Answer:
I = 1.4 [amp]
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.
Therefore:
V = I*R
where:
V = voltage = 14[V]
I = current [amp]
R = resistance = 10 [ohm]
I = 14/10
I = 1.4 [amp]
This is a question volumetric flow rate.
In 1 second, water rises with 0.4 in.
Additionally,
Volume filled in 1 second = A*0.4, A = surface area of the circular cylinder.
Where,
A = πR^2 = π*3^2 = 9π in^2
Therefore,
Volumetric flow rate = 9π*0.4 = 11.31 in^3/s
In terms of liters/s,
1 in^3 = 0.0163871 litres
Then,
11.31 in^3/s = 11.31*0.0163871 ≈ 0.19 l/s
I think the answer is D

<span>B is the correct answer. Neutrons have no charge. In contrast, protons are positively charged and electrons have negative charge. These charges are all relative to each other. The protons and neutrons can be found inside the atom of an element. Electrons float around the outside.</span>
