engineering approach their work by finding new solutions to their problems. like if two things dont go together in an invention, they will find another way
'Capturing a photon by<em> isomerization and rhodopsin </em>of retinal' is the first step necessary for initiating the visual transduction cascade in rods.
Visual transduction refers to the process in the eye where absorption of light in the 'retina' is translated into electrical signals that then reach the brain. It is correct to state that visual transduction is the photochemical reaction that takes place when light or photon is converted to an electric signal in the retina. The visual pigment in the rods, called rhodopsin, is a membrane protein placed in the outer segments of the rods.
When initiating the visual transduction cascade in rods the first vital step is to capture a photon by<em> isomerization and rhodopsin</em> of retinal'.

Answer:
t=5.5 mm
Heat dissipation per unit length = 90.477 W/m
Explanation:
Given that
Diameter d = 5 mm ⇒r = 2.5 mm
Conductivity of insulated material K = 0.16 W/mK
Heat transfer coefficient = 20 
When thickness reaches up to critical radius of insulation then heat dissipation will be maximum
We know that critical radius of insulation of wire is given as follow
Now by putting the values
So the thickness of insulation
t=8-2.5 mm
t=5.5 mm
As we know that heat transfer due to convection given as follows
Q = hAΔ T
Q=20 x 2 x π x 0.008 x (120-30)
Q = 90.477 W/m
So heat dissipation per unit length = 90.477 W/m
Is 4/8 bigger than 8/12 ? no
because 4/8 is 1/2 and 8/12 is more than a 1/2
