Chapter 384: Go back door

This question is simpler, and Yue Feng replied: "This can also be explained by the above theory. Different materials, the corresponding material density must be different.
Those who have studied junior high school physics know that the buoyancy of an object in the water is equal to the gravity of the water.
Two objects of the same volume, regardless of their own weight, have the same buoyancy in the water, but the objects of different densities have different weights, and the remaining buoyancy after deducting their own weight will vary.
If you want to achieve the same amount of lead, the floating volume of different materials must be different. This returns to the old problem. The smaller the overall volume and the smaller the cross-sectional area, the more sensitive it is. There is no contradiction. "
After the theory was finished, the students in the audience began to shine. This explanation is easy to understand and directly analyzes to a very deep level. Many students who were still a little confused before realized the truth in an instant.
"It's a good talk, it seems that you have studied hard, and it's good, very good!"
Instructor Yang now looks at Yue Feng like a teacher looks at his proud student, the more he looks at the more pleasing to the eye, this guy has too broad a knowledge base.
"Hey, you praised it!!" Yue Feng grinned, feeling that today's pretense is complete again.
…
In the afternoon, there was only one big class. After the instructor asked questions, it later became an extended discussion time. The instructor summed up the next Yue Feng's speech, and a class passed unconsciously.
Near the end of the get out of class, the instructor reminded everyone that the basic theory is almost the same. Tomorrow, it will be assembled in a small square with equipment, and the actual practice of outdoor pole pool will be officially started!
There are some lecture plans, but I heard the instructor said that everyone is still more excited, and I can finally practice training.
After the class, the students dispersed.
Yue Feng was still the same, waiting for the door lock, Zhao Zheng and Ma Tingting were not in a hurry, but instead of taking advantage of the afternoon, they planned to add up with Yue Feng and make some more comments.
Here is waiting for Yue Feng in the corridor outside the door. Qin Hu walked out of the classroom in a half-snap shot. Instead of leaving with others, he walked towards Zhao Zheng.
"My elder brother, who are you waiting for?" Qin Hu said casually.
"Don't, the old saying in our hometown is that when brother is damn, you call my brother!" Zhao Zheng's impression of Qin Hu has been very poor after playing cards and playing routines twice. When he spoke, he unconsciously brought a little emotion .
"Well, this is mad at me? What are you doing inappropriately, buddies, let's make it clear to the face, tell things right, don't put guns and sticks!" Qin Hu simply pointed out the words.
Qin Hu is not a fool. Zhao Zheng has deliberately targeted him in class several times in a row. He deliberately came over late this time to talk, and his purpose was to explore Zhao Zheng’s tone.
Zhao Zheng's eyes said calmly: "Brother Hu thought more, nothing happened! My mouth is a bit broken, not intentionally directed at you!"
Zhao Zheng is now in a calm state. There are still some cities in this place. No matter how hard he sells, he does not show it on his face. As Yue Feng said, knowing that the character is not good, there is less contact and there is no need to turn around.
"Oh, then I'm relieved! When you leave, you can talk about something!" Qin Hu waved his hand and turned away.
When Qin Hu went away, Ma Tingting whispered: "You have a conflict with this guy? From the first time I saw him, he felt strange to me!"
Zhao Zheng pouted: "It's no big deal. This guy called me to play cards and played routines. It was seen by Brother Feng. I'll see him a little bit uncomfortable in the future. This guy is also elitist. He noticed signs, which was intentional. Come and find me to talk!"
"Oh, that's it, then don't disturb him less. With that kung fu research and research section, we can increase the number of fans!"
In a few words of kung fu, Yue Feng locked the door and came out, told Zhao Zhengting and the three of them, and walked towards the dorm upstairs.
Several pieces that challenged the entire network in succession have led Yue Feng and Ting Ting to grow their fans very quickly recently. Yue Feng is less than one thousand away from the 500,000 fan mark. Even if it grows naturally, it is estimated that there will be another Three or two days are almost the same.
The hooking challenge hasn't been filmed in this series anymore. If you want to make new content, you can only find a new way. However, the content of the lectures in the last one or two days is relatively basic. Although it also has teaching significance, it lacks topicality and attention. Yue Feng After discussing with Zhao Zhengting for three people, I gave this direction.
In Yue Feng's heart, Duanzi must have something to say, and then send quality products, or not to send, not to send a satin for the purpose of satin, the selection of materials and the intention of the sect can not pass their own level, there is no need to shoot.
"Otherwise, wait a moment. At present, we have room to increase the data of the three popular segments in the challenge series. I'm not in a hurry to update it later. Let me add up and look for a new creative point!" Yue Feng said.
Ma Tingting nodded: "Okay, let's go back and discuss any good ideas!"
"So what are we going to do next? Or else find a place to hang out? I don't know if there is a fun night show nearby, it's okay at night, let's go out together?" Zhao Zheng suggested.
"Okay, okay, that boy and girl's bar over the city is very good, or let's go there to play!" Ma Tingting said with great interest.
Yue Feng shook his head and said seriously: "Otherwise, you two will go to play. I will be fine with what to eat. If I am not interested in the night show, I will not give you a light bulb.
Besides, the instructor may have a ward round at night, anyway, he is also the squad leader. The instructor asked, and I said you two asked me for leave! "
Zhao Zheng pouted his mouth~EbookFREE.me~ Tucao said: "Cut, Brother Feng, you are good everywhere, but it is too stable. The young people will look like young people. Let's go, I invite you, tonight. Zhao Gongzi pays for all consumption!"
In the end, Yue Feng didn't go out to play. He had dinner in the honest canteen and played with his mobile phone in his room. During that period, he called the doll for a while and turned off the lights to sleep on time.
Zhao Zheng and Ma Tingting didn't return overnight, but they didn't see anyone when they got out of the exercise the next morning. Yue Feng made several consecutive calls and no one answered them. Both of them were unable to connect.
Despite being unable to get through, Yue Feng was not nervous. Last night, at least a little bit, Zhao Zheng sent WeChat to Yue Feng, his phone was out of power, and spent the night outside, letting Yue Feng help cover.
My brother and Zhao Zhe and Chen Chen must not have been treated the same way. When Chen Feng finished his morning exercise, he reported to the instructor in private.
The content is very simple, Zhao Zheng asked for leave to go out, but did not exercise in the morning. Ma Tingting's stomach is uncomfortable, and she went out to go to the clinic to hang Shui'er.
For the monitor, this little thing is not worth mentioning, but when the class was gathered in the morning of the next morning, Zhao Zhe and Chen Chen did not do it.
