relative frequency

Energy Barrier - In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp b (19) where Z is the collision frequency f is the fraction of collisions having energy greater than the threshold energy and p is the fraction of the collisions tha..

The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n .....(1) According to Einstein, mass and energy are related as..

Derivation of de-Broglie Relationship - The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n .....(1) According to Einstein, ..

. The sum of the two sine waves This can be put in a more useful form by using the relation for the sum of two cosines from trigonometry: is the modulation functions or "envelope" (the outer curve in the above figure). In this case, the modulation function happens to be a sine w..

The rainfall patterns in the world are governed by differential heating of air layers over different latitudes. Differential heating of air is the main reason for different convectional air current movement from one part of globe to other. The rainfall is associated with these convectional current..

and d is the distance between the two coherent sources. When a source gives white light, interference fringes are colored. Red fringes are wider as l r is large. Coherent sources are those, which emit continuous light waves of same amplitude, same wavelength/frequency in the same phase or..

. Transition state is supposed to be in equilibrium with the reactants. It also has a very short life. That is why, when it was proposed in the 1930s, it was not possible to study the transition state with the techniques available then. With the help of laser pulses of femtosecond to picoseconds le..

The Biot-Savart law asserts that the magnetic field dB due to an element dl carrying a steady current i at a point P at a distance r from the current element is: The constant m 0 has the exact value m 0 = 4 p x 10 - 7 T m A - 1 It is the permeability of free space. It is ..

>As the armature rotates about an axis perpendicular to the magnetic field, it keeps on changing its relative orientation with respect to the field Thus the flux keeps on changing continuously with time This change in magnetic flux induces an emf If the outer terminals of the armature are..

Summary - With increasing complexity, the organisms have had to develop means of control and coordination between the different parts of the body. Coordination is necessary for acting as one unit and to maintain the homeostasis or steady state within the body. Control and coordination in animals is..
