Physics equations/23-Electromagnetic Induction, AC Circuits, and Electrical Technologies/Q:spaceTetherAndSimpleLoop

Only two of these problems have been placed on Quizbank (first and last)
 * Solutions to many wikiquiz questions (pdf)
 * Solution at page 821 of Example 23.2 Calculating the Large Motional Emf of an Object in Orbit. (openstax College Physics)
 * See also Space tether missions
 * This bad version of this quiz needs to be fixed so that more questions can be added here. Also a name change would help.
