a rain drop falls from rest in an atmosphere saturated with water vapour. As it falls, water vapour condenses on drop at rate of mass µ per second. If initial mass of drop is M0, how much distance the drop falls in time t?

a thin rod of length 2R and mass M is standing vertically on a perfectly smooth floor. the state of equilibrium in which the rod at rest is unstable and the rod falls. FInd the trajectories that the various points of rod describe and velocity with which t...

1. calculate H+ ion concentrates in 0.10 m acetic acid solutions. Given that dissociation constant of acetic acid in water is 1.8 * 10^-5 ? 2. Calculate the concentration of H+ and OH- in a 0.05 m HNO3 solutions at 25^0c ? 3. The degree of dissociation of...

The Young's modulus for steel is 2x1011 and its rigidity modulus is 8x1010 Nm-2. Find the Poisson's ratio and its bulk modulus.

A body of mass M1 collides elastically with another body of mass M2 at rest. After collision the velocity of M1becomes ¾ times of the velocity. Find the ratio of their masses
