The lung volume that represents the maximum amount of exchangeable air is the: <u>vital capacity</u>
<u></u>
The vital capacity is the volume of air that can be taken into the lungs by inhaling and expelling air by inspiration and expiration.
<h3>What are the lungs? </h3>
The lungs are one of the largest organs of the body and are in charge of the respiratory function. They have a spongy appearance and are located in the thorax, protected by the ribs, one on each side of the heart.

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.
Right, as you mentioned in the comments, you find 
by plugging in the different values of 
.
For 
, we have
Similarly, for 
, you get
Answer:
This is because these metals are used for minting (making) coins.
