A carrier wave of amplitude 15 V is modulated by a sinusoidal base band signal of magnitude 3 V. The ratio of maximum amplitude to minimum amplitude in an amplitude modulated wave is

Given below are two reactions, involved in the commercial production of dihydrogen (H\(_2\)). The two reactions are carried out at temperature "T\(_1\)" and "T\(_2\)", respectively

$$C(s) + {H_2}O(g)\buildrel {{T_1}} \over \longrightarrow CO(g) + {H_2}(g)$$

$$CO(g) + {H_2}O(g)\mathrel{\mathop{\kern0pt\longrightarrow} \limits_{Catalyst}^{{T_2}}} C{O_2}(g) + {H_2}(g)$$

The temperatures T\(_1\) and T\(_2\) are correctly related as :

Let P be the point of intersection of the line \({{x + 3} \over 3} = {{y + 2} \over 1} = {{1 - z} \over 2}\) and the plane \(x+y+z=2\). If the distance of the point P from the plane \(3x - 4y + 12z = 32\) is q, then q and 2q are the roots of the equation :
