1.	A uniform metallic disc of radius r and mass m is spinning with angular speed omega_(0) about an axis passing through its centre and perpendicular to plane. If its temperature is increased (slightly) byDeltaT its new angular speed is (The coefficient of linear expansion of the metal is alpha)
Answer» `omega_(0)(1+2alphaDeltaT)` `omega_(0)(1+alphaDeltaT)` `omega_(0)(1-2alphaDeltaT)` `omega_(0)(1-3alphaDeltaT)` ANSWER :C
