Within the exponential phase of growth , if the initial surface area and the growth rate of a leaf are `10 mm^(2)` and `0.015 mm^(2)`/hour respectively , the area of the leaf after 4 days would range from :

In the figure shown below, a source of sound having power 12xx10^-6W is kept at O , which is emitting sound waves in the directions as shown. Two surfaces are labelled as 1 and 2 having areas A_1=2xx10^3m^2 and A_2=4xx10^3m^2 , respectively Q. Let the areas of the eardrums of persons A and B be A_A=2mm^2 and A_B=4mm^2 , respectively. Then who will hear a quiter sound?
