Due to global warming, if the ice in the polar region melts and some of this water flows to the equatorial region, then

If the moment of inertia of a uniform solid cylinder about the axis of the cylinder is $\frac{1}{n}$ times its moment of inertia about an axis passing through its midpoint and perpendicular to its length, then the ratio of the length and radius of the cylinder is

A body of mass $m$ and radius $r$ rolling horizontally $m$ an inclined plane to a vertical

a velocity $v$ rolls up an height $\frac{v^{2}}{g}$. The body is
