Answer:
Questions are answered in the explanation section.
Explanation:
a) Of both metals, lead will corrode, since it reacts with seawater to form oxides, chlorides, etc., while bronze is more resistant to oxidation.
b) The corrosion rate will remain constant, because the concentration of seawater does not change over time, therefore, the corrosion rate is independent of the area that is exposed to seawater.
c) Corrosion can be reduced by using protective coatings, so that the metal is isolated from sea water, for example, paints, acrylic powders, etc.
Answer: Collect more information about the extent to which this reported behavior is impacting others
Explanation:
The options are:
a. Collect more information about the extent to which this reported behavior is impacting others.
b. Tell the CEO about what you have uncovered and ask for her permission to speak about it with the CFO.
c. Focus on the CFO’s work performance since his personal behavior is inappropriate in the workplace.
d. Inform the human resources department that there is a potential problem.
Given the information provided in the question, the most effective next step in the process will be to collect more information about the extent to which this reported behavior is impacting others. This will be vital in determining whether what is being said about the Chief Financial Officer is true or not and also to know if true, whether it has an affect on the performance of affected employees in the organization.
Option B is wrong as telling the CEO right away isn't the next step as adequate information must be gathered first.
Option C is also wrong as the focus shouldn't be on his work in the organization alone. His personal behavior should be addressed as well if he's wrong. A great organization is made up of great individuals with good behaviors.
Option D is also wrong as the next step should not be to inform the human resource.
Therefore, the correct option is A.
The number of revolutions the wheel would make will be 37 revolutions. The correct option is B.
<h3>What is circumference?</h3>
The perimeter of the circle is called the circumference of circle.
Given is the wheel diameter CD = Dwheel = 7.45 inches and Length required to cover =144 inches.
For one revolution, distance equal to circumference is moved.
1 rev = π x Dwheel
1 rev = π x 7.45inches
1 rev = 23.393 inches.
No of revolution to travel 540 inches,
= 144/23.393
=6.1557 rev
≈ 6.15 revolutions.
Thus, the correct option is B.

Answer:
0.75 kg
Explanation:
c = Damping coefficient = 3 kg/s
x = Displacement of spring = 0.5 m
F = Force = 1.5 N
From Hooke's law we get
In the case of critical damping we have the relation
Mass that would produce critical damping is 0.75 kg.
Answer: b)All substances emit radiation
Explanation: This is a universal statement that all bodies emit radiations . The radiations are usually in the form of electromagnetic radiations that are being emitted in accordance with temperature that varies from body to body.Even human bodies along with any other body emit radiations These radiations are absorbed by the black body.Therefore the correct option is option(b).
