B. 0.08 megaton of TNT.
C. 6 bombs.
Below is an attachment containing the solution to the question.
Answer:
The disorder in the universe is increasing with time.
Explanation:
The second law of thermodynamics states that the amount of entropy in the universe increases over time. Entropy expresses the number of different configurations that a system defined by macroscopic variables could assume. Therefore, is can be interpreted as a measure of the disorder, or randomness of a system.
Well this is just my opinion but I think because all the plants were gone they cant stop mud from rolling into it. Also when it rains the trees wont suck up the water, that will make it over flow and release into the land or dirt on the outsides of it. Mixing those two gives mud and it can potentially flow back in the river in largeish masses causing the river to mix with the mud makinging it more muddy. Hope this helps :D
Let's say the velocity at the bottom of the window was "v."
s = v*t + ½at²
2 m = v * 1.3s - 4.9m/s² * (1.3s)² = v * 1.3s - 8.3 m
v = 10.3m / 1.3s = 7.9 m/s
Then the initial speed was
V = √(v² + 2as) = √(7.9m/s² + 2 * 9.8m/s² * 7.5m) = 14 m/s ◄ initial velocity
(after rounding to 2 digits from 14.5 m/s).
