What is nuclear fission short answer?

What is nuclear fission short answer? Nuclear fission is a reaction wherein a heavy nucleus is bombarded by neutrons and thus becomes unstable, which causes it to decompose into two nuclei with equivalent size and magnitude, with a great detachment of energy and the emission of two or three neutrons.

What is the index for refraction?

What is the index for refraction? The index of refraction, n, is the ratio of the speed of light in a vacuum, c, to the speed of light in a medium, c’: One consequence of this difference in speed is that when light goes from one medium to another at an angle, the propagation vector in the new medium has a different angle with respect to the normal.

What is the formula for potential energy is?

What is the formula for potential energy is? The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

What is nuclear radiation made of?

What is nuclear radiation made of? Energy given off by matter in the form of tiny fast-moving particles (alpha particles, beta particles, and neutrons) or pulsating electromagnetic rays or waves (gamma rays) emitted from the nuclei of unstable radioactive atoms.
