Acoffee pot in the form of a circular cylinder of radius 3 in. is being filled with water flowing at a constant rate. if the water level is rising at the rate of 0.4 in./sec, what is the rate at which water is flowing into the coffee pot? (round your answer to two decimal places.)

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

Iam looking for this answer too!

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
