A spherical ball is dropped in a long column of a viscous liquid. The speed v of ball as a function of time may be best represented by graph
Find ratio of terminal velocity.
If n identical water droplets falling under gravity with terminal velocity v coalesce to form a single drop which has the terminal velocity 4v, find the number n.
White light is incident on a soap film of refractive index 34 at an angle of refractive 30o. The transmitted light is observed to have a dark band for wavelength 6×10−5cm. Calculate the minimum thickness of the film.
A water drop of radius 1.5 mm is falling from height 1 km having drag constant 0.5 density of water drop is 1000 kg/m3 and density of air is 1.29 kg/m3. Find the terminal velocity.
The diagram shows a cup of tea seen from above. The tea has been stirred and is now rotating without turbulence. A graph showing the speed v with which the liquid is crossing points at a distance X from 0 along a radius XO would look like
The force of viscosity is:
Rain drops, each of radius r, are falling through air with steady velocity v. If eight drops coalesce to form a big drop, then the big drop so formed will fall with velocity ?
