not all of it.
A "regenerative accelerator" makes no sense. Braking is taking kinetic energy out of the vehicle, while accelerating is adding kinetic energy to it. Cars accelerate using the power from their engines.
Answer:
C. The Employer
Explanation:
Under OSHA's Confined Space Standard, it is the responsibility of the "employer" to identify or evaluate the spaces whether they are<em> "permit spaces"</em> or<em> "confined spaces."</em> These spaces have<u> serious safety hazards or health hazards.</u> Examples:<em> tanks, vessels, pits, underground vaults, and the like.</em>
The employers need to disclose the information of the permit spaces and their risks to the employees. Thus, he should have a<em> written permit of the permit space</em> if he will be allowing the employees to enter. It is also the employer's responsibility to reduce the hazards imposed to the employees such as<em><u> verifying the entry conditions that are acceptable, making sure the permit space is isolated, providing barriers, etc.</u></em>
