My Identity As A Schoolmaster Has Been Exposed

Chapter 141 The Physics Teacher Is Stunned

“Why, at the same table with Xu Cong, is it affected?”

Lin Mengjiao was taken aback, and said blankly: “I, I have improved? I have improved a lot? Teacher, are you talking about me?”

Su Rui said again: “Otherwise? Who am I talking about?”

Lin Mengjiao smiled, smiling brightly!

Wow!

Su Rui looked at Lin Mengjiao with emotion. Others are falling in love. These two are good, but they can still go up!

Hiss… It seems that other people’s grades have declined because of their lack of stability. Like Xu Cong, his grades are too stable.

Say that full score is full score!

“Okay, okay! If you want to see the specific results, you can go to my office to see it! Now let’s take a look at the Chinese test paper!”

The Chinese class is over, it’s physics class!

The physics teacher was sick for a month and finally came back. I didn’t expect Class 3 to give him such a gift.

Let’s not say Xu Cong’s full score. Two other students in the class got full scores! When the physics teacher Qin Fangming walked into the class, his eyes were a little stretched.

“I’m going! I’m going! I’m going to want to shed tears!”

“When I come, you will give me such a big meeting ceremony!”

“You little guys, it’s so awesome!”

The class was full of fun, and everyone said in unison, “This is all Xu Cong’s credit!”

When Qin Fangming came to Xu Cong, he did not walk, but trot, ran to Xu Cong and squatted down directly.

This shocked!

I’m almost kneeling on one knee!

Rumble… This was witnessed by all the students in the class.

“Teacher Xu! Thank you! I have worked hard for you during this time!” Xu Cong stunned.

Teacher Xu? ? ?

“Teacher, you are too much!”

Qin Fangming said to him: “No, no, no, I mean it! Really! What I said is true! It’s really hard for you! Teacher Xu, thank you!”

Looking at Qin Fangming, Xu Cong didn’t resist much. He just sighed and said, “It’s good if you are here!”

He could finally let go, Qin Fangming wiped his tears, this feeling made the little girl cry.

“Teacher, you are exaggerating!”

Qin Fangming raised his head and sighed: “It’s not an exaggeration! It’s not an exaggeration! You all got the first grade exam! Shouldn’t I be moved?”

“Okay, okay! Examination papers or something, I will go back today and read it again, and I will tell you after I understand it myself.”

“Let’s go to class first!”

“I haven’t been idle in the hospital during this time, so I patronized to prepare lessons for you!”

“Just save energy, wait for you to come back, give you a good lecture!”

“Classmates, open the textbook!”

Before he finished speaking, the classmates didn’t read the textbooks one by one, and no one took them. Qin Fangming was confused, with question marks all over his face.

“What’s the matter, what’s the matter with you?”

The physics class representative slowly stood up and said, “Ahem! Well, teacher, we have all learned the contents of this semester textbook, and your preparation for the lesson may be useless…”

“Poof Duh Ahem Ahem Ahem cough! Really, really fake? Finished school? Whole school finished? All right?”

Qin Fangming’s eyes widened, and he couldn’t believe what he heard. He glanced across the class, and everyone nodded seriously.

Finally looking at Xu Cong, Xu Cong shrugged helplessly, and said helplessly: “I didn’t stop the brakes by accident!”

Accidentally?

Did you finish telling me by accident?

scare!

Xu Cong, why don’t you go to heaven!

My goodness!

You have finished telling me, what am I talking about? I have been in for a month!

I wanted to come back to teach my classmates from the hospital bed!

Qin Fangming suddenly had no tears, and he was not moved at all. He wanted to cry without tears!

“Xu Cong, don’t take you like this! You are too fierce! You are too bullying! Hiss”

Qin Fangming had a headache, one head and two big heads.

Looking at all the students, and then at his own lesson preparation on the podium, he was so thick and thick, and he even prepared the corresponding supporting exercises carefully.

Suddenly he was full of confidence, and he felt like he was completely vented.

It looked like a swollen balloon with a hole in it. After a while, he buckled.

The smile on his face disappeared, and the person felt a few years old instantly, and the whole person was depressed.

“Teacher, teacher, are you okay?”

“Although Xu Cong has finished speaking, it doesn’t mean we don’t need you anymore! We still need you very much!”

Qin Fangming didn’t smile, but he quickly returned to normal.

“Ahem! Okay! I accept the reality, so do you have anything you don’t understand? It’s the content of the following course. Do you have any questions?”

No one shook his head, let alone said a word, Qin Fangming suddenly wanted to fall off the table.

What a mess!

The corners of his eyes twitched.

“The first few rows are okay. Don’t be embarrassed by the classmates behind you. If you don’t understand, you can ask?”

But no one cares about him, how?

Is it possible to lie?

Qin Fangming felt helpless, and for the first time he felt that he was not needed. He felt that he was abandoned.

“Hey… I really want to find a mouse hole to go in.” Qin Fangming slowed down for a while before he was relieved.

Although the course is over, but the course is still there. After finishing the course, let’s do the topic!

Qin Fangming began to write questions on the blackboard. He wanted to use the questions to conquer this group of students, so he began to say: “Let’s make a question!”

topic:

As shown in the figure, the writing surface of the isosceles triangle with the inclination angle a is fixed on the horizontal surface, and a light silk ribbon of sufficient length is placed across the top of the inclined surface on both sides of the upper, and there is no friction between the ribbon and the inclined surface.

Now put the small blocks with masses of M and m on the ribbons on both sides of the inclined plane at the same time.

The dynamic friction factor between the two blocks and the ribbon is equal, and the maximum static friction force is equal to the sliding friction force.

When angle a takes different values, which of the following statements are correct?

A. The magnitude of the friction on the two blocks is always the same

B. It is impossible for two objects to be stationary relative to the ribbon at the same time

C.M cannot slide relative to the ribbon

D.m cannot slide upwards relative to the slope

After writing this question, Qin Fangming felt alive again.

Yes, he is very confident in this question!

The answer to this question is very complicated, but he has the answer. Looking at the classmates, Qin Fangming smiled and said, “Classmates…”

He hadn’t finished speaking yet. After a while, a classmate stood up and said to him: “Teacher, this question is simple!”

Jane…simple?

Qin Fangming just wanted to say that it was difficult, but a classmate actually stood up and said it was easy?

Moreover, in his impression, the grades are still moderate, not very good ones.

???

Qin Fangming said directly to him: “Come here! For you, how do you do this question! Come on! Come on! Come on! Give you chalk!”

The classmate grinned, “Teacher, then I’ll really say it.” Qin Fangming had a black line after hearing it.

After reading this, the student said: “We assume that the friction coefficient u is infinite, and M and m are stuck on the silk. In this case, B is wrong!”

“If we say that the friction coefficient u is infinite, M slides down, and m slides up, so D is also wrong!”

“Teacher, sometimes you have multiple choices for this question, so you choose AC, right?

Qin Fangming was dumbfounded: “!!!”

Quiet!

The classroom is extremely quiet at this time!
