Question
Chapter 1, Problem 1RQ
To determine
The changes in height and area.
Expert Solution & Answer
Answer to Problem 1RQ
The area can be changed by zooming in to the field of view, width changes by a factor of 100 and length also changes.
Explanation of Solution
Area can be changed by zooming in and out of the field of view. Corresponding to every step size, there is an increase by a factor of 100.
The width of the picture increases by a factor of 100. Hence, the final width will be increased to 1600 m from 16 m. The length also gets altered with respect to the width.
Conclusion:
The area can be changed by zooming in to the field of view, width changes by a factor of 100 and length also changes.
