Three liquids of equal masses are taken in three identical cubical vessels A ,B and C . Their densities are respectively but . below the force extract by the liquid on the base of cubical vessel is
View answer and explanation
Correct option: C
the same in all the vessels
Option C (the same in all the vessels) is correct because the force exerted by a liquid on the base of a vessel depends only on the height of the liquid column and the area of the base, and since the masses are equal and the vessels are identical, the height will adjust such that the force is the same.

With the increase in temperature viscosity of a liquid -
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.
Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
on As the temperature of a liquid is raised, the coefficient of viscosity A horizontal pipe of cross-sectional diameter 5 cm carries water at velocity of . The pipe is connected to a smaller pipe with a cross-sectional diameter 4 cm. the velocity of water through the smaller pipe is If two soap bubble of different radii are connected by a tube
