3 0

Answer:

Potential energy is energy that is stored in a person or object.Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). Elastic potential energy is due to an object's shape. It results when an elastic object is stretched or compressed.

Write an essay on the great wall of china​
Alona [7]
The Great Wall of China is one of the greatest architectural achievements ever recorded in history. The Great Wall translates to “long fortress.” The wall was made entirely by hand. It was built to protect the Chinese from intruders from different Nomadic Tribes. The wall is about 5,500 miles long. The wall did not stretch across all of China but it stretched from Shanhaiguan in the East to Lop Nur in the West. Some people say that you can even see the wall from the moon! Wouldn’t that be something to see? The wall is very old and has been around for about 2,000 years. Parts of the wall are missing from it decaying and crumbling. Despite parts of the wall missing it remains a popular attraction today and is one of the seven spectacular…show more content…
During the Ming dynasty (1368-1644) was when much most of the wall was added. The Mind dynasty suffered from their attackers the Dadan, Nuzhen, and Tufan tribes. The Ming court built a lot more walls in the north as an attempt to keep out the attacking tribes. They built the walls much more elaborate and durable than the Qin Dynasty. There were many walls, fortresses, and watch towers along the wall which made the country more successful. Even with all the new construction on the wall the Ming dynasty was defeated by the Oirats in the battle of Tumu in the year 1449. The Ming dynasty had failed to keep the Mongolian and Manchurian tribes under control and it had weakened the Ming Empire. After the Mings loss in this battle they built more walls to make them less vulnerable if they were attacked. Towards the end of the Ming dynasty the Great Wall helped a lot to defend them from the Manchu invaders. The Manchus got into Beijing through the Shanhaiguan gates and took over the city ending the rule of the Ming dynasty and starting the new rule of the Qing Dynasty. The Qing Dynasty extended Chinas territory farther north beyond the Great Wall. The wall didn’t protect China’s border anymore so, construction on the wall stopped and soldiers abandoned their posts on the wall. The wall wasn’t used again after.
Today, the Great Wall is still standing in some parts but people fear that itthe Great Wall] demonstrates the manifestation of the wisdom and tenacity of the Chinese people.”(cortland.edu). China is considered one of the world’s oldest civilizations with the first dynasty beginning in 221 B.C.. A famous icon of this great civilization is the Great Wall of China, or known to the Chinese as Wan Li Chang Cheng. During the Warring States period, many feudal societies built their own sections for security. Eventually the walls were connected and there was a unified China. With The Great Wall of China is known as the largest construction project to be put in effect in all of world history. The wall, also known in China as "long wall of 10,000 li," is a collection of numerous short walls extending along the crest of hills on the southern edge of the Mongolian plain. Although it is a common misconception that the Great Wall of China is one long continuous wall, it 's structural inconsistency in no way undermines its greatness. The wall has been built, destructed,includes modules of ________ so you can see the construction of _____ Today I am going to be presenting the Great Wall of China and what political and military reasons it was built for. The construction was a feat of great magnitude and reflected the innovations and technological advancements of the Ancient Chinese. The reason I have decided to focus upon the Ancient Chinese is because I find China a very interesting civilisation. The ancient Chinese civilisation began 7,000 to 8,000 years ago and about

lightning is actually an enormous display of the concept of A.chemical heating B.solar energy C.magnetism D.grounding
allsm [11]

Answer:

D) Grounding

Explanation:

The potential difference between cloud and ground leads to ionization of the atmosphere and resulting conduction through the air often to ground (although it can be between clouds at different potentials. I would say grounding, like the spark when you touch a hot battery terminal to ground on a car.

A ball is thrown straight upward and rises to a maximum
Leviafan [203]

Answer:

Explanation:

As we know that the ball is projected upwards so that it will reach to maximum height of 16 m

so we have

v_f^2 - v_i^2 = 2 a d

here we know that

v_f = 0

also we have

a = -9.81 m/s^2

so we have

0 - v_i^2 = 2(-9.81)(16)

v_i = 17.72 m/s

Now we need to find the height where its speed becomes half of initial value

so we have

v_f = 0.5 v_i

now we have

v_f^2 - v_i^2 = 2 a d

(0.5v_i)^2 - v_i^2 = 2(-9.81)h

-0.75v_i^2 = -19.62 h

0.75(17.72)^2 = 19.62 h

h = 12 m

A baseball travels 200 metes in 6 seconds, what is the baseball’s velocity?
goldenfox [79]

Answer:

33.33 m/sec

Explanation:

A baseball travels 200 metes in 6 seconds,

what is the baseball’s velocity?

use the formula: velocity = distance over time

where (d) distance = 200 m

and (t) time = 6 sec.

plugin values into the formula:

v = d / t

  = 200 m / 6 sec

  = 33.33 m/sec.

therefore, the baseball's velocity is 33.33 m/sec

Explain the difference between the synodic period of a planet and the sidereal period. why is the synodic period often much less
Ilia_Sergeevich [38]
-Synodic period is the period of celestial bodies observed on the moving planet(mostly earth)
Sideral period is the period comparing to the fixed stars without motion of the earth involved.

(I will explain the second question with an example, so it's easier to understand)
-For Sideral month for example of the moon it cactually complete one revolution in around 27.3 days.
However, since the earth moves, for us it took some more time to see the moon the same as before (fullmoon to fullmoon) again. That make synodic month of the moon to be around 29.5 days.
