When the exam results came out, even though everyone was prepared, they were still shocked by Li An's results. 150 points, full marks. There was no such thing as a physics score exceeding the mark. If there was, it definitely wouldn't be Li An.
However, Li An was a little helpless. He had gotten full marks, but he didn't even have anyone to share it with. He felt very uncomfortable.
"At this moment, I want to share my full score.”
Yang Ning patted Li An's shoulder and said,""No, don't think too much. No one will share your physics results. Many of those people have left us.”
A few students looked at their results silently. The physics evaluation score for this exam was 75 points, which could be said to be the lowest score in history. When the statistics were finally released, everyone realized that the reason for such a low score was completely because the results of the other students in Li An's examination room were pitifully low.
Could it be the Wisdom Subduing Halo?
How could this be? Was this guy a demon?
The young man from Suhang Second High School saw Li An again, and his eyes wandered.
"It's okay. If you want to praise me, then praise me. I like compliments from others.”
The young man roared," No, this is my last pride in physics. I won't bow down. Also, you've already been guaranteed entry. Why are you still fighting with us for the spot? Aren't you not giving us a chance?”
What did he mean by not giving her a chance?
" It's fine," Li An said calmly." There's still the semi-finals the next day. You have to be prepared. The papers on the second day will be even more difficult."”
"You…are there any questions that aren't difficult?”
On the second day, everyone arrived at the examination hall early. Many of them were nervous. Compared to the first day, there were fewer people. At least half of the students were eliminated on the first exam.
The young man from Suhang Second High School opened the paper. It was a new paper, and it even had a hint of printing. Damn it, it was still warm.
"Three questions. What are they all about?"
"What the f * ck is this?"
Not only were the youths from Suhang Second High School stunned, but even the other students were also shocked. Wasn't this a joke? Was this an international joke?
There were three questions, and one question was worth 40 points. The full score was 120 points. Was the teacher angry? He directly used the hard stuff.
"I…I want to die. You can't even guess. You have to know that I'm possessed by Ou Huang.”
Li An silently picked up the paper. As expected, what should have come would have come.
What shouldn't have come still came.
At that moment, the thing that the physics students were most afraid of appeared. It was the legendary physics and chemistry question.
Physics students were afraid of this thing, and chemistry students were also afraid of this thing. In short, this thing was simply explained.
Physics wasn't physics, and chemistry wasn't chemistry. They were completely different.
"So, what the hell is this periodic table? Do you still need to memorize this?"
"Quark, is Quark out? When did Madame Curie and Newton have an affair? They were hundreds of years apart.》”
" Or is it that the final choice is practical?"
Li An pondered silently. This was the first time he tried to take an exam. He held a calculation paper in his hand and didn't know how to write.
"The theory of relativity, damn it. It's the general theory of relativity, Einstein's stuff. Is he planning to study nuclear weapons?”
Li An wrote silently. Soon, the answer became clearer. Forty points, easily obtained.
The second question was the same as the previous one. As expected, when a teacher set a question, there was a passive bonus. The difference between physics and mathematics was that physics had a wide range of branches. In other words, when a teacher set a question, they would choose based on what they knew.
There was only one choice for a teacher, and that was a specialized subject. The inevitable result would be to set a question purely for a particular subject in physics.
However, when he saw the last question, Li An was completely at a loss.
F * ck, this was considered a physics question?
The induction cooker uses a high-frequency current to generate a magnetic field in the coil inside the induction cooker to magnetize the bottom of the iron pot, forming countless small vortices to accelerate the movement of the molecules at the bottom of the pot. The bottom of the pot itself is heated at a high speed to achieve the purpose of heating food. Its working principle is shown in Figure 1.
The picture was given. It was just the structure diagram of the pressure cooker. The main point was that the structure diagram of the pressure cooker was the content of the basic user manual of the pressure cooker. There was nothing new about it.
Where was the highlight?
There were really some highlights.
The first question.
The induction cooker controlled by a micro-computer does not produce an open flame when heating, has no smoke, no exhaust gas, is clean, safe, efficient and energy-saving, and is the ideal stove in modern families. Please write down the physics knowledge that the induction cooker touches.
The second problem was that when using the induction cooker to heat food, the process between the induction cooker and the pot would consume--If it takes 25 minutes to steam 8 steamed buns with the induction cooker, how much time does it take to steam one steamed bun?
The third question: The performance parameters of a certain model of AJHEI induction cooker are shown in Table 1.

If the induction cooker was within the range of power adjustment and temperature adjustment, the change of heating temperature with power adjustment was exactly a straight line. Under normal circumstances, how many minutes would it take to boil a pot of 3kg 22 ° C water?
Tell me the truth, how much did Bai Fei give you? I'll give you three times the amount.
However, in Li An's eyes, the second and third questions could be calculated. However, the first question was an open question. Was this challenging his dignity?
Even a fool could write the name. It would be done by memorizing it. There would always be a use.
But who was Li An? A top student, a super top student. How could he just write his name?
The magnetic effect of electric current, magnetic field, magnetism, magnetic induction line, electromagnetic induction, energy conversion, molecular thermal motion, heat transfer, internal energy, molecular current, induced electromotive force, self-induction, vortex…
"Not enough. Just this isn't enough. There's more, definitely more. Hahaha, I want to become a supreme god. I want to defy the heavens. I want to kill five times.
