Explain why it was helpful for scientists to compare substrate samples in the arson case discussed in the video. (Forensic Science PBS Video)

Answers

Answer 1

Answer:

Because soil analysis can indicate the existence of flammable substances. Which indicates that the fire was caused by someone in a criminal manner.

Explanation:

As we know, the soil represents the surface layer of the earth where the plants are fixed and remove the nutrients they need to survive.

The soil is formed through the weathering of the rocks having the minerals that its original rock has. The soil has no flammable substance, as it is basically made up of sand, clay and silt. In addition, the soil is a porous environment, which allows any liquid released onto it to infiltrate at a considerable speed.

For this reason in the investigation of a criminal fire, the analysis of soil samples can be very useful. This is because soil analysis can indicate the presence of some flammable substance that has infiltrated. This can confirm that the fire was provoked and was criminal.

Question on edmentum: Type your response in the box.

The video discussed the idea of a self-contained city. Pick a solution mentioned in the video and explain why it will help cities achieve the goal of self-containment.

sample Answer:

A self-contained city can sustain itself and its resources. It does not take more than it needs. Every object can be either reused or recycled productively. One of the people in the video gave the example of compacting and forming trash into different shapes, which can support archways and foundations. This would reduce dependence on the natural resources used for construction, and it would also support recycling.

Give an example of an industry that is likely to locate close to markets. Explain.

Answers

Manufacturers try to locate their factors as close as possible to their inputs and markets to cut transportation cost. Other issues could be the availability of raw material, land, water, labor, power, capital, transport, and market. Examples of these manufacturers and/or industries would be the market for construction workers or “factor markets”. Industries and/or companies such as McDonald’s and other fast food chain, rely on these factor markets for materials to continue to expand and increase the economic growth and success.

which theory supports the fact that a person who goes skydiving for the first time is likey to feel fear before the activity followed by relief after completing the activity
A. the cannon board theory
B. the James Lange theory
C. the facial feedback theory
D. the opponent process theory

Answers

Answer:

D. the opponent process theory

Explanation:

Opponent Process Theory was created by Solomon and refers to moments where an individual has consecutive emotional reactions where the first is the opposite of the second and vice versa.

This theory explains why people who practice skydiving are afraid in the beginning, but a strong satisfaction in the end. This is because, according to this theory, when we are at the beginning of parachuting we feel a sense of fear and fear because of the dangerousness of the activity. However, this feeling is quickly modified at the end of the activity by a feeling of satisfaction, pleasure and happiness because the individual's subconscious understands that he has accomplished something difficult and dangerous.

Final answer:

A person who goes skydiving for the first time experiencing fear initially and then relief aligns with the opponent process theory. This theory stipulates that every emotion triggers an opposing emotion.

Explanation:

The theory that supports the fact that a person who goes skydiving for the first time is likely to feel fear before the activity followed by relief after completing the activity is D. the opponent process theory. This psychological and neurological model proposes that every emotion triggers an opposing emotion. When experiencing a strong emotion such as fear, once the stimulus stops, you feel relief (the opposite emotion).

The initial fear response is referred to as the 'primary process', and the relief afterwards is the 'opponent process'. Over time and repeated experiences, the 'opponent process' i.e., the sense of relief or exhilaration, can strengthen leading to thrill-seeking behaviors.

A book box can hold 24 books. Mrs. Ames had 8 book boxes. If each box is two-thirds full,how many books does mrs.Ames have un the 8 book boxes combined

Answers

Answer:

128 individual books. Mrs Ames could pack about 6 full boxes.

Explanation:

To find a third of 24 divide 24 by 3 you'll find that 1/3 of 24 is 8 so 2/3 of 24 is 16. Multiply 8 by 16 to find how many books Mrs. Ames has total. She has 128 individual books. take 128 and divide that by 24 this should give you the number of boxes Mrs. Ames needs if all the boxes were to be packed full which is 5.333 boxes round up to 6 boxes.
