The PVT behavior of a certain gas is described by the equation of state: P(V − b) = RT where b is a constant. If in addition CV
is constant, show that: (a) U is a function of T only. (b) γ = const. (c) For a mechanically reversible process, P(V − b)γ = const.

Answer:
magnitude of the resultant of forces is 11.45 N
Explanation:
given data
force F1 = 6N
force F2 = 8N
angle = 240°
solution
we get here resultant force that is express as
F(r) = ..............1
put here value and we get
F(r) =
F(r) = 11.45 N
so magnitude of the resultant of forces is 11.45 N

Answer:
The time taken is
Explanation:
From the question we are told that
The value of
The the interior temperature is
The external temperature is
The required interior temperature is
The newton cooling law is
=>
Now integrate both sides we have
Since c is a constant lnC = c will also give a constant so
=>
=>
substituting value
Hence
=>
