Some. And it should be said that people sit on chairs precisely by taking advantage of inertia. The person sits still in the chair, and the person will continue to remain in the original state of rest due to the action of inertia.
Otherwise, if there is no credit of inertia, people sitting on a chair will inexplicably move involuntarily, and the same is true for other objects, stationary objects will not obediently remain still, and moving objects will stop uncontrollably. It is no exaggeration to say that if the object loses its inertia, the world will be chaotic, and the order of the static and the moving will be lost.

Many students have the misconception that inertia is the inertia when an object continues to move after it has been thrown, which is just a manifestation of inertia. In fact, inertia is a fundamental property of an object (including people, of course), and no matter what state of motion the object is in, the object has a definite inertia (only related to the mass of the object). There are two misunderstandings to be corrected by asking questions here: one is that inertia is not generated, but inherent in the object itself; The second is that inertia has nothing to do with the state of motion of the object, whether the object is stationary (relative) or doing any motion.

Yes, there will be inertia at all times, this is the law of inertia.

I don't know what inertia you're talking about, in general, as long as there is mass, there is inertia.

There is a cylinder in the pneumatic chairlift, the piston pneumatic rod in the cylinder moves up and down to control the chair lifting, and the regular manufacturers use nitrogen filling, the concentration is generally more than 99%, and the pressure is about one or two atmospheres. This kind of regular chair lift, generally there are three situations that may occur: first, the nitrogen purity is insufficient, in the case of high temperature environment or too frequent friction, it will lead to a sudden rise in cylinder temperature and pressure, which may occur; Second, the cylinder container wall is not strong enough or the material is poor, which may occur; The third is that the sealing is not tight, resulting in gas bursting out.
In order to reduce costs, some black manufacturers fill even high-pressure air, which is more likely to cause.

The best position of the chair to buy a computer chair that can be adjusted up and down is about 90 degrees with both hands hanging down and bending the elbows to the keyboard for typing, and the legs are naturally sitting on the ground, and the hips are only Zheng and Lingsong's calves are 90 degrees, depending on the height of your computer desk, if you can't reach the best position, the preferred position of the hand.
Researchers in the United States have done experiments. The results showed that if a person did not sleep for 40 consecutive hours, the mental ability to process numbers, correctly say the name of a color, and recall a certain event would be significantly reduced. If you don't sleep for 50 hours, your mobility, physical strength, personality and other aspects will decrease; If the subject is placed alone in a room, the subject will experience psychotic hallucinations and child-like behavior; If you don't sleep for 70 hours in a row, your concentration and feelings will be paralyzed; After 120 hours, the person will fall into a state of insanity. >>>More
First of all, this involves the problem of a model of the universe, usually in the model of the universe, whether it is a 10-dimensional or 26-dimensional model of the universe, the time dimension is usually 4 to 6 dimensions. The expansion of low latitudes in a certain direction at high dimensions. This is easy to understand in terms of the spatial dimension of one to three dimensions. >>>More
If we want to guess that rats are extinct, many species on Earth are affected. For example, the extinction of rats has led to a massive increase in insect populations, damage to plant plants in the fields, and a drastic reduction in food, resulting in many humans starving to death. It's also possible. >>>More

Broadly speaking, plants can poop. However, it depends on how we define poop, and according to animal habits, only some plants meet the behavior of pooping. After all, most plants do not have defecation organs and cannot excrete waste products from their bodies like animals. >>>More
