What are some common means of restoration and conservation of water resource that we came across in the cases studied so far ?

How can we conserve water ? Write some practices that can be adopted.

What other ways of restoration of a resource does the Kothapally case tell us about ?

Two vessels have the same area but different shapes. The first shapes takes twice the volume of water that the second vessel requires to fill up to a particular common height? Is the force exerted by the water on the base of the vessel the same in the two cases? If so, why do the vessels filled with water to that same height give different readings on a weighing scale?

What does the case tells us about a water resource and its effect on farmers ?

If we want comfort, we must depend on natural resources.So, to conserve natural resources what measures we should follow?

In the pond , we find that different organisms live in different regions. This is due to some conditions like availability of different amount of food, air, light etc. Now let us study the table 4 , showing organisms living in different regions of a pond and answer the question. Name some organisms in the pond that can stay in different regions in the same period? What makes thein stay in different regions in the pond?

Read the given information and answer the following questions. A survey was conducted in two villages, Vanaparthy and Vaddicherla of Warangal district in Telangana State. The first with no scarcity and the second with scarce groundwater. Well census was carried out in the villages in order to get a complete picture of well irrigation and its status as well as availability of water. There are no alternative sources of supply as against wells in Vaddicherla, where there is an existing tank that has been converted into a percolation tank, so that the water situation is much better in Vanaparthy. What are irrigation resources in Telangana State ?

Answer carefully: (a) Two large conducting spheres carrying charges Q_(1) and Q_(2) are brought close to each other. Is the magnitude of electrostatic force between them exactly given by Q_(1),Q_(2)//4pi epsilon_(0)r^(2) , where r is the distance between their centres? (b) If Coulomb’s law involved 1//r^(3) dependence (instead of would Gauss’s law be still true ? (c) A small test charge is released at rest at a point in an electrostatic field configuration. Will it travel along the field line passing through that point? (d) What is the work done by the field of a nucleus in a complete circular orbit of the electron? What if the orbit is elliptical? (e) We know that electric field is discontinuous across the surface of a charged conductor. Is electric potential also discontinuous there? (f) What meaning would you give to the capacitance of a single conductor? (g) Guess a possible reason why water has a much greater dielectric constant (= 80) than say, mica (= 6).
