Poiseuille's equation holds good when

What is the main difference in the applicatoin of Poiseuille's equation and Stokes' law?

Write down Poiseuille's equation in terms of velocity of flow of liquid.

State whether the following statements are True (T) or False (F): In case of spherical mirror the mirror equation holds good when the aperture of the mirror is small.

The rate of flow (V) of a liquid flowing through a pipe of radius r and pressure gradient (P//I) is given by Poiseuille's equation V = (pi)/(8)(Pr^4)/(etaI) Chack the dimensional correctness of this relation.

For the Boyle's law to hold good, the necessary condition is

Snell's law of refraction does not hold good when the angle of incidence on a refracting surface is

The Coulomb's law holds good when distance (r ) between the two point changes is

When an electric cell is in use, .... Relation holds good.
