Mechanical Properties Of Fluids
Two blocks A and B float in water. If block A floats with 41 th of its volume immersed and block B floats with 53 th of its volume immersed, the ratio of their densities is
A lead shot of 1 mm diameter falls through a long column of glycerine. The variation of the velocity with distance covered (s) is correctly represented by
A square plate of 0.1 metre side moves parallel to a second plate with a velocity of 0.1 m/s,both plates being immersed in water. If the viscous force is 0.002 newton and the coefficient of viscosity is 0.01 poise,distance between the plates in metre is:
A small metal ball of mass 'm' is dropped in a liquid contained in a vessel, attains a terminal velocity 'V'. If a metal ball of same material but of mass ′8m′ is dropped in same liquid then the terminal velocity will be.
If the terminal speed of a sphere of gold (density =19.5kg/m3) is 0.2m/s in a viscous liquid (density =1.5kg/m3), find the terminal speed of a sphere of silver (density =10.5kg/m3) of the same size in the same liquid
An Indian Submarine is moving in "Arab Sager" with a constant velocity, detect enemy it sends out sonar waves which travel with velocity 1050 m/s in water. Initially, the waves are getting reflected from a fixed land the reflected waves are coming back to the submarine. The frequency of reflected waves are detected by & submarine and found to be 10% greater than the sent waves.
Now an enemy ship comes in front. due to which at type frequency of reflected waves detected by submarine becomes 21% greater than the sent waves.
An oil drop falls through air with a terminal velocity of 5×10−4m/s. The radius of the drop will be? Neglect density of air as compared to that of oil.
