Why couldn't it live peacefully on this piece of land or that piece of land?
Could it be that the female bird living on this piece of land was the one he had an affair with, and the other was his wife? Could it be that the female bird living on this piece of land was the one he had an affair with, and the other was his wife?
Nangong Nuannuan glanced at Nangong Jin. Seeing that he had finished reading the paper calmly, he flipped through the paper. After confirming that everything else was correct, he returned the paper to the principal without any expression on his face.
The teacher surnamed Zheng said, "Nan Xu's parent, you've read Nan Xu's paper. I'd like to hear your opinion."
Nangong Jin looked at Teacher Zheng with a strange expression on his face.
Teacher Zheng was a middle-aged woman in her forties, but she blushed under Nangong Jin's stare.
"Why, you have nothing to say, right? You also think that Nan Xu is wrong, right? If you really think so, I hope that you can go back and discipline Nan Xu. At least let him understand what it means to respect his teachers. "
Nangong Xu said lightly, "Teacher, from the argument between you and Nan Xu's form teacher just now, I can tell that you came up with this question, so you're very dissatisfied with Nan Xu's rejection of you. Nan Xu is still young, so he can't make an analysis based on scientific theories. He can only analyze the feasibility of crows drinking water and birds flying across the ocean. However, I can tell you a formula for buoyancy very clearly.
If you want a piece of wood to carry a bird, then you need to meet one condition, which is — the buoyancy produced by the wood — the gravity of the wood + the gravity of the bird.
In order to maximize the effect of the wood, we assume that the wood happens to be completely below the water's surface. Then, we can conclude that the density of water * volume of wood * acceleration of gravity * density of wood * volume of wood * acceleration of gravity + weight of bird * acceleration of gravity. Combining the similar items and simplifying them, we get: volume of wood * (density of water – density of wood – weight of bird).
The density of water is about 1,000 kilograms per cubic meter, and the density of wood is between 400 and 750 kilograms per cubic meter. We'll just assume that this bird is very smart and found a lighter type. The density of wood is 500 kilograms per cubic meter. We can conclude that the weight of bird/volume of wood is -500 kilograms per cubic meter.
Simply put, this is the conclusion: If the bird weighs one kilogram, then the volume of wood is -1/500 cubic meters, -0.002 cubic meters, -2 cubic decimeters.
Teacher, do you know what 2 cubic decimeters means? These are the bricks we usually see, about two. What was the concept of a bird weighing one kilogram? A chicken weighed about three to four kilograms. One kilogram was a small chick.
Could a bird the size of a chick carry two pieces of wood the size of a brick or a wooden stick as thick as an arm? Even if it was possible, the resistance of the wind on the wood would cause it to be swept directly from the surface of the sea to the bottom of the sea.
You might say that the bird in your proposition is big, much bigger than a chick. But the bird was big, and the weight was also heavy. When the time came, it might not have to carry a branch as thick as an arm, but as Nan Xu said, it would have to carry a pillar. I don't think a bird could carry a pole. Teacher, what do you think? "
Principal: "…"
The homeroom teacher, "…"
The teacher, "…!!!"
Nangong Nuannuan, on the other hand, looked very serious. But on the inside, she felt that she could laugh herself into internal injuries.
Her brother was probably a male chauvinist, right?
Appraisal complete!
Nangong Jin seemed to think that he had not angered the teacher enough.
