Given diameter of the copper rod = 1 cm So, radius(r) of the copper rod = 1/2 cm Let R is the radius of the cross section(circular) of the wire. Now, according to the question, πR2 *(18*100) = π(1/2)2 *8 => R2 *(18*100) = (1/2)2 *8 => R2 *(18*100) = 8/4 => R2 *(18*100) = 2 => R2 = 2/(18*100) => R2 = 1/(9*100) => R = √{1/(9*100)} => R = 1/(3*10) => R = 1/30 Now, thickness of the wire = 2r = 2 * 1/30 = 2/30 = 1/15 = 0.067 cm

Amrit Raj 6 years, 1 month ago

Let 3 + √ 5 = a, where a is a rational number = ✓5= a - 3 But √5 is an irrational no. So √5 = not a - 3 So it is contradiction of our assumption So 3 + root 5 is an irrational number.
