(fluctuations in the density of a gas) consider an ideal gas of n molecules which is in equilibrium within a container of volume vo. denotes n the number of molecules within any v subvolume of this container. the probability p that a given molecule is within this subvolume v is given by v/vo why? . a) what is the average number n of molecules within v? express your answer based on n, vo and v . b) find the standard deviation (δη)2 in the number of molecules in v (δη)2/n expressing your answer based on n. vo and v then calculate · c)what the response of (b) becomes when y o d) what value should the standard deviation assume according to v - vo? 0

the answer is a)

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
