Let us consider different squares of sides 2, 3, 4 and 5cm, Find the areas of the squares and fill the table. What do you observe? Do you find any change in the area of the square with a change in its side? Further, find the area of a square to the length of its side. Is the ratio same? Obviously not. :. This variation is not a direct proportion

A cube (side =10 cm ) of density 0.5 g//cm^(3) is placed in a vessel of base area 20 cmxx20 cm . A liquid of density 1.0 g/ cm^(2) is gradually filled in the vessel at a constant rate Q=50 cm^(3)//s If we plot a graph between the normal reaction on cube by the vessel versus time. The graph will be like
