Explanation:
Physical evidence is the most critical piece of evidence that is used today in forensics.
<u>Explanation:</u>

Answer:
Minimum uncertainty in velocity of a proton,
Explanation:
It is given that,
A proton is confined to a space 1 fm wide,
We need to find the minimum uncertainty in its velocity. We know that the Heisenberg Uncertainty principle gives the uncertainty between position and the momentum such that,
Since, p = mv
So, the minimum uncertainty in its velocity is greater than . Hence, this is the required solution.
The big bang never occurred. That's all lies. Doctrine...But if you really wanted an answer, its 13.7 billion years ago.
