Chapter 799

Then the next question we should consider is the speed of the earth’s rotation and the time of the earth’s rotation, as well as the trajectories of some asteroids around the earth.

First of all, the speed of the earth’s rotation depends on the conversion time of this connector and its scheduling time.

The rotation time of the earth is due to the change time of the connector, the reaction of the magnetic field during rotation and the change of the magnetic field to determine the conversion time of the connector. The material and appearance of the 21 connector are different for different magnetic fields, so This is a very serious, serious and careful work.

A lot of information about the earth came to Jiang Cheng’s mind.

First of all, the earth is one of the eight planets in the solar system, and in the order of near and far from the sun, the earth is ranked third, and it is also the terrestrial planet with the largest diameter, mass, and density in the solar system, about a little bit away from the sun. 500 million kilometers, the turning of the earth is that the earth rotates from west to east, and the earth is also revolving around the sun.

The earth is now 4 billion to 5 billion years old. Of course, this is only an approximate value. Moreover, the earth has a natural satellite, which is our moon. The two form a celestial system called the earth-moon system. It originated in the primordial solar nebula 4.6 billion years ago.

Jiang Cheng thought for a while, the moon shouldn’t have much influence, and it shouldn’t be divided into the scope of his own research for the time being.

“Smart computer, check the value and shape of the earth.”

“Okay, Master. The earth’s equatorial radius is about 6,378 kilometers, the polar radius is 6,356 kilometers, and the average earth’s radius is about 6,371 kilometers, the equator Its circumference is approximately forty-nine kilometers, and it is an irregular ellipsoid with slightly flattened poles and slightly bulged equator.”

“What about the structure of the earth?”

“The earth has a core, crustal, and crust structure inside the earth, and there is also a hydrosphere, atmosphere, and magnetic field outside the earth.”

Jiang Cheng suddenly missed China. As a planet, the earth is currently the only celestial body known to have life in the universe, and it is the home of millions of creatures, including humans. It is absolutely necessary to protect the earth and defend your home. .

Jiang Cheng intends to first study the relationship between space and time, that is, the relationship between space and the rotation of the earth, and to put it bluntly, what kind of connection does it take to connect a transmitter from the earth in space?

The rotation of the earth is the rotation of the earth around its rotation axis.

“Where is the fastest rotation of the earth?”

“Report to the owner that the line of rotation at the equator is the fastest.”

“Then how long does it take for the earth to rotate once?”

“The radius of the earth is 6,377 kilometers, 517 miles, and the earth rotates once every twenty-four hours.”

After listening to the numbers reported by the smart computer, Jiang Cheng started to calculate in his mind. He is indeed a mathematics genius. He has a special sensitivity to numbers, and he can calculate it only with his brain.

“So, from this we can calculate that the linear velocity of the earth’s equator is about 1,668 kilometers per hour, which is 463 meters per second.”

“Yes, master, that’s right.”

“Then the linear velocity of the equator is so fast, people there will definitely not be thrown out?” Jiang Cheng had this question quickly in his mind. .
