MDCAT Physics MCQ #1874

  1. Question 1

    Q1. Water flows through a horizontal pipe with a velocity of 2 m/s. If the pipe's cross-sectional area is halved, what is the new velocity?

    • A) 1 m/s
    • B) 4 m/s
    • C) 8 m/s
    • D) 0.5 m/s

    Answer: 4 m/s

    Explanation: Using the equation of continuity (A1v1 = A2v2), the new velocity is 4 m/s because area is halved. Option A is incorrect because it assumes the velocity remains the same.
