The concept that must be applied to solve this problem is that of the magnetic field on Toroid described since the law of Ampere. Mathematically the magnetic field is determined as
Where
= Permeability constant
N = Number of loops
I = Current
r = Radius
As we can see the magnetic field inside a Toroid is NOT uniform, since it is highly proportional to the radius. Which means that as the radius increases the magnetic field decreases.
Therefore the correct answer is: FALSE
Answer:
a)
b)
c)
d)
e)
Explanation:
a) Let's recall the definition of work.
Because the system is a quasi-static isobaric expansion, P is constant here, therefore:
b) Using the ideal gas equation we have:
(1)
and (2)
We can note that n times R is a constant in (1) and (2), so we can equal those equations.
(3)
Let's solve T₂ for (3), let's recall that P₁ = P₂, so they canceled out
c) Using the equation of ideal gas we have:
d) We can write the internal energy as a function of Cv, and as we know the Cv is 1.5R for a monoatomic gas.
e) Using the first law of thermodynamic, we have:
Finally,
Have a nice day!
