$A$ wire has a resistance of $12 \, \Omega$. It is bent in the form of an equilateral triangle. The effective resistance between any two corners of the triangle is:

If a solid sphere is rolling,the ratio of its rotational kinetic energy to the total kinetic energy is given by:

Statins, used as blood cholesterol-lowering agents, are extracted from:

If $3 \cos x \neq 2 \sin x$,then the general solution of $\sin^2 x - \cos 2x = 2 - \sin 2x$ is
