<span>The amount of dissolved oxygen in water may decrease
because of the increase in organic matter in the water. <span>Aquatic organisms breathe and use oxygen. Large amounts of
oxygen are consumed by the decomposition of bacteria (when there are large
amounts of dead matter to decompose, there will be a significant number of
bacteria). Examples: dead organic matter (algae), wastewater, garden waste,
oils and fats, all this results in a decrease in dissolved oxygen in the water.</span></span>
The last option would be I think
Answer:
Explanation:
Given:
a = 3.10 m/s^2
vf = 12.4 m/s
vi = -6.2 m/s
t = (vf - vi)/a
= (12.4 + 6.2)/3.1
= 6 s
displacement = (vf - vi)*t
= (12.4 + 6.2) * 6
= 111.6 m.
