Answer:
Implements a reordering of the letters of the alphabet.
Explanation: GIVE ME 5 STARS AND a HEART!!! Those contacts are wired across the rotor so that each contact on the left connects to the contact on the right in some scrambled arrangement. Each rotor, therefore, implements a reordering of the letters of the alphabet, which mathematicians call a permutation.
Answer:
a)True
Explanation:
According to Fourier's law,It states that Heat transfer is directly proportionate to the temperature gradient.For unidirectional conduction
![q''\alpha\dfrac{dT}{dx}](https://tex.z-dn.net/?f=q%27%27%5Calpha%5Cdfrac%7BdT%7D%7Bdx%7D)
Where q'' is the heat flux.
When This directly proportionate is remove then one constant will on that place and that constant is called conductivity of material.
![q''=K\dfrac{dT}{dx}](https://tex.z-dn.net/?f=q%27%27%3DK%5Cdfrac%7BdT%7D%7Bdx%7D)
So total heat transfer Q
![Q=KA\dfrac{dT}{dx}](https://tex.z-dn.net/?f=Q%3DKA%5Cdfrac%7BdT%7D%7Bdx%7D)
When conductivity (K) of material is not constant
K=
(a+bT) where a,b are constant.
So from the above expression we can say that heat transfer in material will depend on temperature difference,material property and on on geometry of object.
