Having good form means expending just the right amount of energy during a sport or activity. Think about the sport you chose. Give an example of how poor form can use too much of your energy during the activity. What happens when that energy is gone

Answers

Answer: An example is football, when footballers experience poor form, most times due to injury or weight gain, they become lethargic

Explanation:

Poor form can be frustrating, you put in much energy but little or no result to show. An example is football, when footballers experience poor form, most times due to injury or weight gain, they become lethargic, they put in much energy but are still slow. They'll need to do more exercise or improve game plan to boast their game and in turn convert energy to gain.

Answer:

One example of poor form in long-distance running is dropping a hip and rocking side to side as you run. A person’s hips carry a lot of the body’s weight. It takes energy to move them. The goal of running is to move forward. If your hips are going dropping or rocking side to side, that is energy that could be used to move yourself forward. It’s wasted energy. If you use up that energy, you’ll get tired a lot quicker.

The speculative demand for holding money is when people hold money:
Group of answer choices

a: to take advantage of changes in interest rates.

b: as insurance against unexpected needs.

c: to transact purchases they expect to make.

d: to speculate in the stock market.

e: instead of near money.

Answers

Answer:

a: to take advantage of changes in interest rates.

Explanation:

In economics or financial accounting, money can be defined as any asset used by an individual or business entity to make purchases of goods and services at a specific period of time.

Simply stated, money refers to any asset which can be used to purchase goods and services by customers.

This ultimately implies that, money is any recognized economic unit that is generally accepted as a medium of exchange for goods and services, as well as repayment of debts such as loans, taxes across the world.

John Maynard Keynes was a British economist born on the 5th of June, 1883 in Cambridge, England. He was famous for his brilliant ideas on government economic policy and macroeconomics which is known as the Keynesian theory. He later died on the 23rd of April, 1946 in Sussex, England.

According to John Maynard Keynes, the three (3) desires governing the need for money are;

I. Transactions demand.

II. Precautionary demand.

III. Speculative demand.

In Keynesian economics, speculative demand for money can be defined as a desire or need to hold money for the sole purpose of investing it in assets other than those necessary for living.

This ultimately implies that, the speculative demand for holding money is when people hold money to take advantage of changes in interest rates while waiting for better market conditions.

Name a company that seems large but might be classified as small because it has relatively little impact on its industry.

Answers

Answer:

Name a company that seems large but might be classified as small because it has relatively little impact on its industry.

The Motors T, Inc. Despite having sales that exceed $200–300 million annually, they barely make any impact on the economy. They appear to be a huge corporation but are actually considered little because they have little impact on their industry.

Which companies can be classified as small-size companies?

The number of workers in the manufacturing sector is used to calculate as an indicator. A legal entity that has the authority to conduct business on its own, such as the ability to sign contracts, own property, amass debts, and open bank accounts, is said to have an enterprise.

According to their size, businesses can be categorized into a variety of groups; the most common criterion used for this is the number of employees. Less than 250 individuals work for small and medium-sized businesses (SMEs).

SMEs are further split into micro enterprises (less than 10) small enterprises (between 10 and 49), and medium-sized enterprises (between 50 and 99 people) (50 to 249 employees). 250 or more workers are employed by large businesses.

The assertion that non- formal institution have no role to play at the processing stage of the system theory is a empty rhetoric . Comments

Answers

Answer and Explanation:

Systems theory refers to how natural and man-made systems are formed and how these systems interact with each other as needed. During the creation of these systems, the theory presents a processing stage. At this stage the limitations and objectives of each system are defined and it is exactly at this stage that non-formal institutions are so important. This is because the limitations and objectives of a system directly depend on the creation of rules, concepts, values and ideas that make up a society, especially in artificial systems created by human beings. These rules, concepts, values and ideas that society expresses are formed by non-formal institutions. In this case, we can say that it is not correct to say that non-formal institutions have no role to play in the processing stage of systems theory.

In psychoanalysis, June's therapist suggests that she is taking her unconscious childhood anger at her father out on her husband by picking silly fights with him. June starts crying and says that her therapist is the only man who has ever really understood her. In this example, the therapist suggested that June was engaging in the defense mechanism of _____ and June's reaction illustrates _____. Group of answer choices reaction formation; displacement projection; transference repression; displacement displacement; transference

Answers

Answer:

1. projection;

2. transference

Explanation:

Considering the situation that was described above, it is apparent that the therapist suggested that June was engaging in the defense mechanism of PROJECTION and June's reaction illustrates TRANSFERRENCE.

This is because Projection in psychoanalysis is a form of defense mechanism whereby disliked feelings and characteristics towards an individual are disputed and attributed to another person.

Also, given that Transferrence is a psychoanalytic issue, whereby feelings individuals had in past, usually common during childhood towards their parents, are in a way transferred to the present situation.

In this case, June was transferring her projected dislike feelings and characteristics she has for her father towards her husband unconsciously

Briefly summarize the arguments for and against animal experimentation?

Answers

Answer:

ARGUMENTS FOR AND AGAINST ANIMAL EXPERIMENTATION

For

1. Animals have always been used for experiments that are considered dangerous for humans, e.g lab rats.

This is necessary as some procedures are considered too dangerous for a human to undergo, and therefore, an animal is used to test the process.

2. Animals cannot talk, therefore, have no rights.

Animals, though living, do not have and enjoy the same rights that humans do according to the Universal Declaration of Human Rights. This makes it possible to subject them to experiments because no rights are being infringed upon.

Against

1. It is unethical and inhumane to use animals for experiments

Animals have feelings and as such should not be used for unsafe experiments. The practise is inhuman and unethical as it is done without the consent of the animal.

2. Animals are living things and so they have rights.

Animals are living and such should be considered to have rights just as humans do and it would be wrong for any scientist to get any animal of his choice to perform experiments.

What is the slave trade?In the fifteenth century, Portugal evolved into the first European nation to carry a considerable part in African slave trading. The Portuguese especially acquired slaves for struggle on Atlantic African island plantations, and the latest for farms in Brazil and the Caribbean, though they also sent a smallish number to Europe.For better than 2,000 years people in numerous different parts of the world have moved their fellow humans into slavery. Between about 1500 and 1900, Europeans forcibly uprooted millions of individuals from throughout West Africa and West Central Africa and dispatched them across the Atlantic in circumstances of great cruelty.

Gettysburg Address

"Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract.
The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth." - Abraham Lincoln

Answer:

"Our nation was created based on freedom and the concept that all men are equal." (First sentence of the first paragraph)

"Our men, with great courage, living and dead, fought to ensure that these concepts were respected." (Seventh sentence of the first paragraph.)

"In honor of the men who fought, we must give this nation a new beginning, where everything is done for the people, which is the most important thing we have." (Second sentence of the second paragraph.)
