If the approximate viscosity of the oil for the following case is `lambda xx 10^(-2) Ns//m^(2)` then find `lambda` :

The cross-section of a bar is given by [1 + (x^(2))/(100)]cm^(2) , where 'x' is the distance from one end. If the extension under a load of '20 kN' on a length of 10 cm is lambda xx 10^(-3) cm then find lambda . Y = 2 xx 10^(5)N//mm^(2) .

If (a - lambda b) . (b - 2c) xx (c + 3a) = 0 then lambda =

A glass plate of length 0.1 m , breadth 15 xx 10^(3) m and thickness 2 xx 10^(-3)m weighs 8 xx 10^(-3) kg in air, it is held vertically with its longer side horizontal and its lower half immersed in water. If the surfaces tension of water is 72 xx 10^(-3) N//m , the apparent weight of the plate is 79.4 lambda xx 10^(-3) N . Then find lambda
