Why do we notice change in bowl 2 through we took milk in both bowls 2 and3 in curd formation?

Why do we add little amount of butter milk to get curd ?

If the point (1, 2, 3) is changed to the point (2, 3, 1) through translation of axes, find the new origin.

Take half glass of water in two beakers or bowls separately. Add 5 to 10 spoons of sugar in the water, and add 2 to 3 spoons of yeast in one of the bowls. Close the bowls with lids and keep them in a warm place. After 3 to 4 hours remove the lids and smell.

Sulphide ion in alkaline solution reacts with solid sulphur to form polysulphide ions having formulae S_2^(2-) , S_3^(2-) , S_4^(2-) and so on. The equilibrium constant for the formation of S_2^(2-) is 12(K_1) and for the formation of S_3^(2-) is 132(K_2) both from S and S^(2-) . What is the equilibrium constant for the formation of S_3^(2-) from S_2^(2-) and S ?

The total revenue in Rupees received from the sale of x units of a product is given by R(x) = 3x^(2) + 36x + 5. Find the marginal revenue, when x = 5, where by marginal revenue we mean the rate of change of total revenue with respect to the number of items sold at an instant.

In deriving Bernoulli's equation, we equated the work done on the fluid in the tube to its change in the potential and kinetic energy. (a) What is the largest average velocity of the blood flow in an artery of diameter 2 times 10^-3 m if the flow must remain laminar? (b) Do the dissipative forces become more important as the fluid velocity increases? Discuss qualitatively?

Consider the lines L _(1) : (x +1)/( 3) = (y+2)/(1) = (z+1)/(2), L_(2): (x-2)/(1) = (y+2)/(2) = (z-3)/(3) The distance of the point (1,1,1) from the plance passing through the point (-1,-2,-1) and whose normal is perpendicular to both the lines L _(1) and L _(2) is
