how can we overcome the barriers that impede progress toward a more sustainable renewable energy economy?

Answers

Answer 1
Answer:

Answer:

some of the barriers impeding the progress  of attaining a more sustainable renewable energy economy include

  • structural,
  • political and
  • perception hurdles

Explanation:

There must be structure on ground which will facilitate the work on renewable energy provision for the people, also there must be a political will on the part of the Government to accelerate the growth of renewable energy and lastly the perception of the people has to be changed toward accepting the best form of produce power through renewable energy rather than  through fossil fuel

Which is one common use of neutron activation analysis A. Assessing the function of body organs such as the thyroid
B. Killing cancerous cells
C. The transmutation of hydrogen into helium
D. Detecting art forgeries

Answers

Detecting art forgeries  is one common use of neutron activation analysis. Hence, option D is correct.

What is neutron activation analysis?

NAA is a non-destructive analytical technique that can be used to determine the elemental composition of a sample.

It is particularly useful for the analysis of trace elements, as it is highly sensitive and can detect even very small amounts of elements.

In the field of art conservation, NAA is used to analyze the composition of pigments and other materials used in artworks, which can help to authenticate or identify forgeries.

Neutron activation analysis is a highly versatile and powerful analytical technique that can provide valuable insights into the elemental composition of a wide range of samples. Its sensitivity and accuracy make it an important tool in many scientific fields, including art conservation.

Thus, option D is correct.
