Answer:
The concentration downstream reduces to 0.03463mg/L
Explanation:
Initially let us calculate the time it is required to fill the lake, since for that period of time the pollutant shall remain in the lake before being flushed out.
Thus the detention period is calculated as
Now the concentration of the pollutant after 14.872 days is calculated as
where
is the initial concentration
't' is the time elapsed after which the remaining concentration is calculated
k is the dissociation constant.
Applying values we get
Answer:
Explanation:
For this exercise you can use the Pythagorean theorem to find the magnitude of the resultant displacement.
Then:
You can observe that the square of the displacement is equal to the sum of the square of the horizontal displacement and the square of the vertical displacement.
Since the pirate walks 37.0 meters north and then turns and walks 8.5 meters east:
Substituting values and solving for "d", you get:
