Answer:
The velocity is
Explanation:
From the question we are told that
The initial speed is
The cross -sectional area of the first pipe is
The cross -sectional area of the second pipe is
Generally from continuity equation we have that
So

Resistance is equal to relation between voltage and current.
If we express current:
If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.
So the answer should be C voltage and B zero.
Hope this helps!
