Xueba, I beg you to go and escort him quickly!

Qin Fangming, "Xu Heng, is what she said true?"

Yue Pingting was confident, "every sentence is true!"

Xu Heng had black lines on his face.

So far, I can only admit it.

"Ok!"

Loudly!

The class was instantly quiet, and a needle could be heard.

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

Not only that, he even said it was simple!

"Bragging is not a draft!"

Many people gnashed their teeth.

Especially the representative of the physics class, "Stunning!"

Qin Fangming was very patient, "If that's the case, come on! I'll give you another quiz!"

topic:

A cat by the table jerked the tablecloth out of the fish tank, and the fish tank didn't slide off the table.If the kinetic friction coefficients between the fish tank, the tablecloth, and the table are equal, then ()

A The direction of the friction force of the tablecloth on the fish tank is to the left

The sliding time of fish tank B 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 pulling force, the fish tank may slide out of the desktop.

Qin Fangming also drew 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!

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

Not to mention other students.

Many students frown inexplicably when they see this question.

"Headache! I feel uncomfortable looking at this question! It's too difficult! There's no way to do it! Xu Heng, aren't you very capable? Tell me about it!"

"I don't have any ideas at all! I don't believe it, I'm not as good as a scumbag!"

"The physics teacher made things difficult for us on purpose!"

"It's not embarrassing you, but embarrassing Xu Heng!"

"If he, Xu Heng, can answer it, I'll go to the bathroom on my head!"

Many people turned their attention to Xu Heng.

Qin Fangming looked forward to it.

Xu Heng, "BD."

Qin Fangming's heart trembled, "What about the process?"

Xu Heng, "When the cylinder moves to the right, the friction force of the cloth on the cylinder will move to the right, so A is wrong, and the sliding friction has nothing to do with the pulling force, so C is also wrong."

All the students listened carefully.

But Xu Heng didn't say anything.

Everyone, "?"

Xu Heng, "It's over."

Everyone was shocked and blurted out, "It's that simple? It's gone?"

This is asking rhetorically!

But Xu Yi's answer was, "It's that simple, it's gone."

After a while, the students came back to their senses.

"This is a multiple-choice question, AC is excluded, and the rest can only be BD! This..."

"Teacher, is his answer correct?"

Qin Fangming's eyes were about to pop out.

"One more question!"

"The rotation of the earth is gradually slowing down. 3 million years ago, the rotation period of the earth was about 22 hours. Assuming this trend will continue and other conditions of the balloon remain unchanged, the geosynchronous satellites launched by humans in the future will be compared with the present..."

The teacher has not had time to say options.

Xu Heng said directly: "The height from the earth becomes larger."

This question is tested for high-orbit, low-speed, large-period, and low-orbit, high-speed, small-period.

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

"The topic is very simple!"

But Xu Heng's answer was also very rude!

Qin Fangming was speechless, as if Newton had discovered gravity, he was extremely excited!

Is this question easy?

"Come again!"

"There is an electric field distributed along the X-axis in space, and the diagram of its electric field intensity E varying with X is as follows. What the following statement strives for is:

AO point has the lowest potential

B. Point X2 has the highest potential

C. The potentials of the two points X1 and -X1 are equal

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

As he spoke, Qin Fangming began to draw pictures.

This was the single-choice finale question of the college entrance examination back then, and he still didn't believe it, this Xu Heng could be so evil.

You must know that to do this question, it will take a lot of time just to answer it, not to mention drawing pictures, but also to make various assumptions.

Very strenuous!

But when he was drawing the picture, Xu Heng said, "Choose C."

Qin Fangming's picture is not finished yet.

Click!

His chalk broke, and he turned around slowly, staring at Xu Heng.

It was very quiet in the class.

There are various question marks in the minds of the students.

Did you get it right?

next second!

Qin Fangming said, "I'll give you the chalk, you come to the stage to speak!".

Chapter 3

Xu Heng waved his hand, "No need! This question is also very simple."

"According to: the electric potential depends on the direction, and the direction depends on the positive and negative. This problem can be easily solved."

Direction refers to the direction of the electric field lines along which the electric potential is decreasing.

As soon as these words came out, Qin Fangming turned his head to look at the blackboard and finished his drawing.

Following Xu Heng's method, he began to gesture seriously.

"Fuck!"

In front of the whole class, Qin Fangming finally couldn't bear it anymore.

He was so shocked that he didn't know what words to describe his inner thoughts.

Only "fuck"!

"Where did you get this formula?"

"Electric potential depends on direction, and direction depends on positive and negative!"

"If you have this mantra during the college entrance examination, you can save three to five minutes of time! My God! You are a genius!"

"A top student! An absolute top student!"

"If you don't make a song, you're done! A blockbuster!"

"Self-study, everyone! Xu Heng, come out with me!"

Xu Heng, "Teacher, where are you going?"

Qin Fangming was excited, "Look for your homeroom teacher! You are the most amazing student I have taught for so many years!"

"Tell me, how do you usually study physics?"

Xu Heng, "Eh... Teacher, you know very well what I do in your class."

sleep!

Xu Heng always slept on his stomach in his class.

Qin Fangming, "So, you all went home and taught yourself! And you even learned super-class!"

"Tell the truth to the teacher! Do you think that what I said was too simple, so you deliberately slept in class?"

Xu Heng, "No, teacher, I am..."

Qin Fangming interrupted Xu Heng, "I understand! I understand everything! Hiss! My God! I actually brought out a super student!"

"Our Yunshan High School has hope!"

"Let's go!"

Came to Xu Heng's class teacher Yao Ruiyi's office.

She teaches Chinese.

young!

beautiful!

Responsible!

"Boom boom boom!"

"Teacher Yao! I'm Qin Fangming!"

A clear and pleasant voice came from the office, "Please come in."

Qin Fangming brought Xu Heng in, and Yao Ruiyi was taken aback, "Mr. Qin! Did Xu Heng mess up your class!"

"Xu Heng! What's going on? You..."

Qin Fangming immediately stood in front of Xu Heng, "Teacher Yao! Please don't get excited! Let me tell you something! Please be mentally prepared."

Holding the teacup, Yao Ruiyi stood up abruptly, her perfect figure was unobstructed.

Shirts, narrow skirts, stockings, high heels...

She looked at Qin Fangming suspiciously, "Mr. Qin, if I remember correctly, you should be teaching physics to my classmates at this time! What are you doing?"

Qin Fangming pulled Xu Heng, "Mr. Yao! Xu Heng in your class is the first one I have met after teaching for so many years. The legendary super student in other classes!"

Super academic?
