  1. Question 1

    Q1. Water flows through a horizontal pipe of cross-sectional area 4.0 cm² at a speed of 2.0 m/s. What is the speed in a constricted section of 2.0 cm²?

    • A) 1.0 m/s
    • B) 4.0 m/s
    • C) 8.0 m/s
    • D) 0.5 m/s

    Answer: 4.0 m/s

    Explanation: Equation of continuity states speed is inversely proportional to area. Halving the area must double the speed to maintain constant flow rate.
