The Sun is a renewable energy source, which, if used through so-called photovoltaic panels, allows you to significantly reduce the use of fossil fuels. In Italy, 2000 kWh of solar energy is collected every year for each square meter of surface, which is the equivalent of 1.5 "barrels of oil" per square meter.

Taking into account the map, which represents the solar energy available in the
capitals of southern Italy per square meter, determines:
1) how many barrels of oil could be saved in one year;
2) how many barrels of oil are saved annually with a photovoltaic panel
of 5 square meters
installed in Naples. C1

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
