[Any unit of mass] divided by [any unit of volume]
is a perfectly good unit of density.
Probably the most widely used unit is (gram / cubic centimeter).
But it could just as well be (metric tonne / cubic parsec) .
Answer:
t= 1.2 hours
Explanation:
Define first di distance between the points, so
The distance is
To find the internal energy of gas we can use
here given that
Number of moles (n) = 7 moles
Temperature T = 40 + 273 = 313 K
degree of freedom(f) = 5 (for diatomic gas)
now by above formula
<em>So it is approximately 45500 J (option C)</em>
