My Identity As A Schoolmaster Has Been Exposed

Chapter 2 Here is the chalk, you come to the stage to speak!

brush!

Everyone in the class turned their heads to look at Sun Yujiao and Xu Cong.

“Ha ha ha ha……”

“Aftermath!”

I don’t know which classmate said this, and then the whole class burst into laughter.

Even Lin Fang on the podium couldn’t help it, “Ha…cough! Classmates don’t laugh! Pay attention to class discipline, just keep it up!”

“Student Sun, do you know what you were talking about?”

Sun Yujiao nodded and said seriously: “I know! When I was discussing with Xu Cong just now, he even criticized him for talking about being an Antarctic bear.”

She spoke very clearly every word, and there was no falsehood in her beautiful eyes.

Lin Fang glanced at Sun Yujiao, then turned his eyes to Xu Cong, and asked in an incredible tone: “Xu Cong! Do you really know this question? Have you seen the same question type before?”

Xu Cong had already stood up at this time, ready to follow the teacher’s will to make big things small and small things into small things.

But Sun Yujiao took the lead. She quickly said: “Xu Cong also said, this question is so simple, what’s the fuss about him making it!”

Wow!

The whole class was in an uproar.

They looked at Xu Cong and Sun Yujiao’s eyes, as if they were looking at a monkey.

It’s enough to blow a little cowhide, it’s not funny if it’s too much!

Lin Fang frowned slightly, he still knew something about Sun Yujiao and Xu Cong.

These two have poor grades and are not good, but they still have some character.

Although Sun Yujiao was a little confused in her mind, she was not stupid, and lying did not benefit her at all.

Lin Fang looked at Xu Cong again and asked seriously: “Xu Cong, what she said is true?”

Before Xu Cong could speak, Sun Yujiao replied confidently: “What I said is true!”

Xu Cong had a black line on his face, and he was speechless. Now, he can only admit it.

“Um!”

His answer is loud and loud!

The whole class was instantly quiet, and the needle drop could be heard.

A scumbag actually solved the problem that caused headaches for all the students in the class.

Not only that, he even said that this question is simple!

“You brag and don’t write drafts!”

Many people gritted their teeth and looked at the two of them, especially the physics class representative, who said with a disdain: “To make a silly look!”

Lin Fang was very patient. Seeing Xu Cong’s admission, he wanted to see the level of the poor student before, and said, “In that case, come! I will test you with another question!”

topic:

A cat suddenly pulled the tablecloth out of the fish tank by the table, but the fish tank did not slide out of the tabletop in the end. If the dynamic friction factors between the fish tank, the tablecloth and the table top are all equal, then ()

A. The direction of friction between the tablecloth and the fish tank is to the left

B. The sliding time of the fish tank on the tablecloth is equal to that on the table

C. If the cat increases the pulling force, the friction force received by the fish tank will increase

D. If the cat reduces the tension, the fish tank may slide out of the table.

After Lin Fang quickly typed the problem on the computer, in order to reduce the difficulty, he added a sketch on the blackboard: the kitten is pulling the tablecloth at the corner of the table, and there is a fish tank on the tablecloth.

This is a multiple choice question in physics!

So if you are a little careless, even the students with the best grades will make mistakes because of ambiguity, let alone other students.

Many students started to think when they saw this question, but their faces were full of frowning expressions.

“Headache! This question is uncomfortable to me! It is too difficult! There is no way to start! Xu Cong, aren’t you very capable? Tell me about it!”

“No idea at all! I don’t believe it, I’m not as good as a scumbag!”

“The physics teacher deliberately embarrass us!”

“You are wrong, the teacher is not embarrassing you, but embarrassing Xu Cong!”

“If Xu Cong can answer it, I will go to the bathroom upside down!”

No one recognized Xu Cong, they even made a gambling contract with him as a joke, and then everyone looked at Xu Cong.

Lin Fang on the podium is also looking forward to it. After all, being able to change a student with knowledge is also a sense of accomplishment.

Xu Cong looked up and quickly gave the answer: “BD.”

Hearing Xu Cong giving the correct answer so quickly, Lin Fang’s heart trembled. To prove that he was not blind, he asked, “What about the process?”

Xu Cong faintly replied: “When the cylinder moves to the right, the friction force of the cloth on the cylinder is to the right, so A is wrong, and then the sliding friction has nothing to do with the pulling force, so C is also wrong.”

All the students put their ears up and listened carefully to his problem-making process.

But at this time Xu Cong stopped, he didn’t say anything.

Everyone, “?”

Xu Cong looked at their dull eyes and chuckled softly: “It’s over.”

Everyone was shocked and blurted out, “This question is that simple? Nothing?”

This is a rhetorical question!

Xu Cong still replied softly, “Yes, it’s that simple, so it’s done.”

After a while, the students recovered.

“Yes, this is a multiple choice question. He excluded AC, and the rest can only be BD! This…”

“Teacher, is his answer correct?”

At this time, Lin Fang’s eyes were about to stare out, this old school scumbag really became a god?

He did not answer the other students’ questions, and continued to say to Xu Cong, “One more question!”

“The earth’s rotation is gradually slowing down. The period of the earth’s rotation 300 million years ago was about 22 hours. Assuming that this trend will continue and the other conditions of the balloon remain unchanged, the future geosynchronous satellites launched by humans will be compared with the present…”

Before Lin Fang even had time to say the option, Xu Cong directly replied: “The height from the earth has increased.”

This question is tested with high orbit low speed and large cycle, low orbit high speed and small cycle.

The speed here refers to the linear velocity, angular velocity, and acceleration. The changes of these three will increase when increasing, and decrease when decreasing, so the answer is obvious.

“This question is very simple!” Xu Cong’s answer is simple, rude and powerful!

Lin Fang was stunned. At this moment, he seemed to be extremely excited when he saw Newton discover gravity!

Damn, this question is simple?

“Come again!”

“There is an electric field distributed along the X-axis in a space, and the electric field intensity E varies with X as follows. The following statement is striving for:

A. O point has the lowest potential

B. Point X2 has the highest potential

C. The potentials of X1 and -X1 are equal

D. The potentials of the two points X1 and X3 are equal”

With that, Lin Fang began to draw pictures on the blackboard again.

This was the single-choice finale of the college entrance examination that year. He still didn’t believe it. Xu Cong could be so evil.

You must know that when he did this question, it would take a lot of time to solve it, not to mention the drawing, but also various assumptions.

Very strenuous!

But while he was drawing the picture, Xu Cong spoke again: “Choose C for this question.”

Before Lin Fangtu finished drawing, his hands were still hanging in the air.

Click!

His chalk broke, he slowly turned around and stared at Xu Cong.

At this time, the class is extremely quiet, and the students’ minds are full of various question marks.

Did Xu Cong get the correct answer?

Next second!

What made them even more dumbfounded happened!

Lin Fang took a deep look at Xu Cong and said, “Here is the chalk, you come on stage to speak!”
