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 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 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 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.

A regular pentagons is inscribed in a circle. If A_(1) and A_(2) represents the area of circle and that of regular pentagon respectively, then A_(1) : A_(2) is

The area of a circle is A_(1) and the area of a regular pentagon inscribed in the circle is A_(2) . Then A_(1)//A_(2) is

If a_(1) and a_(2) are two non- collinear unit vectors and if |a_(1)+a_(2)|=sqrt(3), ,then value of (a_(1)-a_(2)).(2a_(1)-a_(2)) is

If a_(1) and a_(2) aare two non- collineaar unit vectors and if |a_(1)+a_(2)|=sqrt(3), ,then value of (a_(1)-a_(2)).(2a_(1)-a_(2)) is

If a_(1) and a_(2) aare two non- collineaar unit vectors and if |a_(1)+a_(2)|=sqrt(3), ,then value of (a_(1)-a_(2)).(2a_(1)-a_(2)) is
