Answer:
A. Increase in permafrost thickness
Explanation:
<u>Climate warming (like of 4°C) would increase the active layer thickness (ALT) of permafrost</u>, which can cause changes in the hydrological cycle, ecological processes, and carbon flux in cold regions.
Answer:
Explanation:
We have to remember the <u>molarity equation</u>:
So, we have to calculate "mol" and "L". The total volume is 100 mL. So, we can do the <u>conversion</u>:
Now we can calculate the moles. For this we have to calculate the <u>molar mass</u>:
O: 16 g/mol
H: 1 g/mol
C: 12 g/mol
With the molar mass value we can <u>calculate the number of moles</u>:
Finally, we can <u>calculate the molarity</u>:

Industrialization has historically led to urbanization by creating economic growth and job opportunities that draw people to cities. Urbanization typically begins when a factory or multiple factories are established within a region, thus creating a high demand for factory labor.
The answer: less frequency, causing the pitch to be lowered.
This is known as the Doppler effect. When you have an object that is producing sound while moving, the side that it is moving towards to will have waves that will become a bit more squished together, while the other side that it is moving away from will have waves that are spaced a bit more apart from each other. The only determining factor in this is the magnitude of the speed, so the faster the object is moving towards or away from you, then the more severe pitch change the object will have.
In this case, it's just asking in general what would happen if the horn was moving away from you while it was giving off sound waves. Therefore, since it is moving away from you, its sound waves are a bit further apart, resulting in a lowered frequency and pitch.
