v4 Chapter 849： A punch comparable to a nuclear bomb

"How much energy did the Angris meteorite produce when it hit the planet?" Eve was suddenly curious about the meteorite hitting the planet.

"This question..."

Liu pushed his glasses and analyzed: "This issue must be discussed separately. When a meteorite hits a planet, first it is kinetic energy, and then it may explode if it hits the ground.

"If you want to calculate the energy of the explosion, it is more troublesome, and the kinetic energy is relatively easy to calculate.

"Moreover, in fact, in terms of destructive power, the destructive power of kinetic energy in one direction is far higher than that of an explosion."

Someone asked doubtfully: "The power of an explosion is less than kinetic energy? Isn't it?"

After thinking for a moment, Liu explained: "Actually, in the impression of many people, there will be an illusion that subconsciously thinks that the explosion is terrible.

"But in fact, the destructive power of an explosion is actually very general compared to unidirectional kinetic energy.

"It's easy to understand to give an example, just take a bullet.

"The destructive power of a bullet after it exits the chamber comes from the gunpowder in the shell.

"So, if we pour out the gunpowder from the eggshell and make a firecracker, what do you think will be the power?"

This example is indeed very easy to understand. If the igniting powder in the cartridge case is made into a firecracker, it will explode directly in the hand and it will not be too powerful.

Liu went on to say: "This is easy to understand, right? Using a bullet of gunpowder as a firecracker, the most destructive power is the level of the skin.

"However, such a igniter, placed in a bullet, converts energy into kinetic energy when it explodes, and shoots the warhead out, but it can penetrate the hardest skull.

"From this, it can be seen that the destructive power of kinetic energy is stronger than that of an explosion.

"In fact, most of the destructive power of the explosion is also reflected in the shock wave. In fact, it is also the kinetic energy destructive power. It is just the spreading shock wave. The farther the range, the less damage it causes."

The comparison of the destructive power of firecrackers and bullets can indeed clearly distinguish the destructive power of kinetic energy and explosion.

Eve tapped his chin with his finger and thought thoughtfully: "So, kinetic energy is indeed more destructive. No wonder a ten-kilometer-diameter asteroid hit the earth and wiped out the dinosaurs."

Liu typed out a set of data in the notebook, then did some calculations, and said: "As for the energy of the Angliss meteorite hitting the beast planet...

"Let's calculate the kinetic energy of this meteorite's impact.

"Based on the exploration and analysis of the crater, we can probably draw a conclusion that the diameter of the Angris meteorite is about three to five kilometers...

"Combining the density of magnetite and part of the rock, we can calculate an approximate mass.

"For the convenience of calculation, we take an integer, the mass of the Angliss meteorite, 30 billion tons.

"Then the speed at which the meteorite fell.

"The falling speed of the Earth's meteorite is about 20 kilometers per second to 70 kilometers per second.

"From the degree of fragmentation of the meteorite fragments in the Angris crater, we can speculate that the impact velocity of this meteorite should be low.

"Therefore, we assume that the impact velocity of the Angris meteorite is 20 kilometers per second, and then calculate the kinetic energy during the impact.

"The final answer is 6×10^21 Joules.

"6 times 10 to the 21st power, which is 60 trillion gigajoules, which is 600,000 gigajoules in higher units."

When Fang Yuan heard this number, he couldn't help taking a deep breath.

600,000 Jing Joules, this is a terrifying order of magnitude.

Eve began to point her fingers: "The Captain's Dark Matter Dragon Punch can hit 115 trillion joules, so..."

She wanted to calculate the difference, and then found that the value was too large, and she couldn't figure it out all of a sudden.

Fang Yuan coughed quickly and said, "What, let's count the power of the little boy."

The actual values ​​are too different to compare.

After all, an asteroid with a diameter of five kilometers has a mass of 30 billion tons, and the mass of light is not comparable to that of humans.

However, if it were the nuclear bomb called the "little boy", it would be a bit comparable.

The nuclear bomb named "Little Boy" was dropped on an island in the last century, almost ending a war.

Chen Likun was particularly interested in this kind of data analysis, and quickly took over and said: "I remember the data of this nuclear bomb very clearly.

"The little boy is 15,000 equivalent, converted to joules, that is 63×10^12 joules, which is 63 trillion."

Fang Yuan was a little satisfied when he heard this value, with a smile on his face.

Eve began to point his finger again and calculate: "The 63 trillion joule boy, the power of the Captain's Dark Matter Dragon Fist is 115 trillion joules...

"Hey, it's the same. Captain, you can do it. You can hit two nuclear bombs in one punch."

From a numerical point of view, the power of Fang Yuan's punch is indeed equivalent to twice the energy produced by the "little boy" burst.

However, the problem of kinetic energy destructive power and explosive destructive power still exists.

Dark matter dragon fist is a unidirectional kinetic energy power, while a nuclear bomb explosion is a proliferation power in all directions.

The difference between the two can indeed be compared with firecrackers and bullets.

Therefore, from the point of view of destructive power alone, the 115 trillion joule of dark matter dragon fist at one point is far more destructive than the "little boy".

However, the destructive power coverage of Dark Matter Dragon Fist is relatively small.

Therefore, if used to deal with the tide of star beasts, nuclear bombs like the "little boy" are actually more effective, and the dark matter dragon fist is more suitable for killing high-level star beasts.

Fang Yuan said with a serious expression: "A punch that produces twice the power of a nuclear bomb is not enough. What do I say to the General Staff?"

The person in charge of the assessment team said blankly: "The'little boy' has been a fission bomb of the last century, with an equivalent of only 15,000 tons. Nowadays, the commonly used nuclear weapons are hydrogen bombs, most of which are above 500,000 tons. It's not enough for comparison."

Eve helped to argue: "That's not right. How can the destructive power of kinetic energy be compared with the destructive power of an explosion? The destructive power of firecrackers and bullets is ten times less than that?"
