Answer:
acceleration due to gravity: g= 9 m/s^2
Explanation:
m=2kg
w= 18 n
w=mg
g= w/m
g=18/2
g= 9m/s^2
As water evaporates off salt water, the water gets saltier, and dissolved oxygen in the water reduces.
<h3>Dissolved oxygen and solute concentration</h3>
There is an inverse relationship between the dissolved oxygen in water and the concentration of solute.
Thus, as water evaporates off the tidal pool, available free oxygen decreases accordingly just as the water becomes more salty.
In other words, the more water in a solution, the more free oxygen, and vice versa.
