So, if the moment of inertia increases by 0.2 parts per million, the angular
velocity must decrease by the same amount to keep the angular momentum
constant. If this unfortunate occurrence happened in the current day, length
of day would thus increase by 0.017 SI-seconds.
Um, I said if this unfortunate occurrence happened in the current day. It is
