Efflux is coming out of hole as shown in figure

A disc is hanging from pin hole as shown in figure and displaced slightly, then its time period.

A small hole P is made in a piece of cardboard. The hole is illuminated by a torch as shown in Fig. 16.3. The pencil of light coming out of the hole falls on a mirror. At which point should the eye be placed so that the hole can be seen?

Consider the combination of resistors as shown in figure and pick out the correct statement

Water is coming out of a hole made in the wall of a fresh water tank . If the size of he hole is increasesd, (i) will velocity of efflux of water change? (ii) will the volume of the water coming out per second change?

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

Two immiscible liquids of densities d and 2d are taken in a cylindrical vessel with equal heights each h. The velocity efflux of the liquid coming out of the hole made to the wall of the vessel at its bottom is

An open vessel full of water is falling freely under gravity. There is a small hole in one face of the vessel, was shown in te figure. The water which comes out from the hole at the instant when hole is at height H above the ground strikes the ground at a distance of x from P. Which of the followin is correct for the situation described? (a). The value of x is 2sqrt((2hH)/(3)) (b). The value of x is sqrt((4hH)/(3)) (c). The value ofx can't be computed from information providec. (d). The question is irrevalent as no water comes out from the hole.

Find out the velocity of block E as shown in figure.

A liquid of density rho is filled in a vessel up to height H and a hole of cross section area A is made at a depth h below the free surface of liquid. The speed of liquid coming out of the hole is independent of
