Why is heavy water employed as a moderator
Describe why is heavy water employed as a moderator? Illustrate.
Expert
Heavy water is highly enriched in the hydrogen isotope deuterium. We can evaluate the neutron interactions with billiard ball collision, where the neutron collides with nucleus of other atoms and lose energy. When the colliding nucleus size is small such as hydrogen nucleus it will lose the maximum energy. When nucleus is heavy, then the neutron hits the nucleus just alters its direction however not that much change in the energy of neutron. Therefore we use heavy water as moderator to slow down the neutrons.
Briefly describe the applications of the nmr spectroscopy?
Photoelectric effect: An effect described by A. Einstein that demonstrates that light seems to be made up of particles, or photons. The light can excite electrons (termed as photoelectrons in this context) to be ejected from the metal. Light with a fr
Newton: N (after Sir I. Newton, 1642-1727): The derived SI unit of force, stated as the force needed to give a mass of 1 kg of an acceleration of 1 m/s2; it therefore has units of kg m/s2.
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
Describe briefly all the Law of Machines?
Ideal gas equation: The equation that sums up the ideal gas laws in one simple equation, P V = n R T, Here V is the volume, P is the pressure, n is the
Cosmological constant (Lambda): The constant mentioned to the Einstein field equation, proposed to admit the static cosmological solutions. At the time the present philosophical view was steady-state model of the space, where the Universe has been aro
