Physics 272: Honors Physics II

Spring 2017

- Finish discussion of Archimedes' principle

- Fluid flow: current density and continuity

- Bernoulli's equation

1. At the end
of Monday's lecture, we did an iclicker question on ducks floating
in water that most students got wrong. Here is a second chance on
a similar question! Note that the main reason for getting the
clicker question wrong was the implicit (wrong) assumption that
the amount of water in each beaker is the same -- but think about
it: the **levels** are the same, so t**he amount of water**
has to be different in the three cases. Now do question #1 in the
quizlet.

2.
Introduction to the concept of "flow rate." Imagine a museum with
one entrance and one exit. People enter the museum at the rate of
127 per hour (that's about 2 per minute). This is the "number flow
rate" into the museum. Now do question #2 in the quizlet.

3. More on the "number flow rate." If there is more than one exit, you have to add the number flow rates to get the total rate at which people exit the museum. Now do question #3 in the quizlet.

YOU SHOULD PREVIEW THE QUIZ QUESTIONS HERE
TO BE READY TO ENTER THEM WHEN YOU START THE QUIZ IN QUIZSTAR.
