Kinetic energy in an orbit. The kinetic energy of an object in orbit can easily be found from the following equations: Centripetal force on a satellite of mass m moving at velocity v in an orbit of radius r = mv2/r. But this is equal to the gravitational force (F) between the planet (mass M) and the satellite: F =GMm/r2 and so mv2 = GMm/r. But kinetic energy = mv2 and so:
I believe the power company would be responsible for it, but they would of course charge you. Their business is delivering power and not contracting; ours seemed pretty fair running a natural gas line/meter/etc. 430 feet for $2000.
In today\'s environment, it costs the RZD (Russian Federal Railways) approximately $750,000 - 800,000 per kilometer to put a two-track line under AC wire (25kV, 50Hz). am talking just the infrastructure....poles, wires, labor, substations. How much did the New Haven-Boston electrification project cost (and I\'m looking for the figure that represents the direct costs for the electrification).
