Physical evidence is the most critical piece of evidence that is used today in forensics.
<u>Explanation:</u>
Evidence, such as items found on-site, is called physical evidence. The physical evidence is hand prints, footprints, fingerprints, cut marks, tidemarks, tool marks and so on. They are carefully collected and analyzed in the laboratory using forensic methods.
According to criminal law, this physical evidence is the king and not biased. It exists despite all expectations and desires. For this reason, it is very important that physical evidence has to be found, uncontaminated, and properly examined.
There is no motion
it is a balanced force
Explanation:
The equation for work done by a system is as follows.
where, = change in internal energy
Q = heat absorbed or released by the system
W = work done by the system
Since it is given that it is an isothermal process. Therefore, .
Whereas internal energy depends on temperature and as there is no change in temperature so, there will be no change in internal energy of the system.
Hence, the equation will be as follows.
0 = Q - W
Q = W
Therefore, we can conclude that for an isothermal process, the work done by or on a system of ideal gas is equal to the change in Q.
