So, if I understand correctly, depending on the speed at which the proton strikes the target and therefore on the type of pair of particles created, one of these situations can occur (intact, destroyed, split into quarks). For a proton-antiproton pair created by the collision of a very...

Hello, i was wondering, during the pair creation caused by the collision between a very energetic proton and a target (atomic nucleus) in a particle accelerator, what happens to the very energetic proton after the collision? Is it destroyed, intact, split into quarks or something else? Thank you!

So if I summarize, as shown by the formula, pressure only depends on height (difference in height),the volumic mass of the liquid and gravitational acceleration. The angle of a pipe and the total mass of liquid in a system (water tower, aquarium, etc.) do not change the pressure at the base of...

I read the link you sent me and I think I understood. The drawing and explanation I did in my previous post shows the same thing that is explained in your link but less well. There is even an image that shows the same thing as my drawing but much better:

I quickly made a drawing to illustrate my previous message, it will surely be clearer: If I understand correctly, in a water tower, the water pressure in zone A will only be affected by the water in zone D. The water in zones B and C will not affect the water pressure in zone A.

Thank you everyone! If I understood correctly, what determines the water outlet pressure of a water tower is only the water that has above the base of the pipe (which descends to the bottom of the tower) , so the water in the tank at the very top that is not directly above the base of the pipe...

Hello, I was wondering, for a fixed amount of water, why when the height of a water tower increases, the water pressure at the outlet of the pipe at the base of the tower increases ? I have often read on the internet that it would be caused by the weight of the water above the water at the base...

Are you sure there is more mass at the equator than at the poles due to the Earth's rotation? Isn't it rather that matter is less dense at the equator than at the poles because of the centrifugal effect of the Earth's rotation, which would explain why the Earth is a flattened spheroid?

But then does the equatorial bulge of the Earth cause the nodal precession simply because part of the mass at the equator is raised and pulls the satellite a little more towards the equator than towards the center of the Earth or because there is a little more mass at the equator than at the...

For a satellite in circular polar orbit around the Earth, can the equatorial bulge also cause a slight acceleration of the satellite as it heads towards the equator and a slight deceleration as it moves away from it towards a pole? (I hope my question is understandable)

Hello, the artificial satellites that orbit the Earth with an orbital inclination greater than 0 are all subject to the nodal precession caused by the equatorial bulge of the Earth at the equator. But what I don't really understand is that at the equator the gravity is a little less strong than...

Thanks to everyone !

Hello, I noticed while trying to calculate the stardart gravity acceleration of the Earth that I never arrived at the defined value of 9.80665 m/s2 no matter that I calculate it with the equatorial radius, the polar radius, mean radius or the average of the equatorial and polar radius. With what...

Thank you all for your explanations!

If I understand correctly all the elementary particles that formed the matter that exists today were created from the energy of the inflation field
