List of top Physics Questions on mechanical properties of fluid asked in NEET (UG)

If a soap bubble expands, the pressure inside the bubble:

A spherical ball is dropped in a long column of a highly viscous liquid. The curve in the graph shown, which represents the speed of the ball (v) as a function of time (t) is:

The velocity of a small ball of mass M and density d, when dropped in a container filled with glycerine becomes constant after some time. If the density of glycerine is \(\frac{d}{2}\), then the viscous force acting on the ball will be

A small hole of area of cross-section $2 \,mm^2$ is present near the bottom of a fully filled open tank of height $2 \,m$. Taking $g = 10 \,m/s^{-2}$. the rate of flow of water through the open hole would be nearly:

A soap bubble, having radius of $1 mm$, is blown from a detergent solution having a surface tension of $2.5 \times 10^{-2} N / m$. The pressure inside the bubble equals at a point $Z _{0}$ below the free surface of water in a container. Taking $g = 1 0 m / s ^{2}$, density of water $= 1 0 ^{3} kg / m ^{3}$, the value of $Z _{0}$ is:

A rectangular film of liquid is extended from $(4 \, cm \times 2\, cm)$ to $ (5 \, cm \times 4 \, cm)$. If the work done is $3 \times 10^{-4} \, J$, the value of the surface tension of the liquid is -
