2384 The iron-like straight boss Nangong (1)

Why couldn’t it live peacefully on this or that land? Could it be that the female bird that lived on this side of the land was its wife on the other side?

Nangong Nuannuan glanced at Nangong Jin and saw that he had finished reading the paper calmly. After checking that he had gotten everything right, she returned the paper to the principal without any expression on her face.

Nan Xu’s parent, ” the teacher surnamed Zheng said, ” you’ve seen Nan Xu’s test paper. I’d like to hear your opinion.

Nangong Jin looked at this teacher Zheng with a strange expression.

Teacher Zheng was a middle-aged woman in her forties, but her face turned red from Nangong Jin’s stare.

“What, you don’t have anything to say, right? You also think that Nan Xu is wrong, right? If you really think so, I hope you can go back and discipline Nan Xu. At least let him understand what it means to respect his teacher.”

Nangong Xu said indifferently,”this teacher, from the argument between you and Nan Xu’s form teacher, I can tell that this question was set by you, so you’re very dissatisfied with Nan Xu’s rejection of you.” nan xu was still young and could not make an analysis from scientific theories. he could only analyze the feasibility of crows drinking water and birds flying over the ocean from a normal perspective. However, I can tell you a formula about buoyancy.

if you want a piece of wood to carry a bird, you have to meet one condition, which is-the buoyancy of the wood-the gravity of the wood itself + the gravity of the bird.

in order to maximize the use of the wood, let’s assume that the wood just happened to be completely under the water’s surface. then we can conclude that the density of water * the volume of wood * the acceleration of gravity-the density of wood * the volume of wood * the acceleration of gravity + the weight of the bird * the acceleration of gravity. After combining similar terms and simplifying them, the result was: Volume of wood *(water density-wood density-bird weight).

The density of water is about 1000 kilograms per cubic meter, and the density of wood is between 400 and 750 kilograms per cubic meter. We’ll take it that the bird is smart and found a lighter type. The density of wood will be calculated at 500 kilograms per cubic meter. It could be calculated that the weight of the bird/the volume of the wood-500 kg/cubic meter.

Simply put, this was the conclusion: If the bird weighed one kilogram, then the volume of the wood would be -1/500 cubic meters, 0.002 cubic meters, and 2 cubic decimeters.

Teacher, do you know what 2 cubic decimeters is? It’s the common bricks, about two pieces. What was the concept of a one-kilogram bird? A chicken weighed about three to four catties, and a one-kilograms-heavy chicken was a little chick.

Could a bird the size of a chick pick up two pieces of wood the size of a brick or a wooden stick the size of an arm? Even if it could, the wind’s resistance to the wood would cause it to be swept directly from the sea to the bottom of the sea.

one might say that the bird in your question was bigger than a chick-sized bird. However, the bird was big and heavy. When the time came, it might not be holding a branch as thick as an arm, but, as Nan Xu had said, a pillar. I don’t think a bird can lift a pillar. What do you think, teacher?”

The principal was speechless.

Form teacher:

The teacher who came up with the questions:

Nangong Nuannuan, on the other hand, looked very serious. But on the inside, she felt that laughing would hurt her.

Her brother was probably a straight man.

The appraisal was complete!

Nangong Jin seemed to think that he hadn’t said enough to anger that teacher to death, and said …
