Astronomical observations show that from 1870 to 1900 the length of the day increased by about 6.0 X 10 -3 s. (a) What corresponding fractional change in the Earth's angular velocity resulted? (b) Suppose that the cause of this change was a shift of molten material in the Earth's core. What resulting fractional change in the Earth's rotational inertia could account for the answer to part (a)?
