A satellite that is a spinning cylinder has initial rotational inertia I\textsubscript{0}~and angular velocity w\textsubscript{0.~}Solar panels unfold from the satellite and are extended outward. The satellite then has rotational inertia I\textsubscript{f} = al\textsubscript{0} and angular velocity w\textsubscript{f} = bw\textsubscript{0,~}where a and b are constants. Which of the following is true about the constants a and b ? 
选项为:A:a = l and b = 1  B:a \textgreater{} 1 and b \textless{} l  C:a \textgreater{} l and b = 1  D:a \textless{} l and b \textless{} l  请回答其中一个选项.
