What is the principle of a megalith? What is the principle of a megalith? Urgent!!!

Buoyancy is related to the volume of water discharged, which is the volume of the boat when it is loaded on the ship, and the volume of the stone plus the volume of the boat under the boat, the latter is subject to more buoyancy.

Typing is not easy, such as satisfaction, hope.

The larger the volume, the stronger the buoyancy.

I haven't heard of it, the landlord misunderstood.

The little one is called a boat! The big one is called the ship! There is human paddling!

There are sails blowing! There is still a pull as a last resort! A long history!

Therefore, there is the beauty of the ancient boat and the wild ferry! The modern ship has followed the pace of the Industrial Revolution the most! From the steam engine to the internal combustion engine!

Up to nuclear power! Today is a boat rowing and playing! Big boats don't have to be rowed!

Boats are by far the largest means of transportation for mankind! Although it is not fast enough to reach the speed of planes, trains, cars! But its carrying capacity is beyond the reach of the former!

You ask how the ship works! That can only be said to be the loading and running of the ship! According to Archimedes' law!

The buoyant force experienced by an object in the water is equal to the volumetric weight of the object discharging water! We make the object into a cavity container that stretches as far as possible! Make it as much as possible to drain the water into it!

This container can carry less than the weight of the buoyant cargo! This is the ship! A carrier container that can float on the water!

The power of the boat is easy to say! It doesn't matter if it's a human paddling or the wind blowing! Or modern power machinery! As long as you can make this floating container move by push or pull in the water!

No matter what kind of boat, it has its own buoyancy (buoyancy is equal to the weight of the liquid discharged by the object), floats on the water, and uses power (diesel engine, gasoline engine, electric motor, nuclear power, etc.) to drag the propeller, and the propeller rotates to push the water to produce force, so that the boat moves in the opposite direction (equivalent to the principle that the fan blades rotate to make the air flow produce wind).

The tracking principle of shipborne satellite antennas is the same as that on land, which is a comprehensive tracking and positioning including many technologies, the difference is that the ship can sail on the ocean to change positions, find the best position for tracking and positioning, as well as command and exchange data, while the position of the land base station is fixed.

Tracking and other functions are also achieved through electromagnetic waves, both active and passive.

The active type is to actively emit radar waves or electromagnetic waves of a specific wavelength, collect data by accepting the beams emitted, and then process the data through the computer (including the information provided by the Doppler effect), and finally obtain various information such as the position and speed, orbit and even attitude of the artificial satellite or other spacecraft, and can also actively use the electromagnetic waves of a specific wavelength (frequency) to encrypt and send signals for the command of satellites or other spacecraft. Make the spacecraft adjust accordingly or even self-destruct.

The passive type is to receive the encrypted information sent by the spacecraft at a specific frequency, and obtain the information through computer processing, including the situation inside the spacecraft, which cannot be obtained by active means at present, and is no different from the active type.

Only by combining the two modes of active and passive and cooperating with each other can the tracking station and the spacecraft interact perfectly, so that the spacecraft can successfully complete the scheduled and temporary additional tasks.

If the iron rods are not closed between them, then the volume of the iron rods is counted, and the enclosed space is not counted.

Buoyancy, the magnitude of buoyancy is determined by the amount of water discharged. The more volume an object has immersed in water, the more water is expelled. The smaller the volume, the heavier the object is more likely to sink, and the larger the volume, the lighter the object is more likely to float.

Boring, it doesn't have a draft, and it adds weight. Look at how this space is defined.

Look at how this space is defined, it adds weight, and it is not boring.

Take a closer look at Archimedes' principle!

The buoyant force experienced by an object in the water is equal to the gravitational force experienced by the water it dispels. The gravity of the water discharged from the part below the waterline (equal to the buoyancy experienced by the ship) is sufficient to balance the gravity of the ship itself, so that the boat can float on the water.

Unlike household air conditioners, they are composed of four large compressors, condensers, expansion valves, and evaporators. The specific refrigerant is compressed into a high-temperature and high-pressure gas through the compressor, enters the condenser to become a high-pressure and low-temperature liquid, then becomes a low-temperature and high-pressure gas through the expansion valve, enters the evaporator to absorb heat and becomes a high-temperature and low-pressure gas, and then enters the compressor circulation. After that, the fan blows the hot air through the evaporator to cool and send out the cold air.

In the case of heating, high-temperature steam is supplied to the air through the heat sink and sent out by the fan.

Powered by an internal combustion engine or other engine.

The propeller blades rotate and exert a force on the water.

The water is pushed backwards and then reacted by the water to get the forward force.

The propeller is driven by the main engine, driven to the shaft, transmitted to the blade through the tail shaft, and the main engine is connected to the shaft is a big gear. There are combined type, integral type, and strip pitch type!
