A sphere of coefficient of linear expansion alpha, mass 'm' and radius

1.	A sphere of coefficient of linear expansion alpha, mass 'm' and radius 'r' is is spinning about an axis through its diameter with an angular velocity 'omega' when it is heated such that its temperature increases by Deltat, the angular velocity becomes
Answer» `OMEGA ( 1+ DELTA t)^(2)` `( omega)/( ( 1+ 2 alpha Delta t))` `omega ( 1+ alpha Delta t)` `omega alpha Delta t` Answer :B
