I know that strong nuclear force is a short-ranged force. So, I would like to know how protons became closer during Big bang process. Is it because of very high temperature and pressure during this ?
Please explain me.
Thanks in advance.
In nuclear fusion the nucleons (protons and neutrons come closer because of their high energies. When they come closer to each other in the order of distances of fermi (10^-15 m) nuclear force – the strongest force in nature, comes into play
… Awaiting responses
Say True or false
Every motion made by a vibratory object and then back to its start point is a periodic motion
In this question its not mentioned that the motion is made in equal intervals of time. Please answer the question and justify it ?!

Vibratory motion caused by a restoring force acting on it when disturbed from mean position and inertia is essentially periodic.
Without a restoring force, the to an fro motion may not be periodic.
