Fission and Fusion
What do you mean by Fission and Fusion?
Expert
Fission: It is the breaking down of a Nucleus (that is, not atom) into the smaller nuclei. This is generally induced through a neutron.
For illustration, a Helium nucleus (termed as alpha particle) is divided into two 4He(+2) --> 2H(+1) + 2H(+1)
A huge amount of energy is discharged in the process.
Fusion: This occurs when two nuclei joins to form a big nuclei. A big amount of energy is required to start this. As it is not simple to bring two positively charged nuclei closer. Whenever they combine, a huge amount of energy is discharged.
For illustration: This generally occurs in the stars.
The energy needed to start the fusion comes from the gravitational force among the particles.
Describe why is heavy water employed as a moderator? Illustrate.
Lumen: lm: The derived SI unit of luminous flux, stated as the luminous flux produced by a uniform point source of 1 cd releasing its luminous energy over a solid angle of 1 sr; it therefore has units of cd sr.
Briefly describe the reason why it takes longer to heat a bucket of water than the cup of water?
Photovoltaics (PV): It transform light directly into electricity. The typical current residential installation of 12m2 could produce around 1,300 kWh pa with a peak of around 1.9kW, though larger and more efficient installations are possibl
