Why Cadmium rods are given in a nuclear reactor
Cadmium rods are given in a nuclear reactor. Explain why?
Expert
Cadmium rods are given in nuclear reactors as when we start nuclear reactor then more energy is needed to start the reactor, we can’t start nuclear reactor with less energy, the rod is employed specially for stopping contact of neutron particles with the system.
Dalton's law of partial pressures (J. Dalton): The net pressure of a mixture of ideal gases is equivalent to the sum of the partial pressures of its components; which is the sum of the pressures which each component would exert when it were present al
Doppler Effect (C.J. Doppler): The waves emitted by a moving object as received by an observer will be blue shifted (compressed) when approaching, redshifted (that is, elongated) if receding. This takes place both in sound and also el
Hawking radiation (S.W. Hawking; 1973): The theory which black holes emit radiation similar to any other hot body. The virtual particle-antiparticle pairs are continuously being made in supposedly empty space. Infrequently, a pair wil
A dual-wavelength spectrometer uses 780 nm and 830 nm. The molar extinction coefficients for oxy-hemoglobin (HbO_{2}) and deoxy-hemoglobin (Hb) at these two wavelengths are: e_HbO_{2}_780nm = 710 cm^{-1}M^{-1}, e_Hb_780nm = 1075 cm^{}
Centrifugal pseudo force: A pseudo force which takes place whenever one is moving in uniform circular motion. One feels a "force" directed outward from the center of the motion.
