Question

The radius of a circle is 1 cm less than half the side of a square whose area is 256 cm square what is the area of the circle

Answer 1

Molar conductivity of a solution at a given concentration is the conductance of volume V of a solution containing 1 mole of the electrolyte kept between two electrodes with the area of cross-sectionAand distance of unit length. If temp. Increases , k of electrolyte Sol. Increases because mobility of ions increases.
