Why is heavy water used as a moderator?
Heavy water is a type of water highly enriched in the hydrogen isotope deuterium. We can conclude the neutron interactions with billiard ball collision, where neutron attracts with nucleus of other atoms & lose energy. If the colliding nucleus size is minute like hydrogen nucleus it will lose maximum energy. If nucleus is heavy the neutron hits the nucleus just changes its direction but not that much alter in the energy of neutron. So we use heavy water as moderator to slow down neutrons.
What do you mean by dispersion of light? Write down the expression for the deviation produced by a thin prism?
Magnetism: 1. There are two types of magnetic pole north and south. 2. Like poles repel and unlike pole attract each other. 3. Magnetic substance produce magnetic field.
a loaded cart has a mass of 227kg. if a 312n force acting at an angle of 30degree to the ground is applied. how much work is done in moving the cart 15meters?
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su

Explain about the working of functional units in ultrasonic pulse echo system. The master timer by the electronic clock triggers the signal pulse generator at ordinary interval
Introduction of physics- Physics Essentials Why do most people believe physics is too hard? Most people get hung up by the feeling that they do not 100% totally understand what
In an electric field a charge (Q) experiences a force F = QE. If charge is positive then force is directed in the direction of field whereas if charge is negative force acts on i
