Carbon is not used as semiconductor it has 4 valence electrons in it valence shell but the energy gap is very small it will conduct electricity even at room temperature ,the size of carbon is very small .
Answer:
a) 0.39795 kJ/K
b) 79.589.37 kJ
Explanation:
m = Mass of air = 2 kg
Temperature = 200 K
P₁ = Initial pressure = 300 kPa
P₂ = Final pressure = 600 kPa
R = mass-specific gas constant for air = 287.058 J/kgK
a) For isentropic process
∴ Entropy is generated in the process is 0.39795 kJ/K
b)
∴ Amount of lost work is 79.589.37 kJ
Answer:
a)- True
Explanation:
If two statements are inconsistent with each other it means that they are not telling the same, if they are not telling the same it means that only one of them COULD be true, but there is a third option where the two statements are wrong and non statement is telling the true...so:
If we have two statements inconsistent with each other, AT LEAST one of the statements is false.
Answer with Explanation:
Given that
Thus by definition x component of velocity in Lagrangian system is given by
Thus by definition y component of velocity in Lagrangian system is given by
Since in eulerian system we need to eliminate time from the equations
From euations 'i' and 'ii' we can write
Applying these values in the velocity components as obtained in Lagrangian system we get
Answer:
The moment of inertia is basically a physical quantity which describes how easy it is for a body to rotate itself around a given axis.
In easier wording: Moment of Inertia is a body and when it starts rotating or moving, it will keep doing so until we stop it by force.
Explanation:
For example, a car that is moving and active will continue to move even if you were to switch the engine off.
