Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing the host atoms farther away, or by pulling them in, as depicted. The cross section that scatters the electron is the lattice region that has been elasticity distorted by the impurity (the impurity atom itself and its neighbouring host atoms), so that in this zone, the electron suddenly experiences a force due to sudden change in PE. This region has a large scattering event from impurity only. We define τt as the mean time between scattering events arising from thermal vibrations alone and as the mean time between scatterings events arising from collisions with impurity alone. In, general an electron may be scattered by both processes, so effective mean time τ between any which scattering events will be less than the individual scattering time.
Determine the amount of heat transfer required to convert 200 g(0.200kg) of ice to vapor if the initial temperature of the ice is25 degrees C and the final temperature is 100 degre

BH curve: For any ferromagnetic material there is a definite value of flux density (B), corresponding to a specified value of magnetising force (H). These values can be ascert
Bending moment : The diagram in created shear forces, but the applied forces also create bending. Consider a section x x' at a distance x measured from end B. Then R B
It is a highly doped p-n junction which is not smashed by high reverse current. The breakdown voltage is made very sharp. In the forward bias, the zener diode do as ordinary diode.
