If something goes wrong, my brothers and sisters will come and help me solve the problem

Having hepatitis B is not very good. It's hereditary.

But now there are a lot of people in China who are carriers of hepatitis B. At least 100 million.

So, ah. I think. It's a shame if it's because of this separation.

Where can I find a suitable girlfriend? I want to start a new relationship again. How tired.

Do more ideological work for the family. I think your parents will respect your choice.

It is very troublesome to oppose it at home, and the first thing to do is to have a correct understanding of this disease.

Whether it's hereditary or not, then choose well.

To love her is to tolerate everything she has, and even be willing to lose everything yours.

This kind of thing will definitely not be accepted by the family, because it will affect the health of the next generation! I'm a girl and I have a boyfriend too. Let me share my personal opinion.

If this were the case for my boyfriend, I would still be with him or even marry him, because I love him, but I can't have a baby after marriage, because it's not fair to the baby! The feelings of two people are in their own hands, you can't have both, you don't want a baby to adopt a baby, and you will be happy! It's just why would you want to tell your family?

You can choose white lies, don't let your family worry about you, and you will choose happiness! It's up to you, if you care if she's sick then I can't help it!

This matter has to be carefully considered to avoid trouble in the future, think of all the bad things, if you really love her, accept her, and don't dislike her in the future, after all, this is a lifelong event. Don't have conflicts after marriage and hurt each other.

If you reject him for this matter, it means that you don't really want to be with him. It's as simple as that, and it's not earth-shattering.

1. Problems that should be understood in the experiment of leverage equilibrium conditions:

1) Before the experiment, adjust the nuts at both ends of the lever so that the lever is balanced in a horizontal position. The purpose of this is that the arm can be easily read out from the lever. It avoids the inconvenience of measuring the force arm when the lever is balanced in the inclined state.

2) When the lever is balanced, if the power and resistance are on both sides of the lever fulcrum, the direction of the power and resistance is the same; If the momentum and resistance are on the same side as the lever fulcrum, the momentum and resistance are in opposite directions.

2. Matters that need to be understood in the process of solving leverage problems:

1) Problem solving guidance: To analyze and solve the problem of leverage balance conditions, a leverage diagram must be drawn; Find out the magnitude and direction of the force and the size of the force arm; Then, according to the specific situation, the specific analysis is carried out to determine how to use the equilibrium condition to solve the relevant problems;

2) Solve the problem of the least power when the lever is balanced: in this kind of problem, it is generally: the resistance arm is a certain value, to make the power force minimum, the power arm must be maximized, and the power arm needs to be maximized

Find a point on the lever so that the distance from this point to the fulcrum is the farthest;

The direction of the force should be the direction that crosses the point and is perpendicular to the line between the point and the fulcrum.

3) Use the extreme value method to judge whether the balance of the lever is broken: the so-called extreme value method (also known as the extreme thinking method) is a thinking method of analysis, reasoning and judgment from a certain limit state.

I hope it helps you, and if you have any questions, you can ask them

I wish you progress in your studies and go to the next level! (*

Experiment Name: Equilibrium Conditions for Leverage.

Purpose of the experiment. 1. Through this experiment, let the lever balance in the horizontal position, and understand the scientific idea of designing the experiment.

2. Obtain the lever balance condition: power power arm = resistance resistance arm f1 l1 = f2 l2

3. Be able to understand the basic meaning of the state of leverage equilibrium.

Experimental equipment: levers, brackets, a box of hook codes, hanging rings fixed to the levers, spring dynamometer.

Experimental requirements: 1. Assemble the lever, ** the equilibrium condition of the lever.

Experimental steps: The first step is to install the lever on the bracket so that it can rotate around the fulcrum flexibly, adjust the balance nuts at both ends of the lever, so that the lever is in a horizontal stationary state, and the lever is horizontally stationary.

The second step, first on the left side of the fulcrum, 20cm at a hook code, try to hang a few hooks at the right side of the 10cm, can make the lever once again horizontal stationary, after the lever is horizontally stationary, the experimental data is filled in the experimental record, the force acting on the left side of the lever, as the power f1, then f1 =, the power arm l1 is 20cm, f1 l1 = 10

The force acting on the right side of the lever is f2, f2 = 1n, the resistance arm l2 is 10cm, f2 l2 = 10

Change the position of the hook code and the number of hook codes, and do another experiment,)

The third step, the fulcrum on the left side, 5cm away from the fulcrum, hang 3 hook codes, try it, 15cm on the right side of the fulcrum, you need to hang a few hook codes to make the lever horizontal static again.

After the lever is balanced in the horizontal position, fill in the experimental data in the record **, the power f1, f1=, the power arm L1 is 5cm, F1 L1=, the force acting on the right side of the lever is F2, F2=, the resistance arm L2 is 15cm, F2 L2=

The fourth step is to conduct comparative analysis through the experimental data recorded twice, and know that when the lever is balanced, the power arm = resistance arm.

f1×l1=f2×l2

Conclusion: a. The equilibrium state of the lever means that the lever is in a constant rotation state, or a stationary state, and the position at rest is not necessarily in the horizontal position.

b. When the lever is in equilibrium, the power arm = resistance arm.

Hello: This has constituted the constitutive elements of the crime of extortion. The crime of extortion refers to the use of threats or coercion against the victim to forcibly demand public or private property for the purpose of illegal possession.

In our country, only legal marriages, that is, marriages with marriage certificates, are marriages protected by law. Marriage contracts are not protected by law in our country. So the other party's request is unreasonable.

If this happens again, you can report the case to the police station of the Public Security Bureau. If the public security bureau does not file a case, it may file a private prosecution with the people's court and request legal assistance.

I hope mine is helpful to you and I wish you a good mood every day :)

Isn't this what a robber does, what are you leaving him to do, you have to use the law to protect your interests.

You can sue them, because the marriage contract is not protected by law in our country.

First of all, it's best to record when they threaten you, and tell you when you're done!

The average score of the Little Red match is 35, and the average score of the Xiao Ming match is 34.

Xiao Ming's first two times were lower than Xiao Hong.

The scores of the two have improved each time.

The two of them jumped farther and farther each time.

Solution: Set the box body with x sheets, and make the bottom of the box with Y sheets.

Analysis: Because there are now always 150 tin box bodies and bottoms. So x+y=150

Formula; The number of sheets of the body of the box + the number of sheets of the bottom of the box = the total number of sheets of white iron sheets made of canned food boxes 150Equation (1) is derivedAnd because now a box body and two box bottoms are matched to form a set of canned food boxes.

So; The number of boxes * 2 = the number of boxes at the bottom. This will make them equal. Equation (2) 2*16x=43y

x+y=150 (1)

2*16x=43y (2)

150-y=x (3) from (1).

Substitute (3) for (2);

32(150-y)=43y

y=64 and y=64 are substituted into (1) to get: x=86 so; x=86

y=64 Answer: Use 86 sheets to make the body of the box, and use 64 to make the bottom of the box.

Suppose x sheets make the body of the box, and Y sheets make the bottom of the box.

x+y=150 16x=y43/2

So y=16x*2 43

x+x*32/43=150

x=86y=150-86=64

Use 86 sheets for the body of the box and 64 sheets for the bottom of the box.
