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

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
