Q1. George just graduated from college and is going on his first job interview. He has learned that there are two other candidates. Because of the information he has learned about the serial position effect, George asks to be either the first or the last candidate interviewed. Why?

Q2. Water is being pumped through a horizontal pipe that is 40.55 m long and 13.05 cm in diameter. A pump maintains a gauge pressure of 465 Pa at the large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length and diameter what gauge pressure must the pump provide to give the equal volume flow rate as for the first pipe?
