A) The power delivered to the lines is
And the voltage at which the lines work is
Since the power delivered is the product between the voltage and the current:
We can find the current flowing in the lines:
b) The voltage change along each line can be found by using Ohm's law:
c) The power wasted as heat along each line is given by:
And since we have 2 lines, the total power wasted as heat in both lines is

To solve the problem it is necessary to use the concepts of Orbital Speed considering its density, and its angular displacement.
In general terms the Orbital speed is described as,
PART A) If the orbital speed of a star in this galaxy is constant at any radius, then,
PART B) This time we have, where
is the angular velocity (constant at this case)
PART C) If the total mass interior to any radius r is a constant,
