Stress, in physical sciences and engineering, force per unit area within materials that arises from externally applied forces, uneven heating, or permanent deformation and that permits an accurate description and prediction of elastic, plastic, and fluid behaviour.

hope i could help
Explanation:
Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.
So by using the equation of diffraction,
dsinA = nL
SinA is a geometric component it can be written as,

∵ x is the distance from screen.
∵ y is the half of the width of central maximum.
now by putting the values in mm,

d = 2.15×
mm
Answer:
Explanation:
Given
Temperature of Hot reservoir 
Temperature of Cold reservoir 
Heat reservoir 
Work done 
heat Exhaust 


L.H.S=R.H.S
thus it follows first law



Cycle Efficiency

Carnot efficiency is less than cycle thus it violates second law
D. 5.098 x 106 is the correct answer when reduced to the proper notation.
