Answer:
B. The same as that for container A
Explanation:
To calculate the average Kinetic Energy per molecule,
Where is the average kinetic energy per molecule and
is the Boltzmann constant
From the above equation it is seen that only depends on the temperature of the gas
And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
Answer:
<em>1.228 x </em><em> mm </em>
<em></em>
Explanation:
diameter of aluminium bar D = 40 mm
diameter of hole d = 30 mm
compressive Load F = 180 kN = 180 x N
modulus of elasticity E = 85 GN/m^2 = 85 x Pa
length of bar L = 600 mm
length of hole = 100 mm
true length of bar = 600 - 100 = 500 mm
area of the bar A = =
= 1256.8 mm^2
area of hole a = =
= 549.85 mm^2
Total contraction of the bar =
total contraction =
==> = <em>1.228 x </em>
<em> mm </em>
