For a moment, there was fierce applause in the classroom.
This applause is enough to show that everyone is really convinced.
Yun Sangyu was somewhat relieved about this.
But I didn't waste so much saliva in vain.
However, just because some people understand it, doesn’t mean that everyone can understand it!
For example, classmate Du Fei.
"Sang Yu, what do you mean? This is your formula."
Ahem.
It can only be said that a scumbag is a scumbag, and it is a dimensionality-reduction attack against top academics.
Fortunately, Yun Sangyu is very patient:
"The formula used is very simple. It is the radius expression of the centripetal force provided by Lorentz force, and then substituting two different radii into it, the first small question of this problem can be solved.
Once you have the foundation for the first question, you will often have inspiration and breakthrough points for the second question. At least you should have a clearer image of the particle motion."
After talking a lot, Du Fei finally seemed to understand.
Even if you don't understand, you can't show it. Isn't that stupider than a pig?
Fortunately, the school bell rang at the right time.
All the students who came around could only go back to their seats first, and Yun Sangyu's ears were completely clear.
Time is like a white horse, passing by in the blink of an eye.
There is still one week left until the college entrance examination.
It can be said that all the senior high school students in the school were extremely nervous. A few students even went to the hospital for infusion because of nervousness.
Yun Sangyu is probably the only one who is calm and composed. She punches in the canteen on time for three meals a day, then goes to class, and practices in the evening. She is not mentally exhausted at all, but is very energetic.
Even classmate Du Fei is in trouble. He doesn't get enough sleep every day, doesn't eat well, and has dark circles under his eyes like those of a panda.
Every time I go to the cafeteria to eat, I always have books in my hands and never leave my papers.
From time to time, I even sigh, such as now:
"Sang Yu, why are you not in a hurry?"
Yun Sangyu was drinking water with a cup in her hand:
"If being anxious is useful, wouldn't it be better if everyone was anxious?"
That's what it says, yes.
"Sang Yu, don't you know how much pressure we, the poor students, are under?
Hey, yes, in the last mock test a few days ago, your score was better than Qin Ruiheng's, and now you have the highest score in our class. How can a top student know how we feel like a bad student?"
As he spoke, he sighed again.
If anyone knew that Yun Sangyu had finished learning all the subjects in just over half a month, and had mastered the essence of each subject, surpassing the top spot in the class for three years, who would be shocked?
How about that?
This is simply an existence that defies heaven!
Still human?
Ahem.
"Don't worry, tell me if you don't understand anything."
As soon as Yun Sangyu said these words, Du Fei's eyes suddenly lit up:
"real?
Wow, I know you are the best to me, Sang Yu!"
Probably, this is what I was waiting for.
What else can Yun Sangyu say?
When Duffy brought the question over, of course he explained it carefully.
‘Ring ring ring~’
The last class in the afternoon finally ended.
Yun Sangyu just finished explaining.
"Let's go and eat."
Du Fei weakly replied:
"I won't go. I'll do my homework and go back to the dormitory to eat instant noodles in the evening."
Yun Sangyu disagreed from the bottom of her heart:
"If you look like this, your body will collapse before the exam starts."
Well.
Classmate Du Fei was confused:
"Then shall I go?"
Yun Sangyu started to laugh:
"You can eat well only when you go, and you can continue studying only when you are full, right?"
