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

But everyone just stood there, staring at Xu Heng, without saying a word.

Just like that, ten seconds passed.

Xu Heng, "???"

Sun Jianhua remembered and asked, "Is there any more?"

Xu Heng, "It's gone, it's gone a long time ago."

Only then did everyone realize that Xu Heng had finished speaking.

Everyone smiled awkwardly, their faces were ugly.

Because of the influence of the previous few times, they didn't dare to decide whether Xu Heng had finished speaking.

In other words, Xu Heng's words were so good and his analysis was so thorough that they didn't want him to stop at all.

After clearing up his mood for a few seconds, Teacher Li was the first to stand up and applauded.

"Crash..."

"I am convinced! I am convinced from the bottom of my heart! Student Xu Heng, I am really convinced!"

Xu Heng also smiled, "Mr. Li, you are sincere."

Honesty?

and many more……

Student Xu Heng, you seem to have misunderstood something.

but……

PS: Thank you [tail number 6294] for your support!

Kneel for all support!Fifth update!Another day of more than 2 words!Four.

Chapter 282

"Crash..."

As Mr. Li's applause sounded, other teachers also applauded.

"Crash! Crash..."

There was thunderous applause.

Xu Heng disagreed.

Why did he say that the teacher here is sincere? !

Because you all set me up, why are you still pretending to ask questions on the spot, do you think I will believe it?

Teacher Li felt something was wrong and was very embarrassed.

He gasped, "Student Xu Heng! We, this, this... but..."

He couldn't speak again!

The words came to his lips, but they were still swallowed by him.

Because, these are the questions they really want to ask!

In the prior discussion, there was no such link!

This was added temporarily by the director!

In other words, it was a sudden whim and a temporary change of mind.

But Xu Heng looked at Teacher Li.

play!

Act on!

Fudge!

Then flick!

Harmful!

I've already exposed you, what are you doing?

Amid the applause, a physics problem came out.

A female teacher breathed a sigh of relief and handed over the physics problem.

It's been half an hour!

The second teacher's topic came out.

topic:

Each person received three closed boxes with two jacks on each box.

To determine what is inside the box and measure its characteristics without opening the box.

The available devices are: AC power supply and DC power supply at a frequency of 50 cycles.

puff-

Xu Heng almost burst out laughing.

He really can't laugh or cry.

Half an hour!

Half an hour!

Just hold back such a question?

"Teacher, are you sure? Just this one question? Are you sure you don't want to look in your own question bank, find a calculation question or something?"

Xu Heng's attitude perfectly interprets "That's it?"!

Anyway, you came prepared!

"Also, teacher, you made a mistake in this question, do you know? You have fewer devices, at least you need AC and DC instruments with known internal resistance and accuracy."

After pointing out the teacher's mistake immediately, Xu Heng continued talking.

"There is no voltage measured in either pair of jacks, therefore, no power supply is included in the box."

"Measurement of resistance with AC and then DC, one box gave the same result. Conclusion: the box contained a simple resistor whose value was determined by measurement."

"The other box has a great resistance to direct current, but is a conductor to alternating current. Conclusion: This box contains a resistor whose capacitance is..."

"The third box is a conductor for both AC and DC, and AC is more resistant. Conclusion: This box contains a resistor and an inductor, connected in series. The values ​​of resistance and inductance can be calculated from measurements."

direct!

simple!

Xu Heng didn't hesitate at all!

Even after reading the question, the answer is given in the next second.

It's as simple as seeing one plus one, and he knows it's directly equal to two.

But this group of teachers has never seen such an answer!

Even the most gifted students they have taught can't just give the answer after reading the questions!

Some teachers doubted, "I even felt that he didn't even finish reading the questions, so he gave the answer directly!"

Teachers, "%￥#@#￥..."

The female teacher, "!!!"

She sank and sat back on the seat.

At this time, her eyes were straightened, as if walking dead, "How is it possible! How is this possible... You not only pointed out the mistakes in my question, but also gave the answer directly!"

"Wait! This is a question I racked my brains to come up with!"

She was completely dumbfounded!

"I chose this type of question just because I was afraid that numbers would appear and it would be difficult to calculate when I was writing a question, so as not to make mistakes. But, but..."

But I never expected that Xu Heng solved it in a second, and pointed out her mistake in this question!

She stared at Xu Heng, looking at Xu Heng's indifferent expression.

She knew very well that it was Xu Heng who thought this question was easy!

Do not!

It is very simple!

It's surprisingly simple!

The female teacher's eyes twitched fiercely.

Xu Heng sighed resentfully, "Hey..."

Teachers, your acting skills are indeed very good, but... can your questions be a little level!

Have a snack!

Please!

Are you releasing water on purpose? !

Xu Heng, "???"

The female teacher looked at Xu Heng with helpless eyes, and almost wanted to vomit blood.

"Student Xu Heng, half an hour is my best effort!"

The teachers also looked at Xu Heng, and then at the female teacher.

They were all muttering, "Is the topic too simple?"

Xu Heng also nodded in agreement.

The female teacher was desperate, and her face was pale.

Xu Heng!

Be yourself!

"Teachers, I admit that I spent a little less time on this question, and I have a little food..."

"But the level of this question is not low at all!"

"It's just that Xu Heng thinks it's simple!"

"You can let the other physics group teachers take a look, and our physics group leader can also take a look! Let them evaluate and evaluate!"

Swish swish!

All eyes turned to the physics group.

These physics teachers were all ashamed, and the group leader was even more helpless.

"Ahem! This question, so to speak, is more difficult than the college entrance examination questions... It can be used in the International Olympic Physics Competition!"

As soon as the words came out.

clap la la...

Rumbling--

Only then did everyone realize that it wasn't that it was not difficult, but that Xu Heng was too perverted!

Fuck Fuck Fuck Fuck Fuck Fuck Fuck...

Some teachers have all these two words in their minds.

I was completely shocked, and my limbs were all stiff.

His eyes just stared at Xu Heng.

But Xu Heng still had a look of helplessness and disbelief, "Don't brag about you! Can this problem be put in the physics competition?"
