Explain the term 'work function' of a metal. The threshold frequency of a metal is f0. When the light of frequency 2f0 is incident on the metal plate, the maximum velocity of electrons emitted is v1. When the frequency of the incident radiation is enhanced to 5f0, the maximum velocity of electrons emitted is v2. Find the ratio of v1 to v2.
It determines the probability of an electron occupying a state at an energy level E. This takes into account that a collection of electron must obey the Pauli Exclusion Principle.

1. Cell growth. if V is the volume of a spherical cell, then, in certain cell growth or for some fetal growth models, the rate of change of V is given by dV/dt =kV2/3, where k
Has Vc a limit? Answer; precisely, but we do not know its limit. But we know it is greater than c.
