PHXI11:THERMAL PROPERTIES OF MATTER

366698 A uniform solid brass sphere of radius \(a_{0}\) and mass \(m\) set spinning with angular speed \(\omega_{0}\) about a diameter at temperature \(T_{0}\). If its temperature be increased to \(T\) without disturbing the sphere, its new angular velocity \(\omega\) will be assuming that its new radius is \(a\) :

1 \(\omega=\omega_{0}\)
2 \(\omega=\dfrac{T}{T_{0}} \omega_{0}\)
3 \(\omega=\left(\dfrac{a_{0}}{a}\right)^{2} \omega_{0}\)
4 \(\omega=\left(\dfrac{T-T_{0}}{T_{0}}\right) \omega_{0}\)
