Answer:
T1 = 250.57[N] and T2 = 250.57[N]
Explanation:
First we have to extract all the information they give us about the problem, then make a free body diagram with all the forces that act on the body.
In the attached image we can see the free body diagram with the respective forces.
By summing up forces on the Y-axis, we can find the T1 and T2 force, these forces are equal since it is an initial condition of the problem. This equation can therefore be cleared.
The equations and analysis can be seen in the attached image

Answer:
a) W=12166.20876 J
b) U= -12166.20876 J
Explanation:
No. of moles, n = 8.41
Change of temperature, ΔT = T1 - T2
= 395 - 279
= 116 K
For monatomic gas, γ = 5/3
γ -1 = 2 /3
Solution:
(a)
Work done,
plugging values we get
Ans: 12166.20876 J
Work done, W = + 12166.20876 J
(b)
From first law of thermodynamics, dQ = U + W
but, dQ = 0 ( adiabatic process)
Hence, U = - W
= - 12166.20876 J
Ans:
Change in internal energy, U = - 12166.20876 J
