Value of Water in Life Water is one of the things we need most besides air. Thank God water is plenty because three-fourths of earth's surface is covered with water. This is only a general fact and not all places on earth are having enough water Healthy potable water is a rare commodity. Rivers may bring water and lakes may be a rare commodity. Rivers may bring water and lakes may be having it. From the health viewpoint, they may not be fit for drinking. Most of these waters are contaminated and may contain mineral as well as organic Impurities. Sometimes epidemic spreading bacteria like those causing cholera and typhoid victimize us. Nowadays the chances of contamination of water sources are quite common with industries coming up and sending out their effluents indiscriminately. So to make these waters portable, they must be treated before being supplied to the public.               Treating water and supplying it to a town or city adds cost. The water has to be filtered f

1)A simple harmonic wave of amplitude 8 units traverses a line of particles in the direction of the positive x-axis. At any given instant of time, for a particle at a distance of 10 cm from the origin, the displacement is 6 units, and for o particle at a distance of 25cm from the origin, the displacement is 4 units calculate the wavelength. Ans: 2) Define wave Does the particles of the medium travel from one place to another place while propagation of wave? Explain with example. What ore the types of wave explains with their properties? Ans: 3) 4) 5) 6) 7) 8) 9)
