Question: The source voltage Vs = 1 5 volts The total length of the potentiometer, Lp = 4 0 cm The total resistance of the potentiometer

The source voltage Vs =15 volts
The total length of the potentiometer, Lp =40 cm
The total resistance of the potentiometer Rp =80 k
The cross-section area of the fuel tank A =3000 cm2
When the tank contains 75 liters of fuel, the gauge reads 6 volts.
The following statements have been made:
One
The minimal volume of fuel, which can be measured with this gauge, equals 27 liters.
Two
When the tank contains 59 liters of fuel, the gauge reads 3 volts.
Three
When the gauge reads 5 volts, the tank contains 67 liters of fuel.
Allow 5% error margin.
Choose the correct conclusion:
