A uniform solid brass sphere is rotating with angular speed `omega_0` about a diameter. If its temperature is now increased by `100^@C`, what will be its new angular speed. (given`alpha_B=2.0xx10^-5per^@C`)

A metal solid sphere is rotating about an axis passing through its diameter, if its volume increased by 6% suddenly then its change in angular speed will be………

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) by DeltaT its new angular speed is (The coefficient of linear expansion of the metal is alpha )

A solid cylinder of mass M and radius R rotates about its axis with angular speed omega . Its rotational kinetic energy is

A solid cylinder of mass M and radius R rotates about its axis with angular speed omega . Its rotational kinetic energy is

A metallic solid sphere is rotating about its diameter as axes of rotation. If the temperature is increased by 200^(@)C , the percentage increase in its moment of inertia is (Coefficient of linear expansion of the metal =10^(-5)//""^(@)C )

In previous problem, if initially the platform with the child is rotating with an angular speed omega_(1) . If child start walking along its periphery in opposite direction with speed u relative to platform, what will be the new angular speed ofthe platform.

A metallic solid sphere is rotating about its diameter as axis of rotation. If the temperature is increased by 200^(@)C the percentage increase in its moment of inertia is (Coefficient of linear expansion of the metal = 10^(-5)//^(@)C ).
