Explanation:

In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.

Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.

However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should  find a way to make nylon without using natural resources.

Answer:

D. Electrons are gained and lost

Explanation:

When electrons are gain and lost, redox reaction takes place. In redox reaction, reduction and oxidation tales place simultaneously. Therefore, option D is correct.

Redox reactions include a change in the oxidation state of the substrate. When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.

Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number. The reaction called non-redox if this does not take place.

Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another. Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.

Thus, option D is correct.

Explanation:

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

A spectrum is a  pattern is unique to a substance and can be used identify it.

According to Max Plank, energy occurs in packets called quanta. Hence, energy is not continuous but takes on discrete values which are integer multiples of a fundamental amount.

Again, when a substance is given light energy, a characteristic fingerprint is obtained. This pattern is unique to the substance that has it. These characteristics “fingerprints” are called spectrums.

How are solution optimize ?

To solve an optimization problem, begin by drawing a picture and introducing variables. Find an equation relating the variables. Find a function of one variable to describe the quantity that is to be minimized or maximized. Look for critical points to locate local extrema.

Answer:

I think 1, 4, and 5 are the answers to this question. I am not sure about 4 though.

Explanation:

You have to have a power source (1), you also have to have a way to get that power somewhere else (5), and the reason for 4 would be that the power has to come back through the power source to remain working.

Answer:

100 m/ s²

Explanation:

Newton's Second Law of Motion:

[tex] \boxed{ \mathsf{force = mass \times acceleration}}[/tex]

___________________

In the question:

Note that the quantities here must be in their SI units.

SI unit of Force is Newton(N).

SI unit of mass is kilogram(kg)

Force is already in it's SI unit, while mass isn't.

Converting mass from grams to kilograms:

1000 g = 1 kg

=> 1 g = 1/ 1000 kg

=> 50 g = 50/ 1000 kg

= 1/ 20 kg

___________________

Calculating acceleration:

[tex] \mathsf{5 = \frac{1}{20} \times acceleration }[/tex]

multiplying both sides by 20:

[tex] \implies \mathsf{5 \times 20= (\frac{1}{20} \times 20)\times acceleration }[/tex]

20 on the RHS gets canceled, for it's present on the numerator as well as the denominator.

[tex] \implies \mathsf{100= acceleration }[/tex]

So, here, we got acceleration = 100 m/s².

Since, the other quantities used in the formula are in their SI units, acceleration must be in it's SI unit as well.

The SI unit of acceleration is m/s²
