Answer:
Quarks
Explanation:
Quarks, the smallest particles in the universe, are far smaller and operate at much higher energy levels than the protons and neutrons in which they are found.

Answer:
3.25 [atm.]
Explanation:
1) pV=const, where p - pressure, V - volume.
2) According to this formula: 1*130=40*p=const, then p=130/40=<u>3.25 </u>[atm.]
PS. if it is possible check the suggested solution in other sources.
I attached the full question.
We need to write down the law of conservation of momentum and energy.
The law of conservation of momentum:
The law of conservation of energy:
This tells us that potential energy of the compressed spring is used to stop the canon. In other words, the kinetic energy of the canon, after firing is used to do work again the force of the spring.
We can use this two equations to find the velocity of the cannonball:
We can now plug this in the first equation:
Please note that I found this question online with multiple diferent data( mass of the canon, ball etc)
You can use this formula, just plug in your numbers and you will get the correct answer.
