Answer:
is absorbed by other objects.
Explanation:
energy can never or formed or destroyed, it just changes from one form to another.
Answer:
The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules. This means that you need to take more breaths in order to get the same amount of oxygen as you would at lower altitudes. The higher the elevation, the more difficult breathing becomes
Explanation:
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
The Proclamation changed the purpose of the war into one of freeing slaves completely, making the long war into one about wether or not slavery would remain in place . The South claiming that they needed slaves to work on their plantations and needed slaves to help around was a major part of the war . They wanted to continue on this racist act of holding “different” people under their feet. Many say now that the this was not a reason for the war nor the separation between the north and south but when looking back at every statement made by every southern state slavery is mentioned for their uprising .
