The spectrum of a black body at two temperatures `27^(@)C` and `327^(@)C` is shown in the figure. Let `A_(1)` and `A_(2)` be the areas under the two curves respectively. Find the value of `(A_(2))/(A_(1))`

The spectra of a black body at temperatures 273^(@)C and 546^(@)C are shown in the figure. If A_(1) and A_(2) be area under the two curves respectively, the value of (A_(2))/(A_(1)) is

The specturm of a black body at two temperatures 27^(@)C and 327^(@)C is show in the Fig. 7(e).20 . Let A_(1) and A_(2) be the respective areas tunder the two curved. Estimate the ratio A_(2)//A_(1) .

If a_(1),a_(2),a_(3) are the last three digits of 17^(256) respectively then the value of a_(2)-a_(1)-a_(3) is equal

In the figure shown the readings of the ammeters A_(1) and A_(2) are respectively.

Let ABC and AB'C be two non-congruent triangles with sides BC=B'C=5, AC=6, and angleA is fixed. If A_(1) and A_(2) are the area of the two triangles ABC and AB'C, then the value of (A_(1)^(2)+A_(2)^(2)-2A_(1)A_(2)cos 2A)/((A_(1)+A_(2))^(2)) is

Let ABC and AB'C be two non-congruent triangles with sides BC=B'C=5, AC=6, and angleA is fixed. If A_(1) and A_(2) are the area of the two triangles ABC and AB'C, then the value of (A_(1)^(2)+A_(2)^(2)-2A_(1)A_(2)cos 2A)/((A_(1)+A_(2))^(2)) is
