1. When using the fixed pulley, the weight of the fixed pulley is borne by the structure of the fixed pulley, such as the rope, so its weight does not need to be considered.
the weight of the movable pulley is a part of the whole lifting weight, and of course it needs to be calculated

2. ATP is not only an energy storage material, but also an energy supply material. The content of ATP in living cells is very small. ATP and ADP can rapidly transform into each other. Because the high-energy phosphate bond in ATP is easy to hydrolyze and synthesize, a large amount of energy is released ring hydrolysis for life activities, Therefore, ATP is referred to as the "energy currency" of organisms on the basis that the mutual transformation of ATP and ADP can realize the storage and release of energy.

1. I haven't been to Moulin Rouge, but I want to go according to my own interests.
2. How can the so-called deep tour be only 1.5 hours and 4 days is not enough? It's a lie. It's estimated that I will take you to some souvenir shops.
3 The Seine River is supposed to be a cruise to see the scenery. This project could have gone, but it's not very interesting to ask how long the cruise takes, if it's only a short time.
4. It's good to go to Versailles Palace.
5. The scenery of Pisa is very general. Only the leaning tower is famous for its three white buildings: the leaning tower, the leaning tower, the leaning tower If you go to Pisa, you'd better have a look at the church and another building.
6. If it's an authentic gondola, 30 euro is not expensive. It also depends on the route and time of the cruise ship. If it's going through the alleys of Venice, it's still very interesting.
7 I've never been to Interlaken's Jungfrau. It seems that 140 euro is a bit expensive. I went to Chuge peak in Bayern, Germany, but the price is not so expensive. The cableway is about 35 Euro one way, but it's ok if the cost of renting ski equipment is included.
8. Of course, you can shop freely. If you are in Paris, you can find some ty-free shops by yourself (there are many in Paris, It's much cheaper, and some shops are equipped with Chinese waiters. Several people can buy them together, and they can bargain with each other.
for the Musee d'Orsay in Paris, I think it's also necessary to go to the Musee d'Orsay, which is full of works of modernist painters, such as Van Gogh, Monet, etc Manet's paintings are inexpensive and can be photographed, while those in the Louvre are only classical paintings

published at 09:54, March 6, 2014; Notre Dame de Paris (cath) é Drale Notre Dame) recommended level 10
needless to say, this is a very famous scenic spot. You must see it when you come to Paris. What makes him famous all over the world is, of course, Hugo's novel, the romantic love story of Notre Dame's bell tower freak and the beautiful gypsy girl Esmeralda. This classic plot is also perfectly interpreted into a film by director Jean delanova. So I suggest you read novels or movies before you come here to increase your understanding of scenic spots. This is the first Gothic building in Paris and a masterpiece of French Gothic architecture. Notre Dame is famous for its three arches. The central arch describes the "final judgment" of Jesus in heaven. The oldest statue of the Church (1165-1175) is located in the right arch, which describes the story of St. Anne and the baptism of bishop sully for Louis VII (who ordered the construction of Notre Dame in the 12th century). On the left is the virgin's portal, which depicts the resurrection of the virgin, surrounded by saints and angels. Above the arch is the Galerie des ROIs, which displays statues of 28 kings of the Old Testament. The interior of the church is decorated with beautiful stained glass windows, which can be seen from the north gate. One of the most eye-catching circular windows, about 10 meters in diameter, is commonly known as rose glass window. The glass window depicts biblical stories. The column on the north side of the church is the famous "Notre Dame of Paris". After seeing the interior of Notre Dame, we can also go to the bell tower of Notre Dame. Here is the habitat of the grotesque people in the bell tower. You can see many statues of the grotesque people in the bell tower and huge clocks. Some people think that this is the best place to see the panoramic view of Paris in the daytime. Some people think that it is the Pompidou National Center for culture and art. Different people have different opinions on this point. In short, the clock tower is worth seeing
tips: if you want to go to the bell tower, you need to wait in line, and it takes a long time to get ready: Church takes one hour, bell tower takes one and a half hours

the 12 streets in Paris are centered on the Arc de Triomphe, radiating all around, which is a magnificent example of the design of big cities in Europe. So on the Arc de Triomphe, there is a feeling of king in Paris

Eiffel Tower. The reason why we recommend you to come to the Eiffel Tower in the evening is that the night view of the Eiffel Tower is really good, and the Eiffel Tower is full of star lights at night. Finally, the Eiffel Tower is one of the few scenic spots in Paris that open late into the night. When you come here at night, not only the scenery is unique, but also the schele is saved. Eiffel Tower the Eiffel Tower has been built since 1887. It is divided into three parts, 57.6 meters, 115.7 meters and 276.1 meters above the ground. There are restaurants on the first and second floors, and a viewing platform on the third floor. There are 1711 steps from the tower base to the top. The Eiffel Tower is one of the symbols of Paris and is called "Iron Lady" by the French. Together with the Empire State Building in New York and the Tokyo Tower, it is known as the three famous buildings in the West
note that the Eiffel Tower goes up and down by elevator (of course, there are stairs. Those who like to challenge themselves can try...) The waiting time for elevator tickets is very long. It takes about half an hour to one hour. The elevator can go to the second floor or climb to the top. I suggest you go to the second floor first. It's very good to see the night view of Paris here. When you get to the second floor, you can buy tickets to climb to the top. There are few queues here.

Personally, I think there are many interesting places for Paris, and the Eiffel Tower is the most popular place. In addition to here, there are Notre Dame of Paris and other churches with obvious religious flavor, or walking in the ancient streets of Paris and so on, which are very good choices because Paris is also a city with a very long history, many places here have a long history, so you won't be disappointed to visit
Paris is a city with a long history, strong European style, enthusiastic people and so on. Many people's memory of Paris lies in these aspects rather than building attractions
8. Louvre, Eiffel Tower, Arc de Triomphe, Notre Dame

1. Eiffel Tower
the Eiffel Tower, named after its designer Eiffel, was built and completed in the midst of numerous objections. It is famous all over the world for its height, construction art and its bearing significance of commemorating the victory of the French Revolution and welcoming the Paris International Expo. Now it is actually one of the landmark buildings in Paris, and even some countries have begun to follow suit
the colorful marble walls are dazzling; Giant crystals pour down like waterfalls; The western-style oil paintings on the inner wall and the dome of the palace seem to tell the great achievements of the kings in the past, and the fairy tales in the oil paintings are vividly told
to the west of the palace is a well repaired French Park, which stretches for 3 kilometers. The beautiful scenery in the garden, with one flower, one grass, one water and one pool, is amazing. It is worthy of "the park of horse runners"
10. It's two years since I graated from high school, but remember that there was a fierce man in our school who could run 14 seconds in the semifinals of 100 meters? It should be no problem
