Answer:
almost 100% positive its B but dont take me up on it
Answer:

Explanation:
We are given that
Mass,
Radius,r=0.8 m

Height,h=2.9 m
We have to find the angular acceleration of the cylinder.
According to question


Where



Substitute the value


Where 


Angular acceleration,
P = 43 * 10^3
V = 12 L
P' =?
V' = 8 L
PV = P'V'
43*10^3* 12 = P' * 8
I know you can do it from here, mate ;)
Many people are in favor of the dam. Hydroelectric power is not as polluting
as other forms of electrical generation. The country is growing quickly, and
its economy is growing. The country must be able to produce more electricity
to meet everyone's needs. However, those opposed say the dams will force
many out of their homes. It will destroy an important wilderness area, and may
damage ecosystems - especially river or fjord ecosystems in Patagonia, since
silt won't be carried down rivers. Many also say that the project helps the
copper mining industry, and they believe that this project will benefit
businesses, not the people of Chile
Isothermal process<span> is a </span>change<span> of a </span>system<span>, in which the </span>temperature<span> remains constant: Δ</span>T<span> = 0. So, if the thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged than this process is isothermal.
</span><span>The Joule's second Law states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. So, isothermal processes are of great interest for ideal gasses.</span>
