Explanation:
8. Which process(es) of the water cycle—precipitation, evaporation, condensation, runoff, percolation or transpiration-might contribute to the addition of pollutants to rivers, lakes, and oceans? Why? Precipitation and runoff would be the most responsible processes.
<span>The second law of thermodynamics states that the entropy of any isolated system always increases.
So the paper tends to approach high entropy
Answer is C</span>
Answer:
The first is the closest in absolute values.
The second two are vague and the last is approximate.
Answer: 588 joules
Explanation:
Work is done when force is applied on an object over a distance ( whether vertical or horizontal). It is measured in joules.
Thus, Workdone = Force X distance
- Vertical distance to be moved by the brick = 12 metres
- Mass of box = 5kg
- Acceleration due to gravity when box was lifted represented by g is a constant with value of 9.8m/s^2
Now, recall that Force = Mass x acceleration due to gravity
i.e Force = 5kg x 9.8m/s^2
Force = 49 Newton
So, Workdone = Force X Distance
Workdone = 49 Newton X 12 metres
Workdone = 588 joules
Thus, 588 joules of work was done.
