1 of 1

Application +4 | -1

A small block of wood of specific gravity 0.5 is submerged at a depth of

1.2 \mathrm{~m}

in a vessel filled with water. The vessel is accelerated upwards with an acceleration

a_0=\frac{g}{2}

. Time taken by the block to reach the surface, if it is released with zero initial velocity is

\left(g=10 \mathrm{~m} / \mathrm{s}^2\right)

View answer and explanation

Correct option: B

0.4 \mathrm{~s}

Option A (

0.6 \mathrm{~s}

) is correct because it is the calculated time taken by the block to reach the surface, considering the upward acceleration of the vessel.

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
