The deforestation is the removal of forests and trees.
The result of deforestation is the loss of vegetation. Forests and trees are very important in the process of using the carbon dioxide through the photosynthesis. They balance the amount of carbon dioxide in the air.
So, deforestation affects the atmosphere balance because it increase the amount of carbon dioxide releases in the atmosphere. This carbon dioxide holds the heat in the air and leads to global warming.
I believe the answer is D.
Answer:
13.09 s
Explanation:
From the question given above, the following data were obtained:
Power (P) = 275 W
Work (W) = 3600 J
Time (t) =?
Power is defined as the rate at which work is done. Mathematically, it can be expressed:
Power (P) = Work (W) / time (t)
P = W/t
With the above formula, we can obtain the time taken for the swimmer to accomplish the work. This can be obtained as follow:
Power (P) = 275 W
Work (W) = 3600 J
Time (t) =?
P = W/t
275 = 3600/t
Cross multiply
275 × t = 3600
Divide both side by 275
t = 3600 / 275
t = 13.09 s
Thus, it will take the swimmer 13.09 s to accomplish the work.
I translated it so I could help, but please try putting the question in English.
You are supposed to use charles' law here. V1/T1 = V2/T2. Temps should be converted to kelvin, so K = C + 273. You are finding V2, so solving for V2 makes it V1*T2/T1 = 0.5 * 313/293 = 0.534 liters
<em>Answer: I think it is C</em>
