1) Dean is slowing down on his skateboards. He starts at a speed of 5.5 m/s and slows to 1.0 m/s over a time of 3.0 seconds. What is Dean's acceleration?

Answers

Answer 1

Answer:

Acceleration, A = -1.5 m/s²

Explanation:

Given the following data;

Final velocity, v = 1 m/s

Initial velocity, u = 5.5 m/s

Time, t = 3

To find acceleration;

Acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time. Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Substituting into the equation, we have;

A = (1 - 5.5)/3

A = -4.5/3

Acceleration, A = -1.5 m/s²

Therefore, Dean is decelerating.

Who was the greatest enemy of the Susquehannock?

Answers

The tribe reached their peak of power in the early 1670s and afterward began to decline due to infectious diseases and continued warfare. Drastically weakened by their losses, they were overwhelmed by their long-time enemies of the Iroquois Confederacy by 1678.

The Susquehannock suffered a major defeat by the Iroquois.

Who was the Susquehannock?

The Susquehannock also called Susquehanna or Conestoga. They were  Iroquoian-speaking North American Indian tribe that traditionally lived in palisaded towns along the Susquehanna River in what are now New York, Pennsylvania, and Maryland.

They have been subdivided into several subtribes and clans; the name may have referred originally to a confederacy of tribes. Like other Iroquoian tribes, they were semisedentary agriculturalists.

Throughout the historical period they were at war with the Iroquois, who conquered them in 1676 and forced them to settle near the Oneida tribe in New York.

They were later allowed to return to their former territory along the Susquehanna River. Epidemics steadily reduced their number and in 1763 many of the remaining Susquehannock were massacred by whites.

Is Canada a nation of both peacekeepers and peacemakers? If so, is peacekeeping a myth? If it is a myth, should Canadians try to live up to this myth, or should they abandon it? Explain your responses. . ​

Answers

Answer:

Yes, Canada is a nation of both peacekeepers and peacemakers.

No, peacekeeping is not a myth.

Explanation:

Peacekeepers country often put itself in a position as mediators between other countries that interacted with one another.  Canada has done this several times throughout history (one small example would be when Canada mediate a conflict of imports quota between United States and Mexico).

On top of that, Canada also involved in several peacemakers mission when they sent their resources to help the people who are trapped within political conflicts. (one example of this would be when Canada sent help to  Cambodia during four peace support missions from 1954 to 2000.)

From those historical events alone, I believe Canada could be considered as a nation of both peacekeepers and peacemakers.

Mention the structure of the federal system of government of Nepal.​

Answers

Answer:

Nepal is a geographically diverse country. Since the unification of Prithvi Narayan Shah, Nepal has been implementing a unified form of government. However, this system cannot achieve the country’s development goals and has become a "monopolistic form." Federalism is seen as an inclusive practice in Nepal. Therefore, in view of achieving balanced development across the country through proper allocation and mobilization of resources and reduction of economic, social and religious discrimination, the country has transformed into a federal system.

Since Aswan in 3 AD in 2072, Nepal has become a federal democratic republic. According to the concept of the federal system, Nepal has been divided into 7 provinces. Now each province has a separate government, and the central government also has the federal government.

Explain your answer.
2. What role in an ecosystem is missing from this food web? Explain your answer.

Answers

Answer: 1. Plants

2. Physical factors (sunlight)

Explanation:

1. The plants are the main source of energy for the ecosystem. They exhibit the major amount of energy as they can produce their own food by the process of photosynthesis. Hence, they are called producers. They are consumed by the consumers like rabbits, inchworms, and robins. The producers are at the lowest trophic level in an energy pyramid.  The trophic levels above producers the energy reduces considerably and only 10% energy is utilized in each trophic level.

2. The ecosystem is a biotic community where living beings interact with the non-living components of the environment. Non-living components are water, sunlight, air and others. In this food web the non-living components are absent. The sunlight is the essential non-living component of the ecosystem. It is necessary for photosynthesis, in this the plants use carbon dioxide and water from the environment in the presence of sunlight to produce their food in the form of carbohydrates. So,  the supporting role in terms of non-living components is absent in this ecosystem.

Research an invention in America from the 1800's. Post your invention and a picture on the discussion board. Be sure to include who was the inventor, when it was invented, how it was used and if it is still used today.

Answers

Answer:

Elias Howe Jr. was an American inventor best known for his creation of the modern lockstitch sewing machine. This invetion  was in 1846. The very first lockstitch sewing machine in the world.  His invention helped the mass production of sewing machines and clothing. That in turn revolutionized the sewing industry and freed women from some of the drudgery of daily life at the time. Contrary to popular belief, Howe was not the first to conceive of the idea of a sewing machine. Many other people formulated the idea of such a machine before him, one as early as 1790, and some had even patented their designs and produced working machines, in one case, at least 80 of them.

It was Howe, however, who came up with significant refinements to the design concepts of his predecessors, and on September 10, 1846, he was awarded the first U.S. Patent (4,750) for a sewing machine using a lockstitch design. His machine contained the three essential features common in most modern machines: a needle with the eye at the point; a shuttle operating beneath the cloth to form the lock stitch; and an automatic feed.

Howe's design demonstrated the novel idea of a needle that carried the thread forward, through a piece of material, where another thread, held in a metal shuttle, passed through a loop in the middle thread (caused by the needle moving forward then suddenly backward). The needle was then retracted and this action pulled the two threads to lock them in the fabric. This is how the lockstitch was born.

The sewing machine is easier to use and also you can repair worn, torn or unused clothes by yourself. You can re-design your old clothing. You can even become a fashion trend-setter by making clothes in your own style. Having a sewing machine will save you from going to a tailor, thus helping you to save money.

You wouldn't think the supporters of Andrew Jackson would approve of him him riding on a pig. Also, if you look closely at the cartoon, you can see the words bribery, fraud, and plunder, and there are even skeleton heads on the ground next to him. Once again, Jackson's supporters (the Democrat-Republican Party) would not approve of this on his statue, so the political party that most likely approved of this cartoon, is the National Republican Party.
