Answer:
R=3818Km
Explanation:
Take a look at the picture. Point A is when you start the stopwatch. Then you stand, the planet rotates an angle α and you are standing at point B.
Since you travel 2π radians in 24H, the angle can be calculated as:
t being expressed in hours.
From the triangle formed by A,B and the center of the planet, we know that:
Solving for r, we get:
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
And the voltage at which the lines work is
