Experimentally it was found that a metal oxide has formula M0.98O. Metal M, is present as M2+andM3+ in its oxide. Fraction of the metal which exists as M3+ would be:
The locus of the foot of perpendicular drawn from the centre of the ellipse x2+3y2=6on any tangent to it is
A hoop of radius r and mass m rotating with an angular velocity ω0 is placed on a rough horizontal surface. The initial velocity of the centre of the hoop is zero. What will be the velocity of the centre of the hoop when it ceases to slip?
Based on the data given above, strongest oxidising agent will be:
