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.
Tipler machine: The solution to Einstein's equations of general relativity which permits time travel. A tremendously dense (that is, on the order of the density of neutron star matter), infinitely-long cylinder that rotates very quickly can form close
Uncertainty principle (W. Heisenberg; 1927): A principle, central to the quantum mechanics that states which two complementary parameters (like energy and time, position and momentum, or angular momentum and angular displacement) can’t both be r
Olbers' paradox (H. Olbers; 1826): If the Universe is infinite, consistent, and unchanging then the whole sky at night would be bright -- concerning as bright as the Sun. The further you stared out into space, the more stars there would be, and theref
Steradian: sr: The supplementary SI unit of solid angle stated as the solid central angle of a sphere which encloses a surface on the sphere equivalent to the square of the sphere's radius.
What is the reason that the tea kettle sing? Briefly state the reason.
The molecules of many dielectrics possess an electric dipole moment without having an external electric field. In such molecules centres of their positive and negative charges are displaced with respect to each other and therefore form a dipole. Such materials are kno
Systeme Internationale d'Unites (SI): The rationalized and coherent system of units derived from the m.k.s. system (that itself is derived from metric system) in common utilization in physics nowadays.

Gauss' law for magnetic fields (K.F. Gauss): The magnetic flux via a closed surface is zero (0); no magnetic charges present; in its differential form, div B = 0

div B = 0
Reflection law: For a wave-front intersecting a reflecting surface, the angle of incidence is equivalent to the angle of reflection, in the similar plane stated by the ray of incidence and the normal.
