the answer to this question is true
Life cycle assessments are used by various industries to identify and evaluate the total energy impacts of their products and services.
True or False?
Answer:
True.
Explanation:
A product life cycle can be defined as the stages or phases that a particular product passes through, from the period it was introduced into the market to the period when it is eventually removed from the market.
Generally, there are four (4) stages in the product-life cycle;
1. Introduction.
2. Growth.
3. Maturity.
4. Decline.
Life cycle assessment (LCA) also known as life cycle analysis can be defined as an environmental management technique which is typically used by industries to assess, monitor and analyze the impact of the various stages of the life-cycle of their products, systems, processes or activities and services on the environment i.e the cradle to grave impacts.
Generally, life cycle assessments requires a thorough evaluation of the raw materials and energy that are being used in the manufacturing process of a product or service, as well as determining the various emissions into the environment respectively.
For example, in the manufacturing process of a product, life cycle assessment evaluates the impact of the product from raw material extraction (cradle) to production (finished product), distribution, use, and the disposal of the product (grave).
Hence, life cycle assessments are used by various industries to identify and evaluate the total energy impacts of their products and services.
Why is using the proper joining technique important? What could go wrong if the wrong joining technique is used?
Answer:
Explanation:
Using the proper technique is incredibly important because it prevents the materials being joined from breaking and/or causing an accident. If the wrong joining technique is used the materials may not hold in place and come apart easily instead. Also, some joining techniques are not meant for some materials and may instead cause the material to become weak and brittle causing it to break apart almost immediately.
Joining describes a technique which is used to merge two or more independent materials together. The use of wrong joining technique or procedure could result in accident.
In engineering construction, the need to join materials together is always needed for so many reasons. Hence, depending on the materials to be merged, welding, soldering and some other techniques may be employed.
Therefore, wrong or inadequate joining may cause these parts to split or breakup, hence causing severe casualty.

How many horsepower in 337 cc engine
Answer:
11.0 HP
Explanation:
A 100-mm-long strip of metal is stretched in two steps, first to 200 mm and then to 400 mm. Show that the total true strain is the sum of the true strains in each step; in other words, the true strains are additive. Show that, in the case of engineering strains, the strains cannot be added to obtain the total strain.
Answer:
Kindly check the explanation section.
Explanation:
Determine the strain in units in both steps.
For step one, strain = [ final length - Initial length]/ initial length = 200 - 100/ 100 = 1 unit.
For step two, the strain = Â final length - Initial length]/ initial length = 400 - 200/ 200 = 1 unit.
Total strain for the two steps = 1 unit + 1 unit = 2 units.
Estimation using single step is given below;
400 - 100/ 400 = 0.75.
It can be shown from above that the Engineering strength is Addictive.
The next thing to do is to determine the true strength. This is how it can be proved that the strength is Addictive or not.
b1 + b2 = (200 - 100/100) + (400-200/ 200)
b1 + b2 = 1 + 1 = 2.
b(total) = 400 - 100/100 = v2 - v1/v1.
Spray guns atomize liquid true or false?
Answer:
True
Explanation:
Spray gun plays an one of the most important roles in spray finishing as it directs air to atomize the fluid, gives the particles sufficient velocity to reach the product surface, and shapes the pattern/texture. Hope this helps you as much as intended.
Answer: True
Explanation:
The air cap on the spray gun plays an important role in spray finishing as it directs air to atomize the fluid, gives the particles sufficient velocity to reach the product surface, and shapes the pattern.
