In the above figure, suppose the physical load driven by the motor is reduced. As the motor speeds up, the CEMF ____________________ (increases, decreases), the net voltage across the armature ____________________ (increases, decreases), and the voltage at the junction between R8 and R9 ____________________ (increases, decreases). It is amplified by op amp 1, causing the summing amp to produce a voltage that is ____________________ (less, greater) negative turns Q1 on ____________________ (less, harder), and causes the SCR to fire ____________________ (sooner, later), which ____________________ (increases, decreases) the motor speed back to its desired rpm.
Fill in the blank(s) with the appropriate word(s).

A platform was originally designed as a rectangle 12.00 meters long and 8.00 meters wide. The rectangular design is replaced with a platform in the shape of an ellipse. The elliptical platform will have the same area as the original rectangular platform and the major axis is 16.00 meters. Determine the minor axis rounded to 3 significant digits.
