<u>Air pressure has no effect at all in an ideal gas approximation. This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature. Sound usually travels more slowly with greater altitude, due to reduced temperature.</u>
The moment of inertia is
Explanation:
The total moment of inertia of the system is the sum of the moment of inertia of the rod + the moment of inertia of the two balls.
The moment of inertia of the rod about its centre is given by
where
M = 24 kg is the mass of the rod
L = 0.96 m is the length of the rod
Substituting,
The moment of inertia of one ball is given by
where
m = 50 kg is the mass of the ball
is the distance of each ball from the axis of rotation
So we have
Therefore, the total moment of inertia of the system is
