Catalogs Discussion Forums -> Modern Physics -> what is elastic fatigue? -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

hii

fatigue is caused by repeated cycling of of the load.  It is a progressive localized damage due to fluctuating stresses and strains on the material.   fatigue cracks initiate and propagate in regions where the strain is most severe.   

The process of fatigue consists of three stages:

*  Initial crack initiation
*  Progressive crack growth across the part
*  Final sudden fracture of the remaining cross section       !!!!

hiii
In a nuclear reaction, the total (relativistic) energy is conserved. The "missing" rest mass must therefore reappear as kinetic energy released in the reaction; its source is the nuclear binding energy. Using Einstein's mass-energy equivalence formula E = mc², the amount of energy released can be determined. We first need the energy equivalent of one atomic mass unit:

1 u c2 = (1.66054 × 10-27 kg) × (2.99792 × 108 m/s)2
= 1.49242 × 10-10 kg (m/s)2 = 1.49242 × 10-10 J (Joule)
× (1 MeV / 1.60218 × 10-13 J)
= 931.49 MeV,

so 1 u c2 = 931.49 MeV.

Hence, the energy released is 0.0238 × 931 MeV = 22.4 MeV        !!!!!

Catalogs Discussion Forums -> Physical Chemistry -> what is the difference between collision number and collision frequency -> Go to message
This Post 2 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]

hiiii

collison frequency :-

it is defined as  the average number of collisions between reacting

molecules per unit of time. Its symbol is Z

where


* NA is the number of atoms B per unit volume (m^3)
* σAB is the reaction cross section
* kB is Boltzmann constant
* μaB is the reduced mass of the reactants

 

and collison number is simple a quantity showing algebric numbers .. becoz of

unstable values of this we calculate the frequency !!!!!

Catalogs Discussion Forums -> About IITs and JEE -> plz tell me tips that how can i clear my basics very very very clear means very clear i know if bas -> Go to message
This Post 5 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]

See for clearing ur basics u should have to concenrate on ur studies and read the chapters again and again.Learn the concepts by solving numericals.Imagine the situation given in the numerical and this will help u in making ur fundamentals clear.Learn by heart and keep ur mind open during reading and solving numericals.Numericals are the right way to study the physics. Sometimes the things has to be retain in the mind without thinking on them.So learn how to isolate those facts and try to focus on those fundamentals which can really help u alto in the exam and also valuable.All the best!!!!!

Catalogs Discussion Forums -> Inorganic Chemistry -> for a monoatomic gas the ratio of pressure and volume is always constant which is equal to 2.then Cp -> Go to message
This Post 10 points    (Olaaa!! Perrrfect answer.   in 2 votes )   [?]

hiiiiiiii

degree of freedom = 3 for monoatomic gas

and Cv   =   (f/2)R

   and    Cp  - Cv   =  R

where f is degree of freedom

then   Cv   =   (3/2 )  R

              Cp  =  (5/2) R   !!!!!

Catalogs Discussion Forums -> AIIMS -> how would i start the test -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
First u should try to find out in which subject u have command try it first and then allow urself a minute to think about the question and then answer it.Secondly if u find that u are not able to answer some of the question then leave it and then again go through it after completing the paper and then start thinking again about this.Thirdly, do not loose ur confidence if stuck somewhere between the question.Do paper with full concentration.Be cool and relax for ur exam..All the best!!!!

Viruses are the organisms which consists of nucleic acid and a protein.nucleic acid and protein are the infectious agent in the virus while priona are the proteincous particle which is destabilize thenormal protein structure.Prions causes the deposition of amyloid in the cells.These prions causes many neurodegenerative disesae by acusing deposition of amyloid particles in the CNS.these disease include scrapie, bovine spongiform encephalopathy,etc

Question banks from brilliant tutorials are perfect and worth doing.They are enough to revise the whole subjects in last minutes..Alen's is also good but they are more descriptive an d u cannot do it on last minute..So, go for Brilliant tutorials.

It states that for all liquids the entropy of vapourization is same i.e 87–88 J K−1 mol−1.Entropy of vapourization is the ratio of enthalpy of vapourization to the temperature.But this rule is not universal as there are many exceptions to this rule like water, ethanol do not meet the criteria of the law.But some follows it like benzene and choloroform.
