Factors of Production.

Answer:

Resources needed to provide goods or services are called factors of production

Explanation:

Further Explanation:

Factors of reproduction  

Factors of reproduction are inputs or resources that are used in the generation of goods and services with an aim of making profit.

There are four main factors of production which include;

Land  

Labor  

Capital  

Entrepreneurship  

Land  

This refers to all the natural resources that are available to be used in the production of goods.

These natural resources includes raw materials from the ground, non-renewable resources such as petroleum and renewable resources such as timber.

The income or reward earned from land as a factor of production is rent.

Labor  

This refers to the manpower or work done by human beings.

The value of labor depends on the skills, education and motivation of workers.  

The reward for labor as a factor of production is wages and salaries.

Capital  

This refers to the capital goods, that is, man-made objects that are used for production of goods and services such as machinery, equipment and chemicals.

They also include industries and commercial buildings.

The reward or income earned from capital goods is interest  

Entrepreneurship  

It involves coming up with an idea and developing it into profitable business.

An entrepreneur is therefore an individual who combines the other factors of production to build a business and add the supply in the economy.

The reward or income earned by entrepreneurs is profit.

The first order, reversible reaction A<--> B + 2C is taking place in the membrane reactor. Pure A enters and B diffuses through the reactor. Unfortunately, some of the reactant A also diffuses through the membrane.

A. Plot and analyze the flow rates of A, B and C down the reactor, as well as the flow rates of A and B through the membrane.

B. Compare the conversion profiles of a conventional PFR with those of a membrane reactor. What generalizations can you make?

C. Would the conversion of A be greater or smaller if C were diffusing instead of B?

D. Discuss qualitatively how your curves would change if the temperature were increased significantly or decreased significantly for an exothermic reaction. Repeat for an endothermic reaction.

Into which of the six kingdoms should the organism be placed? Construct a response to state your claim, use evidence, and support with reasoning. Include the list of common characteristics of the kingdom and why it does not belong in the other kingdoms in your justification.

Answers

Answer: The organism is an amoeba belonging to the protist kingdom.

Explanation: The organism cannot be placed in the plantae kingdom because the organism does not contain a cell wall or chloroplasts. The organism also cannot be bacteria or Archaebacteria because it has a nucleus. The organism cannot belong to the fungi or animalia kingdom because it contains psedupodium.

The basic dc-dc converter of Fig. 6-2a has a source of 100 V and a load resistance of 10 ⦠The duty ratio of the switch is D = 0.6, and the switching frequency is 1 kHz. Determine (a) the average voltage across the load, (b) the rms voltage across the load, and (c) the average power absorbed by the load. (d) What would happen if the switching frequency were increased to 2 kHz?

Answers

Answer:

a. 60V

b. 77.46V

c. 600 W

d. there would be no effect when this is done

Explanation:

a.

to get value of average output

Vo = VsD

Vs = 100V

D = 0.6

Vo = 100 V * 0.6

Vo = 60V

Therefore 60V is the value of average voltage

b.

The rms voltage:

= Vs√D

= 100 x √0.6

= 100 x 0.7746

= 77.46V

the rms voltage is Therefore 77.46V

c.

value of average power:

= (RMS)²/R

R = 10

when we put into formula above,

= (77.46)²/10

= 6000.05/10

= 600.005 W

= 600W

d.

If switching frequency is changes to be 2khz it would actually have no effect on the average voltage, average power or rms voltage.
