A

10 cm

B

11.7 cm

C

7.5 cm

A vessel having perfectly reflecting plane botton is filled with water (mu=4//3) to depth d. A point source of light is placed at a height h above the surface of water. Find the distance of final image from water surface.

A mark is made on the bottom of a vessel and over this mark, a glass slab to thickness 3.5 cm and refractive index (7)/(4) is placed. Now water (refractive inidex, (4)/(3)) is poured into the vessel so that the surface of water is 8 cm above the upper surface of the slab. Looking down of normally through the water, the apparent depth of the mark below the surface of water will be :

An inverted cone has a depth of 10cm and a base of radius 5cm. Water is poured into it at the rate of 3/2 c.c.per minute.Find the rate at which the level of water in the cone is rising when the depth is 4cm.

The figure shows the commonly observed decrease in diameter of a water stream as it falls from a tap. The tap has internal diameter D_(0) and is connected toa large tank of water. The surface of the water is at a height b above the end of the tap. By considering the dynamics of a thin "cylinder" of water in the steam answer the following: (ignore any reistance to the flow and any effects of surface tansion, given rho_(w) = density of water) A student observes after setting up this experiment that for a tap with D_(0) = 1 cm at x = 0.3 m the stream diameter D = 0.9 cm . The heights b of the water above the tap in this case will be:

Water leaks out from an open tank through a hole of area 2mm^2 in the bottom. Suppose water is filled up to a height of 80 cm and the area of cross section of the tankis 0.4 m^2 . The pressure at the open surface and the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank. a. Find the initial speed of water coming out of the hole. b. Findteh speed of water coming out when half of water has leaked out. c. Find the volume of water leaked out during a time interval dt after the height remained is h. Thus find the decrease in height dh in term of h and dt. d. From the result of part c. find the time required for half of the water to leak out.
