Application +4 | -1

A wooden cube floating in water supports a mass of

m=0.2 {~kg}

on its top. When the mass is removed, the cube rises by

2 {~cm}

. The side of the cube is

\left(\rho_{\text {water }}\right.

=10^3 {~kg} / {m}^3

)

View answer and explanation

Correct option: D

10 {~cm}

The side of the cube is 10 cm. The weight of the mass is equal to the buoyant force due to the submerged volume of the cube. By equating these, the side of the cube can be found.

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
