Answer:
The most critical policy issue facing America today is the rivalry between Democrats and Republicans, Antifa and Trump supporters, left and right, progressives and conservatives; in short, the inherent social conflict in American society today, which is creating a series of increasingly serious social confrontations among the nation's citizens. Clear examples of this situation are the assassination of George Floyd, the assault on the Capitol by Trump's followers, the constant excesses of Antifa in his mobilizations, and the growing tension between both political groups.
Unfortunately, our government is not taking the necessary measures to unite the nation, but rather each political party operates according to its own interests, increasing the severity of the problem more and more.
Answer:
0.027 cubic ft/min
Explanation:
Volume of water is V=V(t) Depth of water is h=h(t)
The relationship between V and h is
V=π/3.r2.h
Let
h0= the height of the cylinder = 24ft, r0= the radius of the opening = 10ft.
Since water level (h) rise with respect to flow rate we find an expression for r and substitute into V
r/h = r0/h0= 10/24 = 5/12
r = (5/12) h,
Substitute for r in V
so,
V=1/3.π.(h2)square = 1/3.π. 25/144.(h3)
When
h= 16ft
and dV/dt = 20ft3/min
,
dV/dt =1/3*π*25/144*h3*(dh/dt)
20ft3/min= 1/3*π* 25/144*h3*(dh/dt)
20 = 1/3*π*(16)3.(dh/dt)
Make dh/DT subject of formula
dh/dt=(20*3*144)/(25*π*4096) = 8640/321740.8
=
dh/dt= 0.027 ft3/min
