Let s help me figure out a good idea 50

You are not of Han nationality, I don't know how much difference there is between our two nationalities, we think that there is no mother in the world who does not love her children, your sister is gone, this is a fact, you can hide it for a while, you can't hide it for a lifetime. I think your sister's death has nothing to do with you, even if there is, death won't solve the problem. Your death will only make your mother sadder.

Running away won't solve the problem, the more you run away, the more it follows you, and when you face it bravely, it no longer exists. Go home when you feel homesick!

I think your sister's death must have something to do with her boyfriend, and maybe it has something to do with this society. This society is too dark, two little girls are alone in the rivers and lakes, how difficult it is, please ask a few brothers upstairs to give some understanding!

The customs of different ethnic groups are really different. Is it possible that your mother blocked you from society because of your sister's death? It shows that your mother is a very feudal woman, and she is very sad!

You don't have to go home. People are so old, we Han people are like this, we should learn to take care of ourselves at the age of 18. So you can create your own world! Really, you can.

Do you say that you will have no friends, then you can add me, me. Just write "know" then.

This, I don't think you can do this, you can't help but let your mother know when your sister dies, after all, it's her daughter, I don't know what nationality you are from, but I think no matter which nationality your daughter died, your mother should have the right to know. And now for your own sake, isn't it a little too selfish for you not to even tell your mother about such a big thing as your sister's death? One more point, why wouldn't you have a boyfriend if your mom knew your sister had passed away, and you wouldn't have friends?

Is it true that if the elder sister of your nation dies, the younger sister is not allowed to leave the house again?

Why did your mother know that your sister was dead, and you didn't even have the most basic right to make friends? The deceased is gone, why bother with it, let's be honest and tell your mother You shouldn't be too young to be outside with your sister If your mother is really that kind of to you, you should know that you should know the rebellion And the death of a loved one What a big deal this is How can you hide it? Does your mom like your sister that much?

If it were me, I would definitely not be like you, I know how to fight, I also know how to resist, and I can tell the weight of the matter more clearly Now my mother's blame is not a problem It's your sister's matter that is more important, don't you understand I really don't know what you think.

You still have to tell your parents the truth, you can't die, and if you die, then your parents have no hope. They're so old, they still need you to take care of them! You should fulfill your mission.

There are two things that I don't understand.

1.Why didn't your mother let you go home when your sister died? Now that you have lost one daughter, don't you want the other too?

2.What does your sister's boyfriend have to do with the whole thing?

It's terrifying! You'd better make it clear to your mom. After all, this matter cannot be hidden for a lifetime.

Home is always a safe haven.

Sometimes, you have to bear it too.

yes, I don't understand what's going on.

Why did your parents not know why your sister died?

And your sister's boyfriend, what the hell is going on with them???

How do you do it like a detective.

The unit price of turf in Figure 1 is: 5000 (x 2-2*2mx+4m 2); Figure 2: The unit price of turf is: 5000 (x 2-4m 2).

Fig. 1, Fig. 2 The ratio of the unit price of the two ways of purchasing turf is:

5000/（x^2-2*2mx+4m^2）：5000/（x^2-4m^2）=1/（x-2m)^2:1/(x-2m)(x+2m)=(x+2m):(x-2m).

1.The distance of the end of the rope calendar jujube = 10 2 = 20MW total = FS = 60N * 20m = 1200J

Yes=gh=100*10=1000j

3.Mechanical efficiency = w has royal town limb dismantling w total * 100%.

The most important mechanical means of transportation in human history, in the early days, was called a steam locomotive, also called a train. There are independent tracks. Railway trains can be divided into freight cars and passenger cars according to the load; There are also vans that combine both.

One of the major disadvantages of the coal-fired steam locomotives, which were the first to use coal-fired steam power, was that they had to set up facilities for adding coal and water along the railway lines, and they also spent a lot of time adding coal and water to the locomotives during operation. These are all very uneconomical. At the end of the 19th century, many scientists turned to the study of electricity and coal-fired steam locomotives.

The world's first steam locomotive to actually run on rails was designed by Charlie Trivisik, an engineer from Conwall. Its train, which had four power wheels, was tested on February 22, 1840, at a speed of 20 kilometers per hour when empty and 8 kilometers per hour (equivalent to the speed of a person walking briskly) when loaded. Unfortunately, the weight of the train crushed the tracks.

Electric locomotive In 1879, the German Siemens Electric Company developed the first electric locomotive, which weighed about 954 kilograms, and only performed once at the first exhibition in Berlin. On October 27, 1903, the first practical electric locomotive developed by Siemens and General Electric was put into use. Its speed reaches 200 pounds per hour.

Fuel locomotiveIn 1894, Germany successfully developed the first gasoline diesel locomotive. And it was applied to rail transportation, ushering in a new era of diesel locomotives. However, this kind of locomotive burns gasoline, which is too expensive and not easy to promote.

In 1924, Germany, the United States, France and other countries successfully developed diesel locomotives, which were widely used in the world.

In 1941, Switzerland successfully developed a new type of fuel turbine locomotive, which was fueled by diesel. And the structure is simple, the vibration is small, and the operation performance is good, so it is widely used in industrial countries.

Since the 60s of the 20th century, countries have vigorously developed high-speed trains, such as the high-speed train from Bartos to Lebanon in France, with a speed of 260 kilometers per hour; The high-speed train from Tokyo to Osaka in Japan also reaches more than 200 kilometers.

People are still not satisfied with such high-speed trains. France, Japan and other countries took the lead in developing maglev scattered trains. China is also building the world's first commercial maglev train line in Shanghai. The train is suspended on the tracks and can reach speeds of up to 400,500 kilometres per hour.
