A lead sphere acquires a terminal velocity upsilon when falls in a vicous liquid. The terminal velocity attained by another lead sphere of radius three times in the same liquid will be _______

When a sphere falling in a viscous fluid attains a terminal velocity, then

A sphere of mass M and radius R is falling in a viscous fluid. The terminal velocity attained by the falling object will be alphaortional to :

A solid sphere falls with a terminal velocity v in air, if it is allowed to fall in vacuum. Its terminal speed

A steel ball of mass m falls in a viscous liquid with terminal velocity v, then the steel ball of mass 8m will fall in the same liquid with terminal velocity

A sphere of radius R and density rho_1 is dropped in a liquid of density sigma . Its terminal velocity is v_1 . If another sphere of radius R and density rho_2 is dropped in the same liquid, its terminal velocity will be:

A solid sphere, of radius R acquires a terminal velocity v_1 when falling (due to gravity) through a viscous fluid having a coefficient of viscosity eta he sphere is broken into 27 identical solid spheres. If each of these spheres acquires a terminal velocity v _2 when falling through the same fluid, the ratio (v_1//v_2 ) equals:

The terminal velocity of a sphere moving through a viscous medium is :

A solid sphere falls with a terminal velocity v in air .If it is allowed to fall in vaccum,

A small sphere of volume V falling in a viscous fluid acquires a terminal velocity v_t . The terminal velocity of a sphere of volume 8V of the same material and falling in the same fluid will be :
