 PLEASE TAKE YOUR TIME ANSWERING, LAST EXPERT DID NOT ANSWER THE PROBLEM CORRECTLY.

As shown in the image, the axis of Earth makes a 23.5∘ angle with a direction perpendicular to the plane of Earth’s orbit. This axis precesses, making one complete rotation in 25,780 years. The Earth has a mass of 5.972×1024kg and a radius of 6.378×10^6m.

a. Calculate the spin angular momentum of the Earth in units of kilogram meter squared per second. 

b. Calculate the magnitude of the change in angular momentum in units of kilogram meter squared per second in half this time. 

c. What is the average torque producing this change in angular momentum?
