Water from a tap emerges vertically downwards with an initial speed of 1.0 ms-1. The cross-sectional area of the tap is 10-4 m2. Assume that the pressure is constant throughout the stream of water and that the flow is streamlined. The cross-sectional area of the stream, 0.15 m below the tap would be:(Take g = 10 ms-2)

• A. 2 × 10-5 m2
• B. 5 × 10-5 m2
• C. 5 × 10-4 m2
• D. 1 × 10-5 m2
