Hello. I want to ask for advice. I know I probably won't understand it anyway, but maybe some information will help me. I did not find a solution to this problem on the Internet, which in itself I do not understand. We moved the cabinet and I can't calculate how much the weight on the opposite...

Okay, thank you then.

I would say that the force of the vacuum is greater than the force of gravity.

The value of the atmospheric pressure does not seem to me to be correct 1013 HPa and can be recalculated as approx. 1kg/cm2 (is it true?), but it does not seem that such a pressure would be manifested by any resistance or any deformations, for example on a folded sheet of paper. It is possible...

That I blocked the drain with a match.

I would not count the torque, I would like to stick to the classic distribution of forces by vectors using trigonometry and crank calculation. Unfortunately, I don't have such an opportunity to understand everything. This movement seems unrealistic to me. I saw how much work it can be to raise...

I'm sorry I don't have enough experience to counter but it seems to me from a layman's point of view that if a gas has a different density it can't have the same number of molecules and the distance between them can't always be the same. Apparently this is being tried with some reactions and a...

https://cs.wikipedia.org/wiki/Voln%C3%BD_p%C3%A1d I think zero mass means the zero begin speed. I use translator. I don't know much about the formula and I don't exactly understand the shortening in the article. The formula and reasoning must be wrong. It is clear that when I say that as force...

Hello. I read on Wikipedia that when a body is in free fall from zero mass, its mass does not matter and two bodies of different weights will fall at the same speed. I think this is not correct. If I consider that the bodies are in a weightless state and the gravitational force will act on them...

How can I calculate the leverage on the lower leg during a squat and the force that the thigh muscle must exert in order for the body to perform the squat. Can you help me?

I cannot explain that if I divide a magnet with a north and a south pole into 2 parts, the force in it rearranges itself into 2 poles. Where is the center of power? How can I explain the principle of magnetic force if I don't take it as a matter of fact.

I have a trivial question. What causes the direction in which the water in the spout turns? They say it's according to the Earth's hemisphere, but I don't really believe it and I'm looking for other reasons. Finally, even this reason would have to have some explanation.

The law states that in the same volume at the same pressure, the number of any gas is the same. It seems to me that this law does not apply, since each molecule of a different gas must have a different size, and between the molecules there will also be different sizes of pressure force, density...

I would like to ask here some questions that came to my mind in connection with physics and expand my opinion and outlook in this area.
