1. A protein was observed to move 300 µm in 12.7 minutes at 23°C. Assuming its density and viscosity to be 1.34 g/cm3 and 0.89 X 10-2 g/cm s respectively, calculate the following parameters related to the protein's shape and its movement.
a. Diffusion coefficient
b. Friction coefficient
c. Radius
d. Volume
e. Molar weight
Viscosity in fluids is the analog of friction in solids. Both are methods by which the kinetic energy of moving bodies can be changed into thermal power. In the absence of friction
It is the degree or extent by which magnetic lines of force can enter a substance and is expressed by µ.
If two soap bubbles of different radii are connected by a tube then, what happen? Ans) When these bubbles are joined through tube..the smaller bubble(with more pressure) gets its
Brownian motion (R. Brown; 1827) It is the continuous random motion of solid microscopic particles while suspended in a fluid medium because of the consequence of ongoing bomb

A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 60 km/h?
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
The overall length of a particular wind instrument is 35.0 cm. The resonating air column vibrates as ina pipe that is open at both ends. (a) Find the frequency of the lowest not
