" Therefore, for the eggshell of egg number 2, the eggshell is subjected to two forces, one to the left and one to the right. In the end, a portion of the force is offset, and the remaining force is small, so..."
Xu Heng paused.
The students began to talk at once.
"That's why number 1 is easy to break! The one that is still is easy to break!"
Xu Heng replied," You're right!"
The students nodded and began to digest the question.
However, just when everyone had no doubts, Yao Ruiyi raised her hand.
Xu Heng said," Teacher, we don't have to raise our hands in class. If you have any questions, just stand up and ask directly.”
"Of course, the premise is that there are no other students asking questions!”
Yao Ruiyi said," This is good! I've learned it!"
She stood up slowly." I want to ask, when I'm frying eggs, the egg that moves goes bad first! Why?"
Yao Ruiyi's words came from her daily life and stunned the students.
They all looked sideways at Yao Ruiyi and then at Xu Heng.
"Hahaha! The form teacher is here to tear us down!"
Some students muttered.
Xu Heng was calm and collected." It depends on whether the eggs you use are parallel to each other! If one was high and the other was low, it would involve other forces!”
Yao Ruiyi sat down thoughtfully.
Xu Heng continued," Is this question OK? Then let's move on to the next question!"
"Let's turn the egg into three!"
"Do you know about the circus who throws small balls?”
"It's the performance where there are three of them. One of them is always in the air, and the other two are in the hands!”
"Let me tell you! This was a question for the college entrance examination, but it had also been tested in the middle school examination!”
"If you don't know how to do it, it's really embarrassing!”
As he spoke, Xu Heng wrote a question on the blackboard.
An actor was performing acrobatics. How much work did he do to an egg when he threw it?
A.300J
B.3J
C.0.3J
D.30J
Xu Heng asked," Choose what? Whoever chooses this question correctly will have to provide the basis. I won't talk about it anymore and will study by myself until the end of the class.”
"This question is very simple! Everyone, give it a try! I really can't go on! Let me rest!"
His class!
He had the final say!
This way, the students would also be convinced.
Self-study was better than class!
The students were all on steroids. At first glance, the questions were super simple.
However, once they started, especially when it was such a choice, they were ambiguous.
"First, eliminate A!"
"Agreed!"
"But what's next? 3？0.3？30？How?"
"This…I'm confused. I choose 3!”
"Yes! I also think 3 is very reliable!"
Yue Pingting frowned and thought for a while. She was not in a hurry to choose. She was looking for the formula. With the formula, she could calculate the result.
However, she had yet to find it.
As for the students with better grades, they began to work on the transformation of mechanical kinetic energy and gravitational potential energy.
Swoosh! Swoosh! Swoosh!
It was the sound of pen and paper.
Yao Ruiyi was also very interested in this question. She couldn't help but pick up a pen and paper to write and draw.
Xu Heng looked at the time and then at the crowd.
He sighed." Class is almost over! Everyone, I've told you! I'm a person who doesn't like to delay!"
"This question is very simple! You need to change your mindset a little.”
Everyone was speechless.
He felt that Xu Heng was looking down on him!
F * ck!
All of them were indignant.
But Xu Heng didn't give him a chance to retort. He said directly,"
"The work done by the human hand on the egg should obviously be converted into the kinetic energy of the egg. In the process of rising, the kinetic energy is converted into gravitational potential energy. When the egg reaches the top, the gravitational potential energy of the egg is equivalent to the work done by the hand on the egg.”
"The gravitational potential energy at the highest point is equal to mgh.”
"M, you have to pay attention to this. This is the mass of the egg. It's about 50 to 60 grams, which is 0.06 kg.”
"We usually calculate g in 10.”
"As for the height, from the navel to the mouth, it's about 0.5 meters. So I don't need to say anything more, right?”
Everyone was very reluctant and started to complain." So, we chose C.”
Xu Heng replied," Yes, that's why I chose C."
" Of course, when you are more knowledgeable and don't say 'I'm not well-educated, don't lie to me', you will know that the distance of force movement is very short, almost zero.”
Just as everyone was about to complain, Xu Heng's second method caught them off guard.
It was too sudden!
"Xu Heng, the next time you mention the second method, please remind us that we haven't had the time to change our minds!”
"That's right! It was very sudden! The key is that your second method is so simple. I didn't even have time to listen to it before it ended!”
Xu Heng waved his hand." There's no time. School is about to end!" It was time for dinner! If you don't say it, I'm going to drag the class!"
"I won't say anymore! The bell rang. Class dismissed! She went to the cafeteria!"
Xu Heng got up and wanted to run out.
After all, he was a useless person!
But thinking about it again, something wasn't right!
With his identity, was he considered half a teacher?
As a teacher, he was the first to rush out of class, faster than his classmates.
That's not good!
"Um…"
And Yao Ruiyi was still in class.
Alright then!
Xu Heng was back.
Yao Ruiyi stood up." Not bad. I don't think I need to come to the next class."”
"I'll give Teacher Qin a call and tell him to be at ease.”
Xu Heng nodded and went with Yue Pingting.
After dinner, the two of them strolled around.
Xu Heng asked," How's your leg?"
"Are you concerned about me?"”
Xu Heng smiled.
Yue Pingting said," By the way, I've received many love letters from my female classmates! It's all for you!"
Xu Heng shrugged. He didn't care about that.
"Year one, year two, year three, all of them.”
"Some people even asked me for your QQ or WeChat.”
"Yue Pingting, are you telling me that it's not too late to regret?"”
Yue Pingting immediately puffed up in anger. Xu Heng, look at what's in the bowl and eat what's in the pot! Err…No! He ate the food in the bowl and looked at the food in the pot!”
Xu Heng rolled his eyes." Then why are you telling me all this?”
Yue Pingting blushed." I, you, I…You're bullying me!”
Xu Heng looked at Yue Pingting coldly.
Yue Pingting replied," Uh…"
She glanced at Xu Heng.
The moment their eyes met, she was instantly terrified.
"I…I didn't mean that.”
"I just…I just want to drink milk tea!”
Xu Heng: "???"
Were all girls like this?
Do you really want to drink milk tea or are you pretending?
How could this matter be related to drinking milk tea?
Seeing Xu Heng's surprised expression, Yue Pingting almost punched her chest.
"You straight man!"
Xu Heng was speechless.
If you want to drink, then drink. Why are you so troublesome?
"You go. I'll wait for you. I'm not drinking.”
Yue Pingting was speechless.
"Then what's the point? I'm not drinking anymore. Let's go…"
She stomped her feet and returned to class in a huff.
Xu Heng was not used to it.
He went back.
It could be said that he was heartless.
Xu Heng returned to his seat and went to sleep.
Yue Pingting continued to be angry.
"Hah…"
It was not until the end of the evening self-study session that Xu Heng got up and stretched lazily.
Yue Pingting stared at him as if she was looking at her enemy.
After school, Yue Pingting left the teaching building and followed Xu Heng silently.
Xu Heng was speechless.
"Why are you following me instead of going back to the dormitory? I'm going to the boys 'dormitory. Are you coming with me?”
Yue Pingting said," I don't care…I'll follow you.”
Xu Heng said," Then tell me, why are you following me?”
Yue Pingting blushed. Humph!"
"Forget it! I won't lower myself to your level, but…I must get back the face I lost yesterday.”
The face he lost yesterday?
Today?
Did you lose face here yesterday?
Xu Heng was surprised.
Was there?
No?
Just as he was wondering, Yue Pingting grabbed Xu Heng's arm and ran to hide.
Avoiding the school's streetlights, the two of them came to a dark corner.
Xu Heng was puzzled and had yet to come back to his senses.
Yue Pingting came over.
Bam!
Damn it!
So this was what he was talking about!
Yue Pingting, I seriously suspect that you did it on purpose!
This girl was already so aggressive!
Could Xu Heng show weakness?
Hey! Girl, you're very unfamiliar. You can't!
You still want to regain your face?
Haha!
Let me teach you!
When the two of them sneakily came out from the corner.
Yue Pingting didn't even dare to raise her head.
Her entire body was red!
It was boiling hot!
Xu Heng smiled." I finally understand. I know why you threw a tantrum at me this afternoon. It's because you're jealous!”
Others wrote you so many love letters, and you don't care?
Shouldn't you clarify that you have a girlfriend?
That was probably what it meant.
But now Yue Pingting had thought it through. Her voice was as small as a mosquito, and she mumbled," I don't care anymore. Now, I've thought it through. She sent a love letter because you're outstanding. Besides, you chose me over so many people. I should be proud. I shouldn't let my imagination run wild..."
The relationship between Xu Heng and Yue Pingting was imperceptible.
It wasn't just one person. A few people even asked if it was because of their relationship.
Xu Heng knew this.
But he didn't know what Yue Pingting was thinking.
Feng Nianshang was the first one to do so, but now the principal had said so and even gave her a " gift."
Xu Heng kept saying that he wasn't, but he was waiting for Yue Pingting.
Was she willing?
Was he really ready?
Only when she was willing could Xu Heng be bold.
Yesterday!
It was an opportunity.
That was why they came and went, and Yue Pingting's " face recovery ".
After bringing him to the dormitory door, Yue Pingting rushed at Xu Heng fiercely. I will take revenge tomorrow!"
Xu Heng smiled.
This girl was so proactive that he couldn't wait to be happy!
Comfortable!
Back to the dormitory!
When Xu Heng arrived at the dormitory, there were many people standing at the entrance.
"Student Xu Heng is here!"
"Student Xu Heng! Sorry, I'm here again!"
It was Liu Yixiang. He came with Liu Yixiang, and there were also many third-year students.
Xu Heng said," Give me some free time! Everyone, I still want to sleep and play with my phone! You guys come here every day and ask me for ideas. It's useless even if my mouth is dry.”
"The master leads the way, but the cultivation depends on the individual!”
"If you want to open your mind, ask our classmates. They have experience!”
"These few in our dormitory will do!”
Liu Yixiang and the others were dumbfounded." This…?？？”
His roommates all knew that these people were the top students in Year Three.
Giving them a lecture, this satisfaction was overflowing!
His roommates even gave Xu Heng a certain look." Leave it to us. Don't worry and play with your phone!”
Xu Heng was lying on the bed, playing with his phone, looking very comfortable.
On the other hand, Liu Yixiang and the others were all frowning.
Some people had no choice but to turn around and leave.
There was also a third-year high school student with a buzz cut who said fiercely," Xu Heng, that's all you've got! It's just a false appearance! What kind of person is this!"
Xu Heng was wearing earphones, so he naturally didn't hear it. However, his roommates didn't agree.
"Are you crazy? Moral kidnapping?"
"If our Xu Heng is willing, then he is willing. If he is unwilling, then he is unwilling. Remember, you are here to beg! Why are you so arrogant?"
"What's the use of having good results? Learn to be a human first!"
"If we see you in our dormitory again, we'll beat you up!”
This person's expression froze." Are you afraid of you? Just you guys? I'm a senior and I'm afraid of you?"
Liu Yixiang's face immediately darkened. Although he was gentle, it was not easy to change his position.
"This isn't a problem of the second or third year!”
"Everyone, don't be angry!"
“……”
He tried his best to be a peacemaker.
He was the one who had brought these third-year students.
Now, he was digging his own grave.
Xu Heng stopped teaching.
What could he do?
Xu Heng had already done his best to give him a solution.
If they didn't appreciate it, then that was their problem.
The senior year students were shouting and even shouting about beating people up.
The dormitory was nearly 1.9 meters tall. He was tall and burly, and he came back from washing up.
"What's wrong?"
This third-year student said," What do you mean what's wrong? Look at how arrogant the people in that dormitory are! Xu Heng was amazing! I'll see if you can run away after school on Friday!”
He wanted to block people and beat them up!
This guy was threatening!
Xu Heng was in the dormitory, watching the drama attentively. He had no time to care about what was happening in the corridor outside.
His roommates were completely enraged.
"Close the door and don't disturb Xu Heng!”
They respected Xu Heng from the bottom of their hearts.
It was Xu Heng who let them have their fun explaining questions for the tyrants!
It was Xu Heng who gave them physical education classes!
It was Xu Heng who rekindled their love and desire for learning!
"If you're mocking us, then so be it! Xu Heng is not someone you can talk about!"
"Big chunk! Get him!"
This student who was nearly 1.9 meters tall came in front of this guy. Just the comparison of their bodies made the other party's legs tremble in fear.
One was nearly 1.9 meters tall!
One of them was only 1.7 meters tall and was thin!
This gap!
Completely crushed!
"What are you doing! What are you doing! Let me tell you, this is the dormitory! Go and call the warden! Hurry up and go!"
The third-year student panicked!
With such a ruckus.
There were many students watching in the corridor.
Many of the students laughed evilly at the same time.
"Is this guy's brain not working well? Call the dorm manager? He was not asking for trouble! Are you courting death?"
"Exactly! The warden is Big Dipper's uncle!"
……
He wrote more than 20,000 words a day, and his fingers were trembling!
His brain was swelling and buzzing!
Please support me! Everyone! Thank you! Kneel and thank him!
