answers to the preceding question.
(You should produce a graph that
features (a) an average total cost (ATC) curve; (b) a marginal cost
(MC) curve; and (c) a line representing the hypothetical price of
$9 per ride. The graph should be labeled appropriately, have a
reasonable scale on the vertical (cost) axis and horizontal

In an experiment, a group of students will determine the
dielectric constant of paper. They have the following materials
available, as well as other materials traditionally available in a
high school physics lab.
_____ Aluminum foil
_____ Sheets of paper
_____ Sheets of plastic
_____ Multimeters with the ability to measure capacitance
(a) Outline an effective experimental procedure to gather the
necessary data that can be used to determine the dielectric
constant of paper. Place a check mark next to...
