Answer 4

:P

Answer 5

@shubhamsrg i read this but kuch smajh nhi aaya sb sr k upar se gya :(

Answer 6

relaxation time for a system is the time it takes for the system to return to equilibrium after an impulse

Answer 7

now i got the difference thank u @UnkleRhaukus :)

Answer 8

@Vincent-Lyon.Fr do u have any better answer???

Answer 9

Yaar examples lai lo na

Jaisa kai collision time samajh nai kai liye ye sawal lailo

How does it make a diff when a biker wears and helmet.

Daikho Jab biker girta hai na tau helmet mai aik sponge hota hai jo kai time barha deta hai jiss sai collision time barh jata hai samjhe.

A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time.

Collision aik event hai jissme dau ya us sai ziada body collide krti hai ya phir wo aik dusre par force exert karti hai aik relatively short time kai liyee

Answer 10

@hba actually i meant for collision time and relaxation time of electrons in a conductor or semiconductor or insulator.............so u r correct i know this but this is not what i want ;)

Answer 11

Are yaar kasme phele bolte na.

Answer 12

Merai paas aik video thi iss kai liyee mil nahee rahi :/

Answer 13

ohhhh
to jldi se dhundo ya related link bhejo bhaiya vrna dikkat ho jayegi hmko.........kl MDU ka exam hai :(

Answer 14

Answer 15

koi nhi mile to de dena kya pta kb zaroorat pd jaye
pr dimag ki maa bhen ho rkhi hai papero ki vjah se :(

Answer 16

Haha,Chill maaro ziada fikar nahe kro :)

Answer 17

Relaxation time is the typical time it takes a system to adapt to a change in the conditions applied to it. Usually derived from a first order differential equation.

Collision time is defined in microscopic models as the average time between two collisions undergone by a particle "followed in your mind" (I do not know how this is said in English).

In models of conduction such as Drude's model, these times are identical, by I'm sure the reference suggested by shubhamsrg sheds new insight on the matter.

Answer 18

*other wording:
Relaxation time is the time taken by a system to reach a new equilibrium or steady state under new conditions.

Answer 19

thanks @Vincent-Lyon.Fr can u help in one more
derivation of relation between collision time, mean free path and relaxation time
plz

Answer 20

Sorry, I am no expert on the subject. I might give a derivation that would prove wrong according to the reference above.

Answer 21

hehehe......no problem and thanks a lot 4 ur help :)
