mass.
B. dividing your mass by
4.
C. dividing your weight by 2.
D. dividing your weight by 4.
2. Suppose you are standing on a bathroom scale when you are
flying in a jet airplane. For a moment the scale reads less than

7. A friend of your joins a weight loss group. Unfortunately, they try
to control the readings on the scales by having you weigh yourself
on either level ground or with the scale on a slight slope. How will
the two weights obtained by these two different methods
compare?
