Statement I: A ship floats higher in water on a high
pressure day than on a low pressure day.
Statement II: Floating of ship in the water is possible
because of the buoyant force which is present due to the
pressure difference.
pressure day than on a low pressure day.
Statement II: Floating of ship in the water is possible
because of the buoyant force which is present due to the
pressure difference.
View answer and explanation
Correct option: D
Statement I is false; Statement II is true
Option D (Statement I is false; Statement II is true) is correct. A ship floats due to buoyant force, which is related to pressure difference, but atmospheric pressure has a negligible effect on how high a ship floats.

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
