Answer:

The type of succession is:

Primary succession

Explanation:

This is a type of succession that occurs after a volcanic eruption or earthquake; it involves the breakdown of rocks by lichens to create new, nutrient rich soils.

Primary succession is one of the two types of succession we have. It begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil.

Explain why advances in technology can actually create more problems for engineers.

andrew11 [14]

Explanation:

Engineering is science in practical terms. It is the application of scientific findings in problem solving and creating a better world.

How does technological advancements create more problems for engineers?

Loss of job to automation: the world is driving at automating work processes through the use of specially designed and crafted machinery. Work is now properly being done using machines with little to no human input in the whole process. This is a huge let off for engineers. Engineers have to compete with machines which are their own inventions for jobs now.
Fast paced work environment: machines can handle work more efficiently and faster than the people making them. There is an increasing race between engineers and their own inventions today for better product delivery. Unless a machine is faulty, they are more productive and efficient than man. This can cause engineers to want to catch up with their own inventions leading to a work life of stress.
Environmental problems they cannot solve: most inventions use components from the environment. They release effluents that are very difficult to be properly disposed or stored. This is a huge problem for engineers and can lead to ethical calls from the government and the populace. In short, they can create problems they are expected to solve but cannot solve.
Social problems: engineers can be portrayed as terrible beings for their own inventions. This leads to psychological problems on a good and creative invention. For example, rare earth metals in DR Congo are instrumental in making solar panels, but mining of these metals have forced several thousands of people into hard and intense labor on mines; there is a call on technological firms to stop exploiting people this way for their own gains.
Misuse of technology: any good technology can be put into the wrong use. A nuclear reaction can be packaged into a bomb and also, it can be the center of electricity generation on a commercial scale. How can engineers solve this kind of problem? Technological inventions are subjective in their usage.

Respiratory protection ____________________________ against fumes and gases.

anygoal [31]

Respiratory protection <u>provides fool proof protection</u> against fumes and gases during wielding.

PPE is an acronym for personal protective equipment and it can be defined as a terminology that is used to denote any piece of equipment which is designed and developed to offer protection to different parts of the body while working in a potentially hazardous environment.

Some examples of personal protective equipment (PPE) that are used to protect the different parts of the body include the following:

Respirators
Face mask
Face shield
Gloves
Boots
Helmet

In conclusion, respiratory protection <u>provides fool proof protection</u> against fumes and gases during wielding.

Which of the following distinguishes a reservoir from an accumulator?

lozanna [386]

Answer:

Reservoirs usually have zero pressure

Explanation:

accumulators are controlled by pressure valves while reservoirs are not

accumulators "accumulate" pressure while reservoirs are used to store "overflow" fluids for later use if needed

Estimate the theoretical fracture strength of a brittle material if it is known that fracture occurs by the propagation of an el

Alex17521 [72]

Answer:

theoretical fracture strength is 9916.58 MPa

Explanation:

given data

surface crack of length L = 0.26 mm

radius of curvature r = 0.004 mm

stress So = 1230 MPa

solution

we get here theoretical fracture strength S that is express as

S = $S_{0} \times \sqrt{\frac{L}{r} }$ .................1

here So is stress and L is length and r is radius

put here value and we get

S = $1230 \times \sqrt{\frac{0.26}{0.004} }$

solve it we get

S = 9916.58 MPa

so theoretical fracture strength is 9916.58 MPa

It is acceptable to miss used absorbentes

Flauer [41]

Explanation:

I assume you meant mix instead of miss because the question wouldn't make sense otherwise.

I'd have to guess and say it is acceptable, because in order to comply with the used oil rule, a facility must properly manage its oil-contaminated sorbents (i.e., don't mix other wastes with these sorbents), and it must either recycle sorbents or send them for disposal at a permitted facility that burns them for energy recovery.

If this is incorrect, don't hesitate to report this answer.
