Answer:
The air moves to the low pressure system creating wind.
Hope this helps! :)
The answer is a sound wave.
Answer:
For the first one, it's B, C, and D. Hydrothermal vents on the seabed, Underwater volcanoes, and the breaking down of rocks.
Second question is C, Fresh water from the glaciers are melting into it.
Explanation:
For the first answer, I can say that they all relate. Hydrothermal vents on the seabed usually break down rocks with their hot water, same as breaking down rocks and the underwater volcanoes as the broken down rocks they broke escape into the water, therefore making it salty.
Second answer, the glaciers are frozen up ice, almost fresh water. So if they melted and mixed into the <u>salty ocean</u>, the ratio of salt and ocean will be different, as the amount of water will be<em> </em>cleaner.
I don't know the others, for this is how much I could help. Sorry if I didn't answer in time!!
Answer:
0.435 M
Explanation:
In case of dilution , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = initial concentration ,
V₁ = initial volume ,
M₂ = final concentration , i.e. , concentration after dilution ,
V₂ = final volume .
from , the question ,
M₁ = 0.725 M
V₁ = 300 mL
M₂ = ?
V₂ = 300 mL + 200 mL = 500 mL
Since, the final volume of solution would be the summation of the initial and final volume.
Using the above formula , the molarity of the final solution after dilution , can be calculated as ,
M₁V₁ = M₂V₂
0.725 M * 300 mL = M₂ * 500mL
M₂ = 0.435 M
Because the penny absorbs the kinetic energy from the impact and releases it back into the environment as heat since the energy cannot be stored as potential energy.
