Jack has been concerned about the rapidly changing green regulations in his state and his ability as a mechanical engineer to ke

ep up with developments in his field relating to green requirements. He wants to talk to his boss about taking a professional sabbatical to increase his knowledge of green mechanical engineering practices. How do you predict Jack will try to convince his boss to agree? (Select all that apply.)
a. Identify how greater knowledge of green mechanical engineering areas, such as robotics or waste management, could extend the company’s service offerings.

b. Explain how a better knowledge of integrated mechanical systems could help the company provide more energy-efficient options to customers.

c. Describe how a smarter selection of more efficient, forward-thinking equipment could help the company’s bottom line.

d. Warn that with regulations and green technology changing so fast, the potential for poor implementation and mistakes is large

Answer:

Option A, B and D

Explanation:

Jack can easily convince boss if he focus around two major aspects of the company

a) Revenue enhancement - Jack must outline the benefits of his research that can be used to improvise customer offerings and  hence can be further used to devise more energy-efficient options to customer

b) Reduction in mistakes - Issues such as poor implementation can be avoided with better approach and understanding.

Hence, option A, B and D are correct

The heavier an atomic nucleus gets, the less energy the star is able to extract from it through nuclear fusion. When it gets to
Slav-nsk [51]

Answer:

Iron

Explanation:

Once a star starts fusing iron in its core it gives off very large amounts of energy. Also helium, hydrogen, carbon, oxygen, and silicon still exist in the star in different shells while fusin is taking place at different parts of the star. Right at the surface, hydrogen continues to fuse to helium, as e go further down helium is fusing to carbon and oxygen; right inside the core we have silicon that is fusing with iron. At this point, Iron being of stable atomic structure and quite heavier will no longer be fused into anything because of the quite large amounts of energy and force required to fuse iron atoms. The process comes to a standstill at this point.

The natural material in a borrow pit has a mass unit weight of 110.0 pcf and a water content of 6%, and the specific gravity of
enot [183]

Answer:

A. 288,030.91 cy

B. The amount of water that must be removed from the natural material is 483541.04254 gallons of water

Explanation:

The natural material in the barrow properties are;

The mass unit weight, γ = 110.0 pcf

The water content, w = 6%

The specific gravity of the soil solids, G_s = 2.63

The desired dry unit weight, \gamma _d = 122 pcf

The water content, w₁ = 5.5 %

The net section volume, V_T = 245,000 cy = 6,615,000 ft³

A.  \gamma _d = W_s/V_T

∴ W_s = V_T × \gamma _d = 6,615,000 ft³ × 122 lb/ft³ = 807030000 lbs

w = (W_w/W_s) ×  100

∴ W_w = (w/100) × W_s = (6/100) × 807030000 lbs = 48421800 lbs

The weight of solids

W = W_s + W_w = 807030000 lbs + 48421800 lbs = 855451800 lbs

V = W/γ = 855451800 lbs/(110.0 lb/ft.³) = 7776834.54545 ft.³ = 288,030.91 cy

V = 288,030.91 cy

The amount of cubic yards of borrow required = 288,030.91 cy

B. The volume of water in the required soil is found as follows;

W_{w1} = (w₁/100) × W_s = (5.5/100) × 807030000 lbs = 44386650 lbs

The amount of water that must be added =  W_{w1} - W_w = 44386650 lbs - 48421800 lbs = -4,035,150 lbs

Therefore, 4,035,150 lbs of water must be removed

The density of water, ρ = 8.345 lbs/gal

Therefore, V = 4,035,150 lbs/(8.345 lbs/gal) = 483541.04254 gal  of water must be removed from the natural material

What issues does society try to forget in order to not have to deal with them ?
velikii [3]

Answer: Homelessness, Drug addiction, Mental Illness, Climate change.

Explanation:

Society would rather be ignorant to/ ignore all of these realities so they do not have to stop specific behaviors or actually acknowledge other people and help. Sometimes people are so stressed out about their own lives, they can not bare another persons issues. People are ignorant to climate change because correcting it requires massive changes and society is selfish and unwilling to change.
