My Identity As A Schoolmaster Has Been Exposed

Chapter 125: Too Outrageous

His faint voice came from Xu Cong’s bed: “I didn’t sleep. I listened to what you said. It doesn’t matter what I choose, but what you choose.”

Several roommates raised their ears and asked: “Do you have any good suggestions?”

Xu Cong thought for a while, and said, “You should learn from your own actual situation and learn from your strengths. The most important thing is to be able to go to university! Leave liberal arts and sciences alone!”

Sometimes, the hard-talk of adults is not enough, but the words of their peers can always benefit them, because people of the same age understand their peers.

“Liberal arts are good, there are more girls, and when you get to college, there are more high-quality girls!”

“Science, good employment? In recent years, male preschool education has been very popular and popular!”

Several people were dumbfounded, and asked in a big way: “Xu Cong, have you studied? So we all choose liberal arts?”

Xu Cong didn’t have those thoughts, so he had to say to them: “Harm! Each has its pros and cons, it depends on how you weigh it! The most, most, and most important thing is that you have to go to university first!”

“I say that, you have an advantage in liberal arts, and you have to go to science to join in the fun, why bother?”

“Originally, you could go to a good school with your liberal arts scores. When you chose science, the gains outweighed the losses, and the exams were even worse. You couldn’t even go to university. What kind of job and employment would you talk about?”

“On the contrary, it’s the same! You are obviously very good at calculating, so you can learn by rote every day, is it possible?”

Several people also smiled, which makes sense.

“We all understand the great principles! But it’s not as intuitive as you said!”

“Yes! Xu Cong…”

“Xu Cong? Hello? This guy, is there anymore?”

“Fell asleep?”

“Damn! I want to say more! He fell asleep?”

“This guy!”.

…

Everyone had no choice but to stop the topic, so they had to sleep, “Forget it, that’s it! I’ll talk about it tomorrow.”

Xu Cong slept deliberately. If he kept talking like this, he would have no results all night, and he would not give his roommates a clear choice. No one can decide what their own future will be.

Their future is in their own hands! The path you choose is your responsibility! Lin Mengjiao is also very entangled, so she decided to call her parents tomorrow morning.

After dawn, Lin Mengjiao still washed as usual, went to buy breakfast, waited for Xu Cong, after breakfast, Lin Mengjiao used Xu Cong’s mobile phone to make a call.

After the call was connected, Lin Mengjiao said straightforwardly: “Mom! I want to ask, the school teacher has notified me about my course selection. After the monthly exam, I will be divided into classes. I want to ask your opinion.”

“Our opinion?”

Lin Mengjiao, “Yes.”

“What opinion can we have, ask Xu Cong! What he says is what he says! You listen to Xu Cong!”

Lin Mengjiao was a little speechless, so why did he get involved again, “Ah? No, Mom! Isn’t this supposed to be your suggestion? You, you?”

“Don’t bother! Just listen to Xu Cong! Xu Cong is no one else! Good! Hang up! Three!”

The other party was playing mahjong, Lin Mengjiao seemed to hear Zhou Xiuyun’s voice beside her, and she couldn’t help but guess: “My mother and Aunt Zhou are playing mahjong?”

Handing the phone to Xu Cong, Lin Mengjiao said to him with a sad look: “My mother asked me to ask you and let you decide.”

Upon seeing this, Xu Cong had no choice but to ask: “Do you personally prefer liberal arts or science?”

Lin Mengjiao looked at Xu Cong with a dazed expression, “I am under a lot of pressure, and I don’t want to be because I affected you.”

Xu Cong snorted: “That’s it?”

Lin Mengjiao: “!!!”

“Seriously, okay, what do you mean by this?”

Xu Cong smiled faintly, and said indifferently: “I said that you, Nizi, have a lot of thoughts. I just want to ask, whether I choose liberal arts or science, is there any change?”

“I……”

Lin Mengjiao was stunned. It is true that Xu Cong is not partial to subjects. More importantly, one day he really has enough. He said that he would find a university to recommend. Isn’t it crowded by countless universities?

“I choose science, I want to choose science!”

“Then science.”

Xu Cong rubbed Lin Mengjiao’s head, Xiao Nizi was so cute.

….…

In the new week, there is a new physics class. Xu Cong also borrowed from the mathematics teacher’s method, letting students choose and do their own questions.

Of course, in each class, Xu Cong will take time to compare with his classmates. The comparison is the problem-solving ideas!

topic:

As shown in the figure, on a rough horizontal surface, there are two small balls with masses m₁ and m₂, connected by a light spring in the middle. The original length of the spring is L and the stiffness is k. The ball is on the ground. The friction factor between is u.

There is a horizontal pulling force F on a small ball with a mass of m₂, which makes the two small balls move together at a uniform acceleration. What is the distance between the two small balls at this time?

A.(m₂F)/[(m₁+m₂)k]

B.(m₁F)/[(m₁+m₂)k]

C.(m₁F)/[(m₁+m₂)k]+L

D.(m₂F)/[(m₁+m₂)k]+L

The one who came up to do this question was a representative of the whole class. untie:

Regarding the two balls as a whole, F-u(m₁+m₂)g=(m₁+m₂)a

Isolate m1, get by Niu Er: T-um₁g=m₁a

According to Hooke’s law: T=KAxx=△x+L

So the final answer is: {m₁F/[(m₁+m₂)k]}+L neatly written on the blackboard.

Xu Cong asked: “Are you sure that the representative you sent to write is the simplest and most accurate answer you think?”

Everyone answered him in unison: “Yes!”

Tang Yongxue and Miao Tiantian also nodded earnestly, and at the same time asked: “Xu Cong! Can you give a better idea for solving the problem?”

Xu Cong chuckled slightly and said to them, “Can you please remove it!”

“When you do this, you can’t do it in a few minutes during the exam! I will teach you a formula, an internal force formula.”

The whole class is dumbfounded, “???”

Xu Cong wrote it down on the blackboard mockingly, and the font in line is more beautiful!

The classmates stared at them, and they only felt that Xu Cong’s writing was better than the Chinese teacher’s handwriting.

“This word, looking at it is a kind of enjoyment!”

Xu Cong looked at them speechlessly, “Stop flattering! Look at the question, look at the formula!”

T=[m₁/(m₁+m₂)]F

Xu Cong pointed to the formula and said to them: “The elasticity can be calculated, and the elasticity is there. Adding L, the answer is ready to come.”

The complacency of everyone was still on their faces, and Xu Cong solved the problem.

“Five seconds, will it be done soon?”

Everyone opened their mouths wide, completely surprised, “Wait, Xu Cong, you, this is…”

The students just wanted to ask, Xu Cong continued, “If the time is still long, then I have a faster, special value method.”

All the classmates, “Return him?!!!”

Everyone got numb scalp, “Ma Dan! Xu Cong, we think you are not here to teach! You are here to show!”

Xu Cong ignored these people and said, “If m₁ is set to 0 and the mass of the ball is 0, the spring has no length, so L does not change, but if m₁ is 0, all of them are 0. Then, option Which one of the first can get 0?”

The crowd was confused.

Fuck!!!

It’s too ridiculous! ! !
