Asked in MDCAT Test Series 32 β€” Fluid DynamicsModerate

In the following question, two statements numbered I and II are given. There may be cause and effect relationship between the two statements. These two statements may be the effect of the same cause or independent causes. These statements may be independent causes without saving any relationship. Read both the statements in question and mark your answer as:A. If statement I is the cause and statement II is its effect;B. If statement II is the cause and statement, I is its effect;C. If both the statements I and II are independent causes;D. If both the statements I and II are effects of independent causes;E. If both the statements I and II are effects of some common causes;I. She got admitted into one of the top colleges.II. She worked day and night to achieve a good score in the entrance exam.

Correct answer: B. B. If statement II is the cause and statement I is its effect;

  • A. A. If statement I is the cause and statement II is its effect;
  • B. B. If statement II is the cause and statement I is its effect;
  • C. C. If both the statements I and II are independent causes;
  • D. D. If both the statements I and II are effects of independent causes;
  • E. E. If both the statements I and II are effects of some common cause;

Explanation

The correct answer is Option B: Statement II is the cause and Statement I is its effect. Statement II describes the hard work and dedication to achieve a good score in the entrance exam, which likely resulted in her admission to one of the top colleges, as stated in Statement I. The other options are incorrect because they either suggest independent relationships or common causes, which are not applicable in this scenario.

About Fluid Dynamics

Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
