Assertion: Sometimes insects can walk on water.
Reason: The gravitational force on insect is balanced by force due to surface tension.
Reason: The gravitational force on insect is balanced by force due to surface tension.
View answer and explanation
Correct option: A
If both Assertion and Reason are true and Reason is the correct explanation of Assertion
Option A is correct because the insect's ability to walk on water is due to surface tension, which balances the gravitational force acting on it.

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
