Answer:
The maximum electric power output is 
Explanation:
From the question we are told that
The capacity of the hydroelectric plant is 
The level at which water is been released is 
The efficiency is
0.90
The electric power output is mathematically represented as
Where
is the potential energy at level h which is mathematically evaluated as

and
is the potential energy at ground level which is mathematically evaluated as


So
here 
where V is volume and
is density of water whose value is 
So

substituting values


The maximum possible electric power output is

substituting values


Ok srry bout last time but the answer is A) kelvin: time the reason is because everything else is a SI. Hope this helps and TURTLE
Protons
Explanation:
In a neutral atom, the number of electrons equals the number of protons in the atom.
- Electrons are the negatively charge particles in an atom
- Protons carry positive charge.
- Neutrons do not carry any charges.
Protons and neutrons are contained in the nucleus of an atom they determine the mass number of the atom.
In a neutral atom, the number of protons and electrons must be the same.
A charge atom called an ion is one that has lost or gained electrons.
