Answer:
Explanation:
From the question we are told that:
Fermi energy of conduction electrons
Generally the equation for Fermi energy is mathematically given by
Where
h= Planck's constant

Answer:
376966.991 Joules
Explanation:
Given that :
the height = 12 m
Let assume the tank have a thickness = dh
The radius of the tank by using the concept of similar triangle is :
The area of the tank =
The area of the tank =
The area of the tank =
The volume of the tank is = area × thickness
=
Weight of the element =
where;
= density of water ; which is given as 10000 N/m³
So;
Weight of the element =
Weight of the element =
However; the work required to pump this water = weight × height rise
where the height rise = 12 - h
the work required to pump this water = (12 - h)
the work required to pump this water =
We can determine the total workdone by integrating the work required to pump this water
SO;
Workdone =
=
=
=
=
=
= 376966.991 Joules
