"How much energy was produced when the Anglis meteorite hit the planet?" Eve's curiosity is aroused by the topic of a meteorite hitting the planet.

"That's ...... question?"

Da Liu pushed his glasses and analyzed: "This issue should be discussed separately, meteorites hit planets, first kinetic energy, and then impact the ground is also likely to explode."

"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 kinetic destructive power in one direction is much higher than that of an explosion."

Someone asked in confusion: "Is the power of the explosion less than the kinetic energy?" Right? ”

After thinking for a moment, Da Liu explained: "In fact, in the impression of many people, there will be an illusion, and they subconsciously think that the explosion is very terrifying.

"But in fact, the destructive power of an explosion is actually quite average compared to the kinetic energy in one direction.

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

"The destructive power of the bullet after it is discharged comes from the gunpowder inside the cartridge case.

"So, if we poured out the gunpowder out of the eggshell and made a firecracker, what do you think of the power?"

This example is indeed very easy to understand, the gunpowder in the shell, if made into a firecracker, will not be too powerful if it explodes directly in the hand.

Da Liu continued: "That's easy to understand, right? Using the gunpowder of a bullet to make a firecracker, the most destructive power is the level of skin breaking.

"However, such a light of gunpowder, placed in a bullet, converts energy into kinetic energy when it explodes, and when the bullet is fired, it can pierce the hardest skull.

"From this it can be seen that kinetic energy is more destructive than an explosion.

"In fact, the destructive power of the explosion is also mostly reflected in the shock wave, in fact, it is still kinetic destructive force, but it is just a diffuse shock wave, and the farther the range, the less damage it causes."

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

Eve tapped her chin with her finger and said thoughtfully, "In this way, it is indeed the destructive power of kinetic energy that is stronger." No wonder an asteroid with a diameter of 10 kilometers hit the Earth and wiped out all the dinosaurs. ”

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

"Let's calculate the kinetic energy of this meteorite when it hits.

"Based on the exploration and analysis of the crater, we can probably conclude that the diameter of the Angelis meteorite is about three to five kilometers......

"Combined with the density of the magnetite and a portion of the rock, we can calculate an approximate mass.

"For the sake of ease of calculation, let's take an integer, the mass of the Anglis meteorite, 30 billion tons.

"Then there's the velocity of the meteorite when it falls.

"Earth's meteorites fall at a rate of about 20 kilometers per second to 70 kilometers per second.

"Judging from the degree of fragmentation of the meteorite fragments in the Anglis Crater, we can speculate that the impact velocity of this meteorite should be low.

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

The final answer was 6×10^21 joules.

"6 times 10 to the 21st power, which is 60 trillion joules, converts to a higher unit, 600,000 joules."

Fang Yuan couldn't help but take a deep breath when he heard this number.

600,000 joules, which is a terrifying order of magnitude.

Eve couldn't help but start nodding her fingers: "The captain's dark matter dragon fist can hit 115 trillion joules, so ......"

She tried to figure out the difference, but found that the value was too big and she couldn't figure it out.

Fang Yuan hurriedly coughed and said, "What, let's calculate the power of the little boy." ”

The real values are too different to be compared.

After all, an asteroid with a diameter of five kilometers has a mass of 30 billion tons, and the mass alone is not comparable to human beings.

However, if it is the nuclear bomb called "Little Boy", it is somewhat comparable.

The nuclear bomb called "Little Boy" in the last century, dropped on an island, almost ended a war.

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

"The little boy is 15,000 equivalents, converted into joules, that is, 63×10^12 joules, that is, 63 trillion."

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

Eve began to count his fingers again: "The little boy with 63 trillion joules, the power of the captain's dark matter dragon fist is 115 trillion joules......

"Hey, it's pretty much the same. Captain, you can punch out the power of two nuclear bombs. ”

Numerically, the power of Fang Yuan's punch was indeed equivalent to twice the energy generated by the "little boy's" explosion.

However, the problem of kinetic destructive power and explosive destructive power remains.

The Dark Matter Dragon Fist is a one-way kinetic power, while a nuclear bomb explosion is a diffusion 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 destructive power of the 115 trillion joules of the dark matter dragon fist at one point is far greater than that of the "little boy".

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

Therefore, if it is used to deal with the tide of star beasts, it is actually a nuclear bomb like "Little Boy" that is more effective, and the Dark Matter Dragon Fist is more suitable for killing high-level star beasts.

Fang Yuan said with a serious expression: "One punch to hit twice the power of a nuclear bomb, this is not enough, I said what else do you want from the staff?" ”

The person in charge of the assessment team said expressionlessly: "'Little Boy' is already a fission bomb in the last century, with a yield of only 15,000 tons, and now the commonly used nuclear weapons of mankind are hydrogen bombs, most of which have a yield of more than 500,000 tons, so if you compare, it is not enough." ”

Eve argued, "No. 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 not too much to be ten times worse, right? ”
