what is the origin of viscous drag on a body falling through a fluid?

The viscous drag is

What is the ac celeration of a body falling through a viscous medium after terminal velocity is reached?

The backward viscous force acting on a small spherical body falling through a fluid_______with the increase in velocity of the body.

After terminal velocity is reached the acceleration of a body falling thorugh a viscous fluid is:

Viscous drag force depends on

Two metal ball of radius R and 2 R falling through a fluid have same velocity at some point. The viscous drag acting on them at that instant are in the ratio

Obtain the equation of continuity for the incompressible non - viscous fluid having a steady flow through a pipe.

Assertion : When two boats sails parallel in the same direction and close to each other, they are pulled towards each other. Reason : The viscous drag on a spherical body moving with speed v is proportional to v .

The terminal velocity V of a spherical ball of lead of radius R falling through a viscous liquid varies with R such that

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 A rain drop after falling through a certain distance attains a constant velocity. STATEMENT-2 The viscous force for spherical body is proportional to its speed. Hence after falling through a certain distance viscous drag and buoyant forces balance the gravitational force.
