Define kinematic viscosity.

A steel ball is dropped in a viscous liquid. The distance of the steel ball from the top of the liquid is shown below. The terminal velocity of the ball is closest to

A cubical block of side $a$ and density $\rho$ slides over a fixed inclined plane with constant velocity $v$. There is a thin film of a viscous fluid of thickness $t$ between the plane and the block. Then, the coefficient of viscosity of the thin film will be: (Acceleration due to gravity is $g$)

A cubical block of side $\text{'}a\text{'}$ and density $\text{'}p\text{'}$ slides over a fixed inclined plane with constant velocity $\text{'}v\text{'}.$ There is a thin film of viscous fluid of thickness $\text{'}t\text{'}$ between the plane and the block. Then the coefficient of viscosity of the thin film will be:

Define terminal velocity. Explain the observed rise of air bubbles in a liquid.

If the approximate viscosity of the oil for the following case is $\mathrm{\lambda } \times {10}^{–2} \mathrm{Ns} {\mathrm{m}}^{-2}$ then find $\mathrm{\lambda }$:
