Answer:
they cross over one another between charge.
Answer:
The correct option is propped cantilever beam.
Explanation:
A propped cantilever beam along with all the reactions is shown in the attached figure.
Since we can see that the number of unknowns are 4 but the equations of statics are only 3 thus we conclude that the beam is indeterminate to 1 degree.
For all the other beams the reactions and the equations are 3 each thus making the system determinate.
To solve the problem it is necessary to refer to the definition of entropy.
Entropy is defined aso
Where,
Heat exchange
T = Temperature
Since the heat exchange is conserved and it is an isothermal process where the temperature remains constant the change in entropy remains the same, ie 
(Reamins same)
Therefore the correct answer is C.
n₂ = index of refraction of glass = 1.58
n₁ = index of refraction of air = 1
θ = Brewster's angle
Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.
Brewster's angle is given as
θ = tan⁻¹(n₂ /n₁ )
θ = tan⁻¹(1.58/1 )
θ = 57.7 deg
hence the Brewster's angle comes out to be 57.7 deg
