Neutrons are slowed down in a nuclear reactor by – (1) Fissionable Material (2) Moderator (3) Control rods (4) Cooling system

Description : Neutrons are slowed down in a nuclear reactor by – (1) Fissionable Material (2) Moderator (3) Control rods (4) Cooling system

Last Answer : (2) Moderator Explanation: In thermal nuclear reactors, the coolant acts as a moderator that must slow down the neutrons before they can be efficiently absorbed by the fuel. It allows neutrons to slow down to energies where they can easily cause a nucleus to fission.

What are the properties of different atoms that have no protons?

Description : What are the properties of different atoms that have no protons?

Last Answer : Electrons need particles with opposite charge to stay attracted, so need an equal number of protons in the middle. It is possible, however, to have an atom with no neutron. Electrons don’t need neutrons to stay in place.

Metals are good conductors of electricity because - (1) they contain free electrons (2) the atoms are lightly packed (3) they have high melting point (4) All of the above

Description : Metals are good conductors of electricity because - (1) they contain free electrons (2) the atoms are lightly packed (3) they have high melting point (4) All of the above

Last Answer : (1) they contain free electrons Explanation: Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points.

In a Laser (say neon laser) all the atoms emit the light waves of – (1) Same frequency (2) Same amplitude (3) Same phase (4) All of the above

Description : In a Laser (say neon laser) all the atoms emit the light waves of – (1) Same frequency (2) Same amplitude (3) Same phase (4) All of the above

Last Answer : (4) All of the above Explanation: In a Laser all the atoms emit the light waves of same frequency, amplitude and phase. A laser is a device that emits light (electromagnetic radiation) ... photons. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation.
