An ideal fluid flows through a horizontal pipe that narrows from a radius of \( R \) to a radius of \( \frac{R}{2} \). If the initial speed of the fluid is \( v \), what is the new speed, and how does the internal pressure change?(a) The speed becomes \( 2v \) and the pressure increases. , (b) The speed becomes \( 2v \) and the pressure decreases. , (c) The speed becomes \( 4v \) and the pressure increases. , (d) The speed becomes \( 4v \) and the pressure decreases. :
