Water from a tap emerges vertically downwards with an initial speed of 1.0 ms⁻¹. The cross-sectional area of the tap is 10⁻⁴m². Assume that the pressure is constant throughout the stream of water and that flow is streamlined. The cross-sectional area of the stream, 0.15 m below the tap would be: (take g = 110 ms⁻²)(A) 5 × 10⁻⁴ m²(B) 5 × 10⁻⁵ m²(C) 1 × 10⁻⁵ m²(D) 2 × 10⁻⁵ m² |
