Consider the barometer shown in figure. If a small hole is made at a point P in the barometer tube, will the mercury come out from this hole?

Consider the barometer shown in figure. Density of mercury is rho . A small hole is made at point S as shown. The mercury come out from this hole with speed v equal to

Consider a barometer tube filled with mercury as shown in the adjoining figure. If a hole is made at a point Q as shown in the figure, will mercury come out from this hole? Given reasons

Lok at the barometer shown in the figure. If a small hole is developed in the wall of the tube at point A, will the mercvuty leak out of it?

A tank with base area L^2 is filled with a liquid to height H. The tank is acceleration horizontally with acceleration a as shown in figure. If a small hole is made at the point A. then it is observed that the liquid does not come out of the tank. The magnitude of acceleration should be

A small hole is made at the centre of the magnet then its magnetic moment

Consider the diffraction patern for a small pinhole. As the size of the hole is increased

A rectangular tank of height 10m filled with water, is placed near the bottom of a plane inclined at an angle 30^(@) with horizontal. At height h form bottom a small hole is made (as shown in figure) such that the stream coming out from hole, strikes the inclined plane normally.Calculate h.

There are two holes on a water tank as shown in figure. Area of hole 2 is two times that of area of hole 1. Suppose v is the speed of liquid coming out and Q the volume of liquid flowing per second. Then

Two holes are made at a depth of h and 5 h from the water surface in a water container kept on a horizontal surface as shownn in figure. For which value of r, equalt amount of water will come out of the two holes? Here, l is the length of side of the square hole and r is the radius of circular hole.
