Text Solution

The days will become shorter.The kinetic energy of rotation about its own axis will decreaseThe duration of the year will increaseThe magnitude of angular momentum about its axis will increase.

Answer :

ASolution :

`I_(1)omega_(1)=I_(2)omega_(2)` (Angular momentum is conserved) <br> As `I_(2)` decreases `omega_(2)` increases. <br> Thus `T=(2pi)/(omega)` i.e. `T` decreases <br> Therefore the earth is completing each circle around its own axis in lesser time. <br> `K.E.=1/2Iomega^(2)` Therefore `K.E.` of rotation increases. <br> Duration of the year is dependent upon time taken to complete one revolution around the sun.
