  1. Question 1

    Q1. An open water tank develops a small hole in its side at a depth of 5.0 m below the water surface. Calculate the speed of efflux.

    • A) 4.9 m/s
    • B) 9.8 m/s
    • C) 9.9 m/s
    • D) 19.6 m/s

    Answer: 9.9 m/s

    Explanation: According to Torricelli's theorem, speed equals sqrt(2gh). With g=9.8 and h=5, the calculation yields approximately 9.9 m/s. Option B is just g.
