I have encountered this question in my Giancoli Physics textbook, and I am pretty convinced that the answer should be A and E. But the solutions manual has neglected E as a potential answer and focused solely on A. Can someone point out what am I missing out? Perhaps a linguistic trick?
Water flows in a horizontal pipe that is narrow but then widens and the speed of the water becomes less. The pressure in the water moving in the pipe is
(a) greater in the wide part.
(b) greater in the narrow part.
(c) the same in both parts.
(d) greater where the speed is higher.
(e) greater where the speed is lower.
