Question 45: Question 46: Question 47: Question 48: (1 point) What is the value of the sum of r1and r2and how does it relate tothe ellipse properties? Is this true for all ellipses?
Question 49: (1 point) It is easy to create an ellipseusing a loop of string and two thumbtacks. Thestring is first stretched over the thumbtacks whichact as foci. The string is then pulled tight using thepencil which can then trace out the ellipse.Question 50: Assume that you wish to drawan ellipse with a semi-major axis of a = 20 cm and e = 0.5. Using what you have learnedearlier in this lab, what would be the appropriate distances for a) the separation of thethumbtacks and b) the length of the string? Please fully explain how you determine thesevalues.
