$A$ box filled with water has a small hole on its side near the bottom. It is dropped from the top of a tower. As it falls,a camera attached on the side of the box records the shape of the water stream coming out of the hole. The resulting video will show
- Athe water coming down forming a parabolic stream
- Bthe water going up forming a parabolic stream
- Cthe water coming out in a straight line
- Dno water coming out

View Solution$A$ large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point $20.0 \ m$ below the water level. If the rate of flow from the hole is $3.08 \times 10^{-5} \ m^3 s^{-1}$, then the diameter of the hole is (Take $g = 10 \ m s^{-2}$): (in $mm$)
Consider the configuration of a stationary water tank of cross-sectional area $A_{0}$ and a small bucket as shown in the figure below. What is the speed $v$ (in $m/s$) of the bucket so that the water leaking out of a hole of cross-sectional area $A$ (as shown) from the water tank does not fall outside the bucket? (Take $h=5 \, m$,$H=5 \, m$,$g=10 \, m/s^{2}$,$A=5 \, cm^{2}$,and $A_{0}=500 \, cm^{2}$).
$A$ light cylindrical vessel is kept on a horizontal surface. The area of the base is $A$. $A$ hole of cross-sectional area $a$ is made just at its bottom side. The minimum coefficient of friction necessary to prevent the vessel from sliding due to the impact force of the emerging liquid is $(a \ll A)$.
