Options

  1. A(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
  2. B(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
  3. C(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
  4. D(A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Correct answer

D. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Step-by-step solution

A Venturi-meter is a device used to measure the flow speed of an incompressible fluid, and it works on Bernoulli's principle. Hence, (A) matches with (II). Hydraulic brakes in automobiles operate on Pascal's law, which allows pressure to be transmitted equally throughout the brake fluid. Hence, (B) matches with (I). A falling raindrop attains a constant terminal velocity due to the viscous drag of air balancing its weight, a phenomenon described by Stokes' law. Hence, (C) matches with (IV). A mercury barometer is a
