Show that energy loss from Earths rotational kinetic energy at a rate of 3.9 TW (including dissipation
Question:
Show that energy loss from Earth’s rotational kinetic energy at a rate of 3.9 TW (including dissipation and energy transferred to lunar orbit) corresponds to an increase in length of day of 2.3 ms/century. You may take Earth’s moment of inertia about its rotational axis to be I = 8.0 × 1037 kgm2.
