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.
Is the common end is important? Even though manufacturers place extra attention on fibers and illuminators the common end is a very important piece for the correct operation of
Q What is Seebeck effect? Seebeck revealed that in a circuit consisting of two dissimilar metals like iron and copper an emf is developed when the junctions are maintained at
As a longitudinal wave moves through a medium, the particles of the medium: a) vibrate in a path parallel to the path of the wave b) vibrate in a path perpendicular to the p
a sphere is at rest on a wall at a angle of 3,4(slpoe) to the left. it also rest against a vertical wall. we are to find the magnitude of the resultant force at the vertical wall.
how to make a ray diagram ?? and what are f, p ?? and what is refraction index?????
LENARD ATOMIC MODEL : Lenard suggested that the atom must have a lot of empty in it. Lenard's model of an atom could not explain about the stability and mass of an atom .
the velocity of a particle moving along x axis is defined by v=kx^3-4x^2+6x where v is in m/s,x in m and k is a constant .if k=2 compute the acceleration when x=2m
NEWTON'S FIRST LAW AND INERTIA: All the material bodies possess the property of opposing any alter in the state of rest or uniform motion when some external force is applies up
By what factor would the I 2 R loss in transmission wires be reduced if the transmission voltage were boosted from 220 V to 22 kV? Suppose that the rate of energy delivered is
