A small steel ball of mass m and radius r is falling under gravity through a viscous liquid of coefficient of viscosity eta . If g is the value of acceleration due to gravity. Then the terminal velocity of the ball is proportional to (ignore buoyancy)

In dimension of critical velocity v_(c) liquid following through a take are expressed as (eta^(x) rho^(y) r^(z)) where eta, rhoand r are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively then the value of x,y and z are given by

Using dimensions show that the viscous force acting on a glass sphere falling through a highly viscous liquid of coefficient of viscosity eta is Fprop eta av where a is the radius of the sphere and v its terminal velocity.

If force F is applied on a body and it moves with a velocity v, the power 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:
