A sphere made of iron is rotating about its diameter as axis `alpha=1xx10^(-5).^(@)C^(-1)`. If the temperature rises by `100^(@)C` the percentage increase in its moment of inertia is:

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 ).

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 )

The diameter of a fly wheel is R . Its coefficient of linear expansion is alpha . If its temperature is increased by deltaT the percentage increase in its moment of inertia is

A circular disc made of iron is rotated about its axis. If due to the change of surrounding temperature its angular speed increased by 1%, then find the percentage change in its kinetic energy

The moment of inertia of a rod about its perpendicular bisector is I . When the temperature of the rod is increased by Delta T , the increase in the moment of inertia of the rod about the same axis is (Here , alpha is the coefficient of linear expansion of the rod )
