Mathematics

Let f(x) = x⁴ + ax³ + bx² + c be a polynomial with real coefficients such that f(1) = −9. Suppose that i√3 is a root of the equation 4x³ + 3ax² + 2bx = 0, where i = √−1. If α₁, α₂, α₃, and α₄ are all the roots of the equation f(x) = 0, then |α₁|² + |α₂|² + |α₃|² + |α₄|² is equal to _____ .

Physics

Two large, identical water tanks, 1 and 2, kept on the top of a building of height H, are filled with water up to height h in each tank. Both the tanks contain an identical hole of small radius on their sides, close to their bottom. A pipe of the same internal radius as that of the hole is connected to tank 2, and the pipe ends at the ground level. When the water flows from the tanks 1 and 2 through the holes, the times taken to empty the tanks are t₁ and t₂, respectively. If H = (16/9)h, then the ratio t₁/t₂ is _____.

Chemistry

Complete reaction of acetaldehyde with excess formaldehyde, upon heating with conc. NaOH solution, gives P and Q. Compound P does not give Tollens’ test, whereas Q on acidification gives positive Tollens’ test. Treatment of P with excess cyclohexanone in the presence of catalytic amount of p-toluenesulfonic acid (PTSA) gives product R. Sum of the number of methylene groups (-CH₂-) and oxygen atoms in R is _____.
