Research into nuclear fusion will likely require a large investment of time and money before it might be used as an energy source. which statement best describes the benefits that would make the investment worthwhile? a. fusion requires a large amount of energy and occurs in stars. b. fusion produces large amounts of energy, and the fuel is found on earth. c. fusion produces no radioactive waste, and the fuel is plentiful. d. fusion requires little energy to begin and would continue through a chain reaction.

C. Fusion produces no radioactive waste, and the fuel is plentiful.

Explanation:

Nuclear fusion occurs when two smaller nuclei combine together and fuse into a heaver nucleus. In the process, part of the mass of the original nuclei is converted into energy, according to the Einstein's famous equation:

and therefore a huge amount of energy is released in the process.

The simplest example of nuclear fusion is the fusion of two nuclei of hydrogen into a nucleus of helium. This is the process that occurs also in the core of the stars. Nuclear fusion does not produce any radioactive waste (contrary to the nuclear fission), and also, we have unlimited supplies of fuel on the Earth: in fact, the main fuel of the nuclear fusion is the hydrogen, which can be extracted from the water.

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
