A river of salty water is flowing with a velocity `2m//sec`. If the density of water is `1.2 gm//c c`, the kinetic energy of each of cubic metre of water is

A river of salty water is flowing with a velocity 2 ms^(-1) If the density of the water is 1.28 c c^(-1) , then the kinetic momentum during a collision, the condition is energy of each cubic meter of water is

A river is flowing with a velocity of 2m/s. If the width of river in 100 m and swimmer wants to cross river is shortest time, what time (in sec) would he take if velocity of swimmer in still water is 4 m/s ?

A river is flowing with a velocity of 2m/s. If the width of river in 100 m and swimmer wants to cross river is shortest time, what time (in sec) would he take if velocity of swimmer in still water is 4 m/s ?

The dissociation of water at 25^@C is 1.9xx 10^(-7) percent and the density of water is 1 gm /cm_3 the ionisation constant of water is :

Water is flowing in a pipe of diameter 4 cm with a velocity 3 m//s . The water then enters into a tube of diameter 2 cm . The velocity of water in the other pipe is

An engine water continuously through a hose. Water leaves the hose with a velocity v and m is the mass per unit length of the kinetic energy is imparted to water ?

A river water is flowing at 5ms^-1 . The depth of river water is 10m. What is the shearing stress between horizontal layers of the river water? Viscosity of water is 1 mili decapoise.
