    What is the voltage of the car in Ohm's Law Application Problem 1?

    1. A car, 5 km distance from a station, take 100 A over a 100 mm hard drawn copper trolley wire having a resistance of 0.270 ohm per km. The rail and ground return has a resistance of 0.06 ohm per km. If the station voltage is 750 V, what is the voltage of the car? Homework Equations I...

    How Do You Eliminate the Arbitrary Constant in the Equation x^3 - 3x^2y = C?

    I would like to eliminate the arbitrary constant in this equation: 2. x^3-3x^2y=C 3. I tried differentiating with respect to x: x^3-3x^2y=C 3x^2-(3x^2+6xy)=0? This is where i don't know what I will do next. I don't know know what the result of differentiating C with respect to x. I assumed...
