Explanation / Answer

Given :

a ) The Mississippi River runs from north to south, whichmeans that mass is being transported to regions where thetangential velocity at the Earth's surface is greater. There are noexternal torques actng on the Earth and so to conserve angularmomentum - the product of the moment of inertia and angularvelocity - a slowing down of the rotation rate must occur.Therefore, the length of the day increases, albeit by anexceedingly small amount!
