Answers

Answer 1

Complete question :

A driver of a car moving with speed 90km/h saw a child on the road 25m ahead of him .he jammed on the brake and bought the car to rest. Calculate the time taken to bring the car to rest and retradation of the car.

Answer:

t = 2 seconds ; retradation = - 12.5 m/s²

Explanation:

Given that :

Final velocity v = 0

Initial Velocity u = 90 km /hr = (90 * 1000)m / 3600s = 90000m/3600s = 25m/s

Distance = 25 m

Using the relation :

v² = u² + 2aS

where, S = distance covered a = retradation

0 = 25² + 2a(25)

0 = 625 + 50a

50a = - 625

a = - 12.5 m/s²

Time taken (t) :

Using :

v = u + at

0 = 25 + (-12.5 * t)

0 = 25 - 12.5t

12.5t = 25

t = 25 / 12.5

t = 2 seconds

. B. supported the Ottoman Empire in its efforts to keep Serbia under its control
C. broke its military alliance with Germany, which had refused to condemn the Serbs.
D. joined the Triple Entente to defend itself from future Serbian attacks.​

Answers

Answer:

A. used the attack to justify taking aggressive action against Serbia

Explanation:

Austria-Hungary sent them an ultimatum to Serbia, and Serbia agreed to most of it but the only part it didn't agree to was that Austria-Hungary was able to do an investigation of who did the assassination in which Serbia refused for Austria-Hungary to investigate. This then went to the German's in which they backed Austria-Hungary for being an ally in the war which then led to the out-break of world war 1.

Answer:

Correct answer is A. used the attack to justify taking aggressive action against Serbia .

Explanation:

Option A is correct because after the  assassination on June 28th 1914, Austria-Hungary declared war on Serbia on July 28th, starting a great offensive on its western and northern boundaries.

B is not correct as Ottomans entered the war in later stage, and Serbia was not their territory.

C is not correct as Germany stayed on the side of Austria-Hungary.

D is not correct as Triple Entente fought against Austria-Hungary in this war.

Machiavelli’s The Prince

Complete and submit this assignment by the due date to receive full credit.

(50 points)

Directions: Read the excerpt from Niccolo Machiavelli, The Prince (1513) and answer the essay prompt highlighted below

Note:

Machiavelli hoped to impress, and get a job working for the powerful Medici family in Florence with this work on politics. It didn’t work, but it has proved to be a much loathed and admired analysis of human affairs from a coldly realist point of view. When Machiavelli speaks of a “prince,” he does not mean the son of a king, but is using the word in its older meaning “the first,” or the ruler of a territory. Italy was divided into many small city-states and other domains, which were in constant competition with each other.

From Chapter 17: On cruelty and compassion, and whether it is better to be loved than to be feared, or the contrary

Descending next to the other qualities mentioned before, I say that each prince ought to desire to be believed compassionate, and not cruel, nonetheless he must be alert not to use this compassion badly. Cesare Borgia was believed cruel; nonetheless, that cruelty of his restored the Romagna, unified it, and led it back to peace and to faith . . .

A prince, therefore, must not care about the infamy of cruelty in keeping his subjects united and faithful, because if he makes a very few examples, he will be more compassionate that those who, through too much compassion, allow disorders to occur from which arise killings and robberies. For the latter usually harm an entire population, but those executions that come from the prince harm a particular person . . .

From the above a debate arises whether it is better to be loved than feared or the contrary. The answer is that one would want to be both the one and the other, but because it is difficult to join them together, it is much safer to be feared than loved, if one has to do without one of the two. For the following may be said generally about men; that they are ungrateful, changeable, pretenders and dissemblers, avoiders of dangers, and desirous of gain, and while you do them good they are wholly yours, offering you their blood, their property, their life, and their children, as I said above, when the need is far off, but when it comes close to you they revolt. And that prince who has founded himself wholly on their words, because he finds himself naked of other preparations, is ruined. For the friendships that are acquired at a price, and not with greatness and nobility of spirit, are paid for but they are not possessed, and when they come due they cannot be used. Men have less fear of offending one who makes himself loved than one who makes himself feared, since love is held in place by a bond of obligation which, because men are wretched, is broken at every opportunity for utility to oneself, but fear is held in place by a fear of punishment that never abandons you…

Nevertheless, the prince must make himself feared in such a way that, although he does not acquire love, he avoids hatred; because he can endure very well being feared whilst he is not hated, which will always be as long as he abstains from the property of his citizens and subjects and from their women. But when it is necessary for him to proceed against the life of someone, he must do it on proper justification and for manifest cause, but above all things he must keep his hands off the property of others, because men more quickly forget the death of their father than the loss of their patrimony. Besides, pretexts for taking away the property are never wanting; for he who has once begun to live by robbery will always find pretexts for seizing what belongs to others; but reasons for taking life, on the contrary, are more difficult to find and sooner lapse. But when a prince is with his army, and has under control a multitude of soldiers, then it is quite necessary for him to disregard the reputation of cruelty, for without it he would never hold his army united or disposed to its duties.

Answer:

Niccolò Machiavelli was an Italian Renaissance political philosopher and statesman and secretary of the Florentine republic. His most famous work, The Prince (1532), brought him a reputation as an atheist and an immoral cynic.

Machiavelli believed as a ruler, it was better to be widely feared than to be greatly loved; A loved ruler retains authority by obligation while a feared leader rules by fear of punishment. In it, Machiavelli outlined his vision of an ideal leader: an amoral, calculating tyrant for whom the end justifies the means. The Prince not only failed to win the Medici family's favor, it also alienated him from the Florentine people.

Clearly a Renaissance man, Machiavelli showed his greatest skill and made his most lasting mark on history as a writer. He wrote histories, short stories, and even plays. The Prince, however, was Machiavelli's most influential work. It was an examination of how a leader could gain power and stay in power.  

The general theme of The Prince is of accepting that the aims of princes – such as glory and survival – can justify the use of immoral means to achieve those ends. From Machiavelli's correspondence, a version appears to have been distributed in 1513, using a Latin title, De Principatibus (Of Principalities).

The author's name has been lent to a style of leadership and management associated with cynicism, deceit and guile. To be described as Machiavellian is to be insulted — it means being duplicitous, egocentric and manipulative. The Machiavellian is exploitative, competitive, and selfish.

Ptolemy's map of the world is the earliest among the listed advancements as it dates back to the 2nd century AD. It provided an important reference for European explorers as they ventured into unknown territories.

The establishment of the first school of oceanic navigation, such as the School of Sagres in Portugal, occurred during the 15th century. These schools aimed to train navigators and improve their knowledge and skills in oceanic exploration.

Portuguese caravels with triangular sails were developed and widely used by Portuguese explorers in the 15th and 16th centuries. This innovative sail design allowed ships to navigate more efficiently against the wind, enabling longer voyages and greater exploration possibilities.
