The moment of inertia of a thin uniform ring of mass 1 kg and radius 20 cm rotating about the axis passing through the center and perpendicular to the plane of the ring is

Compare closed and open circulatory system.

A thin-ring of radius R metre has charge q coulomb uniformly spread on it . The ring rotates about its axis with a constant frequency of f revolution//s .The value of magnetic induction in omegabm^-2 at the centre of the ring is :

Removal of ring wood of tissue outside the vascular cambium from the tree trunk kills it because:

Who observed that stomata open in light and close in night?

A thin conducting ring of radius R is given a change +Q . The electric field at the centre O of the ring due to the charge on the part AKB of the ring is E. The electric field at the centre due to the charge on the part ACDB of the ring is:

An open pipe is suddenly closed at one end with the result that the frequency of the third harmonic of the closed pipe is found to be higher by 100 Hz than the fundamental frequency of the open pipe. What is the fundamental frequency of the open pipe?
