Answer:
Explanation:
The rank of the magnitude of the diffusion coefficient from greatest to least is as follows:
C in Fe at 900°C > Cr in Fe at 900°C > Cr in Fe at 600°C
Reason
C in Fe is an interstitial impurity while Cr in Fe is a substutional impurity.Therefore interstitial impurity occurs in C in Fe systems,while substutitional diffusion occurs in Cr in Fe system.Interstitial is much faster than substitutional diffusion hence the order
Also with increasing temperature magnitude of diffusion coefficient increases,due to the relation.
D = D₀exp(-Qd/RT)
Where D₀=Temperature independent per exponential
Qd= The activation energy for diffusion
R= Universal gas constant
T=absolute temperature
Answer:

Explanation:
We apply Hooke's Law as follows :

where
is the applied stress
#The applied stress is also equal to :

Where
and
are the cross-sectional dimensions.
=>We equate the two stress equations:

#We substitute our values in the equation as:

Hence, the resulting strain is 0.00151

If you are asking what is heavier fisicly it would be a ton of bricks
but if your talking emotionaly I think it would be death
