Torques of equal magnitude are applied to a thin hollow cylinder and a solid sphere, both having the same mass and radius. Both of them are free to rotate about their axis of symmetry. If alpha_(c) and alpha_(s) are the angular accelerations of the cylinder and the sphere respectively, then the ratio (alpha_(c))/(alpha_(s)) will be

If alpha_(c) and alpha_(f) denote the numerical values of coefficient of linear expansion of a solid, expressed per .^(0)C and per .^(0)F respectively, then

if alpha_(c) and alpha_(f) denote the numerical values of coefficient of linear expansions of the solid, expressed per ^(0)C and per Kelvin respectibely, then.

If |(a,b,a alpha+b),(b,c, b alpha+c),(a alpha+b, b alpha+c,0)|=0 then

If |{:(a,b,a alpha+b),(b,c,b alpha+c),(a alpha +b,b alpha+c,0):}|=0 Prove that a,b,c are in G.P. or alpha is a root of ax^2 + 2bx + c=0
