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

A rock at the edge of a cliff has potential energy because it isn't in motion, but is located in a place that motion could occur in the near future.
A. When your fire a bullet into the air, it typically takes between 20 and 90 second for it to come down,depending on the angle it was fired at,its muzzle velocity and caliber.
<span>In order to make 4 complete revolutions in 4 seconds, the wheel must have a constant angular acceleration of 144° (or 2.5 radians) per square second, hence after 8 seconds the wheel will have made 14,4 revolutions, or 5184° in total.</span>
